Solar power meter measures the voltage, current and power of my 40W solar panel.
On the PCB are two electrolytic capacitors, connectors, 3.3V stabilizer, ESP-01, voltage and current sensor INA219.
OLED display is screwed to the box.
The box can be fitted on a DIN rail.
Also, since this is contest in partnership w/ Arduino, your project needs to use at least one Arduino to be eligible for the contest. Any ideas for adding an Arduino to add anther aspect to your project?
