The goal of this repository is to keep a version of a useful development boards for my MySensors projects based on atmega 328, esp32 and nrf24l01 module, so I do not need to wire all componentes into a breadboard.
Features:
- Almost all I/O pins available for direct connection
- Uses 3.3V Boost Buck for an input up to 5V (Considering that the sensor will be powered by a TP4056 battery charger)
- If voltage regulator is wired by a connector headers instead of soldering, it would be possible to use a different voltage regulator (keep in mind that nrf24 module works with no more than ~3.6V or could be damaged)
- Internal voltage of 3.3 for the atmega 328
- NRF24L01 wired with a 10uF capacitor for noise reduction
- Reset button
- On board jumpers to disable 16 MHz crystal (and use internal 8 MHz from atmega 328)
This is the way it looks like:
Features:
- All I/O pins available for direct connection
- NRF24L01 wired with an optional capacitor for noise reduction
- Err Tx and Rx led diodes for mysensors capability
