Yo! This project is still a Work In Progress. Instructions, board layouts and BOM might change!
Donate to support Open HardwareThis is yet another small MySensors Sensor node with:
Atmega328p
ATSHA204A
W25X40CLSNIG
voltage divider
SMD NRF24L01+
DS18B20 (either directly soldered to board or via cable for external measurement)
3 LEDs (SCK, D6, D7, on backside)
2 Pushbuttons (Reset, D2 (interrupt) or D5)
D2 can either be connected to NRF24L01+ or be used for interrupt pushbutton
I populated the boards using my home-made reflow oven. The boards work properly, I power them directly from a 16340 Li-Ion cell. I also printed a universal case, but I can't upload the stl file here.
I use the board as a cheap board to monitor the windows and for lux sensing right now.
More will follow soon....
