Ever wondered how much current your USB devices use and how stabile is your USB voltage? Now you can measure!

USB-POWER

Some USB devices like 3G modems, WiFi etc in active mode draw lot of current and cause problems, to monitor the current consumption and how stabile is your USB voltage you can use this USB-POWER-METER.

The consumption is measured and displayed with 10mA accuracy. Voltage with 10mV accuracy.

Is it hot or not? Contactless preciese Infra Red temperature measurement with Open Source Hardware MOD-IR-TEMP

MOD-IR-TEMP-bb

MOD-IR-TEMP is UEXT module which could be easily connected to all our boards with UEXT connector. It has MLX90614 contactless Infra red thermometer which allow you to measure objects temperature from distance.

MLX90614 has internal temperature sensor which can sense temperature in range -40+125C and Infra red camera which can sense external objects temperature in range -70+380C with resolution 0.02C and is calibrated with precision 0.5C in range 0-50C.

There are two ways to connectMOD-IR-TEMP to other boards – first is to use UEXT connector:

MOD-IR-TEMP-w

MLX90614 works on +3.3V so it’s important if you use Arduino board to make sure it operates at 3.3V or you will damage the sensor.

OLIMEXINO-32U4 has jumper which selects on what voltage it operates 5 or 3.3V you must put the jumper in 3.3V.

The sensor is read via I2C, Adafruit has library included in Arduino library manager.

UEXT onOLIMEXINO-32U4 has power enable and to operate D8 pin should be placed in LOW state.

Here is code:

#include <Wire.h>
#include "Adafruit_MLX90614.h"

Adafruit_MLX90614 modIrTemp = Adafruit_MLX90614();

void setup() {
 pinMode(8,OUTPUT);   //the following two lines enable power supply 3.3V on UEXT connector
 digitalWrite(8,LOW); //you do not need them if you use wire jumpers
 modIrTemp.begin(); 
 Serial.begin(115200);
}

void loop() {

Serial.print("Ambient = "); Serial.print(modIrTemp.readAmbientTempC()); 
 Serial.print("*C\tObject = "); Serial.println(modIrTemp.readObjectTempC());

 delay(1000); // can adjust this for faster/slower updates
}

If you use breadboard you should connect MOD-IR-TEMP GND, 3.3V and SDA to D2, SCL to D3. In this case you do not need to set D8 LOW to operate.

MOD-IR-TEMP allow precise temperature measurement from distance, we are doing some experiments to measure PCB reflow temperature from distance and to measure body temperature.

Our experiments show that how good the temperature is measured depend on object surface. Dark objects temperature is measured better than shiny objects.

If you place your hand in the front of the sensor the temperature is measured correctly from distance 0 to about 5 cm, then the measurement start to register lower temperature. Our guess is that the build in optics has limitation, if you want to measure temperature from greater distance you should add proper optics.

 

New product in stock air/water normal closed magnetic valve driven with 12V with quick connect for 6 mm sleeve

Oli DudeN01

We have new product in stock:

WATER-VALVE-6.5MM-12VDC

WATER-VALVE-6-5MM-12VDC is electro-magnetic valve with normal closed path. It’s driven with 12VDC/0.54A and when power supply is applied opens the valve. It has quick connect for 6 mm sleeves and makes water/air pipes attachment and dis-attachment easy. The valve can work with 0-0.8MPa (0-8 bar, 0-116 psi, 0-7.9 atm) pressure of the air or water.

With this valve and ESP32-EVB you can make IoT watering system, which allow you to switch on and off water supply to your garden or plants via internet.

The demo code is written with Arduino for ESP32-EVB and sources are at Github.

When the server is run you can view the status in your local network:

Screenshot from 2017-12-07 14-59-34

You view the current time and with arrows can adjust time when the watering to start or stop. You can also directly drive your valve with ON and OFF buttons.

 

New Product in stock MOD-WIFI-AR9271 libre drivers and firmware WiFi dongle

MOD-WIFI-AR9271-2

AR9721 chipset is the only one on the market with completely open source linux drivers and firmware, this make it WiFi chipset of choice for people who respect their freedom.

We have MOD-WIFI-AR9721-ANT for quite some time and it’s very popular item, but the 200mm antenna make it not quite small. Now we add to our web shop the version without external antenna. It’s with 85 x 25 x 10 mm dimension and have same working distance as the external antenna version.

TERES-I Do It Yourself Open Source Laptop update

TERES

We are glad to tell you that we finally have TERES-I released!

It was long way but finally we have laptop which works satisfactory to be released.

What we changed since revision B?

A64

Main board now is with 2GB DDR3 ram and 16GB eMMC Flash memory. We add two new connectors CON3 and CON4 to interface the further FPGA module which will turn TERES-I in oscilloscope and Logic Analyzer.

The debug UART multiplexes now with Headphones, so you can plug serial cable to headphone jack and re-direct Debug console UART to Headphone jack. After you finish debugging you can restore Headphones functionality to this jack. We work on USB-Serial cable with headphone jack for the laptop.

We got new 9500mAh battery which now is in TERES kit.

Another improvement is 5V 3A adapter which allow battery to be charged to full in 3 hours. The adapter has charge indicator and comes with convenient 3 meter cable, so you can lay on your bed while your laptop is connected to power supply.

Please give us some days to update all latest Hardware files on Github.

Work-in-progress User manual and Assembly instructions are here.

The software is let’s say about 90% ready state, but works satisfactory even now.

The laptop comes with pre-installed Ubuntu 16.04 LTS with Mate, Firefox browser, Video player, Open Office, Arduino IDE and IceStorm for FPGA development. We will try to include KiCAD later.

Python libraries to access I2C, SPI, UART, GPIOs will be add when ready.

FPGA module with ADC/DACs/IOs will be ready in the next months, it will be easy to insert inside with the other existing boards.

TERES-I is now for sale.

This project took lot of time and we have long list of registered interest for ordering, bigger than the number of laptops we could build in the first run. We guess many of these registered users are duplicated for black and white version and will take just one, but be prepared that after you order your laptop will not be shipped immediately but in 2-3 weeks (or less) depend on workload and number of orders to be processed. Once/if the first run is sold we will make the laptop out of stock and will work on second run which may take few months to complete, but we will produce this laptop until there is interest for it, so if you do not succeed to order during the first run, do not give up 🙂

 

EDIT: very important notice to add: TERES-I is not designed to scratch everyone’s itch. If you want high performance laptop. If your work involve 8-16-24 core processor power and 4-8-16-32GB RAM memory to do video editing or to compile Linux kernels and Android distributions etc. this is not your laptop! TERES-I software is far for complete and not using 100% performance and features of A64 chip yet, it will work much better and faster in future, now it’s work satisfactory for daily work in motion.

When TERES-I was designed we wanted to make laptop which allow you to travel and do internet browsing, emails check, embedded code development, programming arduino, making PCBs etc. With the further modules it will become more like traveling laboratory to sniff protocols on hardware level, to generate signal patterns etc.

 

New Universal System On Module in SO-DIMM 204 pin form factor

SOM204-EVB

We have now several SOMs for A13, A20, AM3352, RK3188.

Each of them with different layout and pinouts as our initial intention was to expose all possible features of every processor.

The experience we got from selling the SOMs for the past 5 years is that 99% of customers do not need all specific interfaces, but few common interfaces.
For instance very few customer need 12 UARTs and 6 I2C in their design, but almost all need Ethernet, HDMI, SATA etc.

Another important point is that soon or later the project they working on scale up and they need more memory or more processor power and with the current SOMs they have no option but redesign.

Every big customer need longevity assurance. They do not want to change their design every couple of years when the SOC manufacturer obsolete their processors, they do not want to re-design every 6 month when new processor with 4-6-8-10-12-24 cores appear to the market with preliminary buggy software support.

So with the years one another idea evolved – we should try to make one universal SOM layout with known interfaces on known pinout, so if customer need more memory he just switch to SOM with same pinout but more memory, if need more power he switch to SOM with same pinout but more powerful SOC.

We have experience with Allwinner, Rockchip and TI, so we considered these processors as potential new SOM SOCs:

A20, A64, RK3399, AM335X

After long discussions we decided that the universal SOM should have these signals:

  • USB-OTG
  • USB-HOST1
  • USB-HOST2
  • HSIC
  • USB3
  • PCIe
  • Ethernet1 Megabit/Gigabit
  • Ethernet2 Megabit/Gigabit
  • WiFi+BLE
  • SATA
  • SD-CARD
  • CAN
  • IR
  • CSI
  • HDMI
  • VGA
  • Audio In
  • Audio Out
  • SPDIF
  • UEXT1 -> SPI1, I2C1, UART1
  • UEXT2 -> SPI2, I2C2, UART2

     

The first SOM204 we made is obviously for A20.

Here are the schematics of A20-SOM204 and SOM204-EVB.

Here is our A20-SOM204 prototype:

A20-SOM204

Features are: 1GB RAM, 4/8/16/32/64GB eMMC Flash, Gigabit Ethernet interface, 2K EEPROM,
Optional features not assembled by default: SPI Flash with hardware WP, Second Megabit Ethernet.

With this SOM we tested A20 with two Ethernet interfaces: one Gigabit and one Megabit working together. The practice prove A20 can have two separate working Ethernets, but there is one issue both share same clock, so if the both Ethernet works together they can be only Megabit.

The second SOM204 module we work on is with A64.
The features are 2GB RAM, 4/8/16/32/64GB eMMC, Gigabit Ethernet interface, 2K EEPROM
Optional features not assembled by default: SPI Flash with hardware WP, Second Gigabit Ethernet (USB-Gigabit), SATA (USB-SATA), CAN.

The third SOM204 module we work on is with RK3399.
The features are 4GB RAM, 4/8/16/32/64GB eMMC, Gigabit Ethernet, PCIe, USB3, 2K EEPROM
Optional features not assembled by default: SPI Flash with hardware WP, Second Gigabit Ehternet (USB-Gigabit), SATA (USB-SATA), CAN.

A20-SOM204 and SOM204-EVB will be for sale in November. Prices will be comparable to existing A20-SOM A20-SOM-EVB.

A20-SOM204 is separate product and not meant to replacement A20-SOM neigher we have intentions to discontinue A20-SOM. Both products will be active and in production.

Software support for all SOM204 modules will include Android and Linux.
