Description

Three ESP32 boards with a built-in LiPo charger that keeps your program running when USB-C is unplugged, plus three shields.

Highlights

• Keeps running off USB. The power path runs the board from USB while the battery charges, then switches to the battery without a reset.
• 500 mA charger. For a single-cell 3.7 V LiPo or protected 18650 on the JST-PH 2.0 port (battery not included).
• Battery monitoring. Bridge the BATTERY MONITOR pads on a shield to read the battery on IO36 through a 1:2 divider.
• Three shields. 2.54 mm header, spring terminal and screw terminal, each with its own on/off switch and fully assembled.
• Solder the headers. Header strips ship unfitted.
