Description
Description
The project goal is to have 10 ESP8266 regroup on a single PCB.
- Only power supply (5V) is provided to the ESPs boards. No power management is provided by the board itself. It require a proper 5V power supply with enough output current capability.
fyi : Absolute maximum current drawn by 10 ESP8266 (~2A). - Spacing for ESP headers is 1 inch (25.4mm) : adaptation to your own ESP board may be requiered.
- 5V power supply can be propagate from one PCB to another using PWR1 or PWR2 Molex connector. This allow you to have 1 power supply feeding multiple PCB.
There is also a slot to power a 5V fan for cooling and a potentiometer to adjust the fan speed (not tested yet).
