Also fits the S2-SOLO.

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.

As the S3 also 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. This version also features an onboard LED for testing.

NOTE: Due to a mistake on my part the reset and boot mode switches are labeled the wrong way around. I'll cover them with stickers before shipping if i remember to lessen confusion.
