Yet another MySensors ATMEGA328p + NRF24L01+ node with built in TP4056 LIPO battery charger and low power consumption 3V3 regulator.
Headers for :
Works on internal or external oscillator.
Battery and charging voltages sensors (filtered low current dividers on A6 and A7). Charging and iddle status signals connected to micrcocontôler inputs D0 and D1.
All SMD resistors and capacitors are 0805 sized for easy iron soldering.
Can work more than one week on small cheap drone 300mAh charged battery with HTU21D reading and sending every 10s.
Supports cheap small 6V solar panel or 5V supply for charging.
