This is the repo for my TVC rocket that took two years to develop.
This is the last revision that actually worked. At the end of my 8th-grade year, there were many other iterations, but I have lost the documentation for those.

The goal of this was to make a thrust vector controlled rocket that can stabilize itself on the way up. This goal ended up being completely successful. Demo: https://drive.google.com/file/d/10EWHrPkHGs0dUHyr1Sujefc27muy-WCw/view?usp=sharing

Questions
How big is the RAM R2 PCB?
It measures 45.3 × 81 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RAM R2 use?
65 parts, built around the ESP32-S3-WROOM-1-N8, BMP390L, TPS565208DDC and W25Q16JVSSIQ. 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 RAM R2 KiCad files?
From the nimishcoder1232/TVC-Rocket repository on GitHub, at the commit this page was made from: the board is PCB/RAM R2.kicad_pcb and its schematic PCB/RAM R2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the RAM R2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask nimishcoder1232 before reusing the design.
