What is this?
2231puppy's Project Stida RoboCloud is an ESP32-S2 robot controller board. It has Wi-Fi courtesy of the ESP32-S2 and can drive 2 4.5A (max) motors. It has a bunch of exposed IO and can handle up to 20V in. It is designed for use with Adafruit's CircuitPython.
What's Project Stida?
Stida was 2231puppy's first robot. While no longer in use, the name lives on in Project Stida, 2231puppy's organization.
Why would I want it?
Well, that's simple. It's a relatively low-cost board that can be used to easily build robots that are IoT-connected. Did I mention it's super easy to program because of the awesome work at Adafruit on CircuitPython?
Great! So, where can I get one?
This is the sad part :( There is currently nowhere to purcase this board, but the source KiCad v5.1.9 files are right here in this repo. Feel free to make them yourself! I'm working on an accurate BOM.

Questions
How big is the RoboCloud PCB?
It measures 77 × 50.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RoboCloud use?
28 parts, built around the ESP32-S2-WROVER-I(4M) and NCP1117DT33T5G. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the RoboCloud KiCad files?
From the miameows/RoboCloud repository on GitHub, at the commit this page was made from: the board is RoboCloud/RoboCloud.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the RoboCloud design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
