Peripheral Station 24.1

1. Wemos Lolin32 Lite

The Peripheral Station 24.1 (PS24.1) is implemented with the ESP32 Wemos Lolin32 Lite and its clones (board: lolin32_lite).


Using the ESP32-D0WDQ6 module with 2 rows of 13-pin holes (headers supplied but NOT soldered on).

Many other Peripheral Stations are available if you want soldered in headers or you do not need the built-in battery charger.

Note this is the cheaper "Lite" version, not the "standard" version:

Available Pins Standard version Lite version
3V3 2 1
5V 1
GND 5 1
GPIO 21 21

PS24.1 is very small and low cost. If you need headers get the PCC1, if need camera get the PCC2 (which also has headers), but they do NOT have a battery port.
