This is a general purpose test/dev board with an ESP32-S3-MINI-1-N4R2 module.
The test board has a USB-C connector for power and USB JTAG/Serial. It also has a 5 pad serial programming connection if needed. It exposes 38 GPIO pins on pads for 0.1" header pins (not GPIO26 as used internally for PSRAM). It also has a DC power connection, and a simple status LED (GPIO0).
