A development / test board.
A small one, as small as you can get with sensible GPIO pins. Main board 30x32mm
This is a neat board and small. The wide voltage range, the WAGO power connector. The high power regulator for peripherals. It makes it a key starter board for any project.
Very small
An ESP32 with some oomph - dual processor, 4M flash 2M SPIRAM plus base RAM. Serious SoC.
All of the GPIOs available!
Small, and the power supply is a TI buck converter that is up to 2A at 3.3V to help supply peripherals you are connecting.
USB-C for power and debug/flash, or WAGO for DC from 5V to 17V
WS2812 LED on GPIO0 - does not stop the general use of GPIO0, but means you can use the LED if driven with WS2812 drivers.
