Core software repository for the Tennessee Valley Stellar Corporation
This repository is the principal codebase for the Tennessee Valley Stellar Corporation. We are a community-scale space agency in east Tennessee dedicated to the open development of technologies enabling the public use of space.
There are three main sections to the repository. The most active development at the moment is taking place in the hal and the electronics directories. The hal directory contains the Hardware Abstraction Layer. The electronics directory holds our PCB design work. The rest of the repository (the third section) consists of older code that is in need of…

Magnetorquer Control Board: common questions
What microcontroller does the Magnetorquer Control Board use?
The Magnetorquer Control Board is built around the C192722, from the STM32 family.
How big is the Magnetorquer Control Board?
The Magnetorquer Control Board measures 82.5 × 82.5 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Magnetorquer Control Board?
92 components, from 26 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Magnetorquer Control Board design files?
From the stellarcorp/tvsc repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Magnetorquer Control Board design in my own project?
