About the Firmware tester board

Firmware tester board is an open source AVR/Arduino PCB design by olin-electric-motorsports, published on GitHub. It is a 2-layer board measuring 49.9 × 75.4 mm, with 58 components from 23 distinct parts.

Its main chip is the ATMEGA16M1-AU-ND, from the AVR/Arduino family. Other key parts include the AP7370-50W5-7DICT-ND and MCP2561-E/SN-ND. By type, the board carries 26 resistors, 14 connectors, 7 capacitors, 3 ICs, 3 test points and 2 diodes.

From the project

OEM Monorepo

The projects/ directory will house projects that are under active and volatile development. This will include things like advanced research projects that won't make it onto the vehicle during the current season, as well as projects that are parallel to the car, like the HIL system.

Once a car-related project has matured enough, it will be moved into the vehicle/ directory, where development may continue to integrate it into the vehicle of the season.

Firmware tester board: common questions

What microcontroller does the Firmware tester board use?

The Firmware tester board is built around the ATMEGA16M1-AU-ND, from the AVR/Arduino family.

How big is the Firmware tester board?

The Firmware tester board measures 49.9 × 75.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Firmware tester board?

58 components, from 23 distinct parts. The full bill of materials is listed on this page.

Where can I download the Firmware tester board design files?

From the olin-electric-motorsports/olin-electric-motorsports repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Firmware tester board design in my own project?

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

Can I test firmware for the Firmware tester board without the hardware?

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