README
README.mdANUFS Telemetry
Data-logging and telemetry module for the ANUFS vehicle: an STM32H523 board that listens on two CAN buses, fuses dual-antenna GNSS and an IMU with them, and logs everything to two microSD cards.
| Folder | What is in it | Start here |
|---|---|---|
| hardware/ | KiCad project, fabrication files, BOM, power budget, RF analysis | hardware/README.md |
| software/ | Rust firmware crates, host tools and diagrams | software/README.md |
Where things stand
- Hardware: boards are ordered and will be assembled by hand. Fit R10 as 73.2k (the BOM is up to date). Fit J12 as the SWD header until the Tag-Connect cable arrives.
- Software: every logic crate and host tool is written and tested on the PC (332 tests), and the firmware (a bring-up self-test and the logger) builds for the chip. Nothing has run on the board yet; assembly is in hardware/ASSEMBLY.md and the bring-up order is in software/README.md.
- Waiting on you: the MoTeC CAN configuration (bit rate and message layouts), and a debug probe.

Questions
How big is the Telemetry PCB?
It measures 80 × 80 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Telemetry use?
159 parts, built around the STM32H523RCT7, LC29HEAMD, TCAN337D and LM2940CT-5.0/LF01. 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 Telemetry KiCad files?
From the chithigun23/ANUFS-Telemetry repository on GitHub, at the commit this page was made from: the board is hardware/telemetry-kicad/telemetry.kicad_pcb and its schematic hardware/telemetry-kicad/telemetry.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Telemetry design in my own project?
Its repository states no licence, so its author keeps all rights: ask chithigun23 before reusing the design.
