A simple & compact esp32 development board that can also act as a ch32 debug probe
What is this
A simple esp32-s2 development board! It has an onboard antenna and a USB bootloader, allowing easy programming and usage. The ESP32-S2 has a built-in USB PHY, allowing easier usage over the older chips.
The board also has an onboard antenna, eliminating any need for external components.
It also connects GPIO8 & 4, and GPIO9 & 6 with a 10k resistor, so it can be directly used as a CH32 debug probe.
Usage
Just plug the USB into your computer while pressing the BOOT button, and it'll appear as a USB device! You can then program the board using Espressif's SDK.
The pinout is also present on the back of the board, so there is no need to look up the pinout on the internet.
Open source
The design is wholly open-source; I made a few extras, so I'm selling them at cost.
