eduArdu update

eduArdu

I blogged about eduArdu the EUR 15 educational Arduino based board at the beginning of October, the plan was to have prototypes in 2 weeks which unfortunately didn’t happen, anyway now we have first prototypes built and work on the software support.

eduArdu2

We are preparing Arduino libraries for all features:

  • scrolling text and writing images on the LED8x8 matrix
  • playing single tone and multi tone sounds on the buzzer
  • measuring the temperature with the on-board sensor
  • measuring the light with LDR
  • detecting movements with the PIR sensor
  • reading distance to objects with Ultrasound sensor
  • reading the Joystick status
  • driving servo motors connected to the two  connectors
  • reading audio signals via microphone
  • driving RGB and the red LEDs on board
  • reading resistance on the 6 GPIOs to implement Makey-makey
  • receive IR remote commands and transmit IR codes to control air conditions, TVs etc.

TuxCon is preparing free Arduino day in “Prof. Asen Zlatarov” school in Parvomay on December 15th, where volunteers will teach students how to program in Arduino and make the first steps in programming and electronics.

TuxCon is non for profit organization and does all events free of charge aiming to spark interest in kids for IT technologies. If you want such event to be provided in your school please write in TuxCon facebook group: https://www.facebook.com/tuxcon.mobi/

Scratch gets lot of attention for enabling even very small kids to program with visual blocks. We though it would be good eduArdu to support it and add blocks to Scratch which to allow embedded board programming with Scratch.

I’ve tested Scratch 1 many years ago, it was relatively easy to add hardware board support at that time via Python web server running jango and communicating with Arduino fermata. It’s obsoletenow and in maintenance mode i.e. no bug fixes and developments.

Scratch 2.0 was re-writen in Action script and uses Adobe Flash technology for animation, really bad choice as we did try to use it several times with Linux and never succeed. This version is also in maintenance mode now.

So we moved to test Scratch 3.0 which is re-written in HTML5 and looks great, but unfortunately they closed the extensions for boards and now support officially just Microbit and Lego. Probably this is their way to get some money for their efforts. There are issues open from people who use other boards and wanted to migrate their old projects to 3.0 posted almost year ago without any action, so we really are puzzled after all this popularity they got, this is the best way to shoot themselves in the leg.

Fortunately there are many alternatives to Scratch, like Snap

It’s totally open for adding blocks and has tens of GitHub projects adding blocks for different robot platforms, Arduino, Raspberry pi etc embedded stuff.

So we will add support for eduArdu in Snap too.

eduArdu is new Open Source Hardware educational board targeting kid’s digital education

eduArdu

Few weeks ago we got contacted by Digital Kidz an non for profit foundation which goals are to support digital literacy and innovative education in the schools. They needed hardware board, which to be easy to use and to allow entry level programming with Scratch and Arduino for beginners. They were ready to pay for the development, but we liked the idea and decided to design one such board for free and release it as Open Source Hardware.

The result is here:

eduArdu-explained

The design is based on ATmega32U4 which is easily programmable with Arduino IDE. We named it “eduArdu” as this is educational board programmable with Arduino.

eduArdu has these features:

  • USB connector for programming and power supply
  • red LED matrix 8×8 which allow text and small image animations
  • X-Y Joystick with push button for navigation
  • Microphone for Audio sensing and interactions
  • Speaker for Audio output
  • Light sensor with LDR
  • Digital temperature sensor
  • RGB LED
  • Status LED
  • IR remote control LED and receiver to talk to other boards, TVs, Air conditioners, etc.
  • PIR motion detector up to 6 meter range
  • UltraSound distance measurement sensor
  • Two SERVO motor connectors (to build easily two wheel robot car)
  • LiPo charger so the whole board may work on LiPO power
  • 6 Makey-Makey style buttons
  • UEXT connector for additional modules

The board is shaped like Game console. The first prototypes will be ready in 2 weeks.

Target sale price is EUR 15.00

New ESP32 Development board in stock ESP32-DevKit-Lipo target handheld applications with build in LiPo charger

ESP32-DevKit-LiPo

ESP32-DevKit-Lipo is pin to pin compatible with Espressif ESP32-CoreBoard (ESP32-DevKitC) board, but adds additional LiPo charger and battery connector, allowing board to work from LiPo battery when external power supply is missing.

Tomorrow 16.10 at SofUnitConf in Paradise Center in Sofia we will have Workshop with this board to show how easily it could be programmed with JavaScript and Espruino.

ESP32-POE Open Source Hardware IoT development board with WiFi/BLE/100Mb Ethernet with 802.3 POE is in stock!

ESP32-POE-1

ESP32-POE board is now in stock. The prices start from EUR 14.36 for 50 pcs order.

This board offers Open Source Hardware / FOSS solution and building block for distributed sensor network with power over existing LAN infrastructure.

Possible use cases are Home automation, Industrial machine logging, remote environmental monitoring, access control, remote displays etc.

The board contains ESP32-WROOM-32 module with WiFi/BLE and Ethernet connectivity , RESET and USER buttons, micro SD card, LiPo battery charger and LiPo connector which allow board to work even with power supply drops.

The UEXT connector on the board can be used to connect many different sensors like:

Si3402-B chipset takes care for the power over ethernet, it’s IEEE 802.3 compliant, including pre-standard (legacy).

Important notice, to keep board compact and as it’s main purpose is to connect to cloud different remote sensors there is no galvanic isolation between board and the power delivered by the LAN switch or router.

ESP32-POE has internal programming interface and you can program it with Espressif SDK or Arduino via USB cable. As the board is not galvanic isolated from the Ethernet power supply, before you connect the USB cable to your computer you should remove the Ethernet cable or you should use USB-ISO between your computer the ESP32-POE!

 

New Product in stock – mini PIR sensor PIR-SB312

pir

PIR-SB312 is small low power PIR sensor with digital output. Very easy to connect to Arduino and OLinuXino linux boards as can be powered from 2.7 to 12V.

It can sense objects from 3-5 meters and  due to it’s small size it’s easy to hide.

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.

 

iCE40HX8K-EVB OSHW FPGA board is in stock

iCE40HX8K-EVB-1

iCE40HX8K-EVB is upgrade of our iCE40HX1K-EVB with more logic cells FPGA so bigger Verilog projects could be synthesized.

GPIO1 34 pin bus is same as iCE40HX1K-EVB and all DAC, ADC, IO, etc modules are compatible, on top of this there are plenty of additional GPIOs on 4 40 pin 0.05″ step connectors.

512KB fast SRAM is on board, with iCE40-IO board you  can connect VGA monitor and PS2 keyboard, so you can make your own custom CPU (for instance RISC-V) computer with monitor and keyboard.
