New Open Source Hardware Color TFT LCD Display 320*240 pixels with Touch panel module for direct connection to ESP32-EVB via UEXT

MOD-LCD2.8″RTP is Color TFT LCD 320*240 pixel resolution with touch panel and connects directly to ESP32-EVB via UEXT connector with cable.

Now you can add fancy UI to your IoT projects!

 

New Board from Espressif – ESP32-LyraT in stock

ESP32_LyraT3

ESP32-LyraT is low cost IoT speech recognition board. It can work with many audio sources and have provisions to connect speakers, camera and LCD display.

The board documentation is skinny as this board is very new and we got limited quantity of one of the very first produced boards.

 

MOD-BME280 precise Humidity, Temperature and Pressure sensor Open Source Hardware module with UEXT and Breadboard connector

MOD-BME-u

BME280 is digital humidity, temperature and pressure sensor with I2C and SPI interface.

You can see on this link comparison of different Humidity sensors

The operating conditions are:

  • Temperature -40..+85C;
  • Humidity 0…100 % Rh;
  • Pressure 300…1100 hPa  (+9000m..-500m above sea level);

The sensor works on 3.3V and is with very low power consumption 0,1..3,6 uA.

The easiest way to connect MOD-BME280 is with UEXT connector to any board with UEXT connector as shown on the picture above.

For boards which has no UEXT connector MOD-BME280 can be connected via four jumper wires on breadboard:

MOD-BME280-b

The KiCad files are uploaded on GitHub.

The demo software use Adafruit BME280 libraries with two small modifications. The default address in MOD-BME280 is 0x76 while Adafruit library is set to 0x77.

UEXT connector requires D8 to be set LOW to power and 10 ms delay to settle the power before addressing the sensor. The code is at GitHub.

When you run it you will see this:

The sensor is very precise, if you move board up and down you can see altitude changes. The 171 meter is the altitude of Olimex building.

MOD-BME280 is perfect for IoT application for environmental conditions logging due to the low power consumption and precise measurements. It can be used both for indoor and outdoor applications.

Amazon FreeRTOS IoT ported on STM32-E407 board

Amazon_FreeRTOS_How_It_Works.cefaf934412cd0930f9481ba1f31e142d4097a36

Amazon announced few weeks ago about their AWS stack support for FreeRTOS. As their development kit is not yet shipping, Roedan Embedded Systems decided to fork their GitHub repo and port to available boards like STM32-E407.

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:

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.

 

Sneak preview of new OSHW IoT board: ESP32-Gateway

ESP32-GATEWAY

ESP32-EVB really took us lot of time to complete mostly due to the not so complete documentation around Ethernet and our own silly errors. Also we wanted to add so many interfaces there to may people evaluate them all: Ethernet, CAN, Infrared, Relays LiPo UPS etc etc and the board become 75×75 mm. The price also went from EUR 22 to EUR 26.

In parallel we quietly were working on stripped version named ESP32-GATEWAY, as the name says we wanted just to keep here the connectivity: WiFi, BLE, Ethernet, USB for programming and micro SD card.

All available GPIOs are made on 0.1″ step strip at the bottom of the board, and two nice mount holes:

ESP32-GATEWAY-1

Today we assembled the first prototypes and we will test tomorrow. If everything is OK we will run production. We already have 100 blank PCBs ready as after so much time spent on ESP32-EVB we do not expect any troubles, but still wanted to reduce the risk to throw in the garbage bin more than 100 boards if we missed something.

So hold your breath if everything is OK we will have 100 boards for sale next week 🙂

The price of ESP32-Gateway will be EUR 22.

ESP32-WROVER-KIT is back in stock

esp32-wrover-kit

The popular ESP32-WROVER-KIT is back in stock!

 

EDIT: The new batch has ESP32-WROVER module on it:

ESP32-Wrover-2

Instead of CH340 USB to Serial now it have FT2232HL wich implements two Serial channels one for programming one for debugging.

Also as these were assembled end of May they contain WROVER modules with 4MB of RAM and ESP32 chip REV.1.
