## Description

Makes it easy to program modules before soldering them into whatever contraption you're building, or just to use as a temporary development board. You can always use this adapter to just put some wi-fi and OTA code onto the module and later reprogram through the network.

Based on the original by [Solder Party](https://lectronz.com/products/esp32-c3-wroom-flexypin-adapter) who's also located here in Sweden.

As the C3 has native USB support, there isn't a lot needed to program them. The added changes are a USB-C port, a voltage regulator, two switches for reset and boot mode and any required other components. Of course compatible with USB-C to C cables.
