Make a donation to FanfanFC-001 : Basic MySensors Node on CR2032
Tested and works
Versatile MySensors node Compatible with sensebender (Led on A2, Crypto on A3, Flash on D8)
Very first schematic design, very first PCB design, very first SMD solderings. This is my "hello world" in a new realm.
- Designed from scratch
- Designed to be castelizable (no componant bottom-side, ICSP and FTDI pogo-pin friendly), shieldable (all pins spaced by 2.54mm) and breadboard friendly (ICSP+FTDI without pins)
- Most ATMega pins exposed for extensions
- Red led connected to A2
- Reverse polarity protection
- Overvoltage protection
- Mounting holes (M2 screws)
- RF ground plane
- Compact and dense placement for very small footprint (only 47 x 26.2mm)
- Hand solderable
- Embedded NRF24L01+ with Ceramic antenna
- Embedded ATSHA256 encryption chip connected to A3 (optional)
- Embedded AT25DF512 SPI flash for OTA connected to D8 (optional)
- CR2032 holder at the bottom side (optionnal)
- (expensive) Temp/Hum/Press BME280 sensor (optionnal)
TODO:
- Remove optional (and expensive) BME280 sensor or replace it with a SI7021
