About the ANUFS-Telemetry PCB

ANUFS-Telemetry is an open source STM32 PCB design by chithigun23, published on GitHub. It is a 4-layer board measuring 80 × 80 mm, with 157 components from 61 distinct parts.

Its main chip is the STM32H523RCT7, from the STM32 family. Other key parts include the LMR33610ADDAR, TPS2121RUXR, ASM330LHHXG1TR, TCAN337 and LM2940CT-5.0/LF01. By type, the board carries 53 capacitors, 52 resistors, 13 ICs, 10 connectors, 8 test points and 5 LEDs.

It belongs with the rf & radio designs in this gallery.

From the project

To use custom hardware to measure parameters and dynamics of an ICE Formula SAE car.

STM32H5-based data-logging and telemetry module for the ANUFS vehicle. It sits on two of the car's CAN buses, fuses IMU + GNSS data with bus traffic, logs everything to a microSD card, drives onboard status LEDs, and exposes USB-C for bench debug.

- Power - the board runs from the vehicle's 12–36V harness input (J1), fused and surge/reverse-polarity protected before reaching U2 (TPS2121), which arbitrates between that battery feed and USB-C bus power so the board can run on the bench without the car. The muxed rail (VIN) feeds two independent regulators: U1 (LMR33610) bucks it to the +3.3V…

ANUFS-Telemetry: common questions

What microcontroller does the ANUFS-Telemetry use?

The ANUFS-Telemetry is built around the STM32H523RCT7, from the STM32 family.

How big is the ANUFS-Telemetry PCB?

The ANUFS-Telemetry measures 80 × 80 mm, has 4 copper layers and is 1.5962 mm thick.

How many components are on the ANUFS-Telemetry?

157 components, from 61 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 ANUFS-Telemetry design files?

From the chithigun23/ANUFS-Telemetry 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 ANUFS-Telemetry design in my own project?

The repository has no license, so all rights stay with chithigun23. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the ANUFS-Telemetry without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
