Johan Kanflo has been using Arduino compatible boards based on Tiny328 MCU with an ISM radio module (wireless Arduino clone), but he found that finding a case was not easy, and was quite not ready to to design its own and print it with a 3D printer. So instead he shrank the board to fit into an AA battery case bought on Ebay with two AA batteries taking the remaining slots. That’s the result.
AAduino board specifications:
- MCU – Atmel ATMega328p clocked at 8 MHz to save power
- Radio – RFM69C ISM transceiver module
- Sensors – Two DS18B20 temperature sensors
- Misc – Indicator LED
- Keystone battery terminals rotated 180° to act as positive and negative terminals.
- Power – 2x AA batteries
The project is also open source hardware, with all hardware files released under the MIT license on Github, where you’ll also find a demo sketch for the board.
Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting his job as a software engineering manager, and starting to write daily news, and reviews full time later in 2011.
Nice, next step is to replace the atmega by an esp8266…
Hi, this could be great for play with mysensors library and create nodes for sensor data.
looks like mysensors sensermicro
a lot of fun 😉
