Description

ESP32 Breakout Board with SMD components, where available.

 

Connect either External Power (up to 20VDC), or a Battery charger. DO NOT connect these two in parallel. it is the same terminal.

 

Use Jumpers to Set:

  • Bat Charger On - Off.

this will connect the Charger terminal to the Battery terminal.

  • 9V Bypass

option 1: 9V from 7809 is distributed across the +9V terminals. to be used when having Batteries or Power of over 10VDC.

option 2: to be used when having Batteries of 7.2VDC, which is not enough to power up the 7809. it bypasses the 7809, and distributes this power across the +9V terminals

  • Battery or Power Selector

Choose between powering by Bat or by External Power (=Charger)

 

To Connect with Arduino IDE

Use the Arduino IDE to connect via the micro usb port

assign port numbers as per the labels (just the number, i.e. "pinMode(0, OUTPUT);" is labeled "IO0")

PWM Ports are labeled ~

Analog ports are labeld
