On-Board-Computer: common questions

What microcontroller does the On-Board-Computer use?

The On-Board-Computer is built around the RASPBERRY_PI_PICO, from the RP2040/RP2350 family.

How big is the On-Board-Computer?

The On-Board-Computer measures 90.1 × 95.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the On-Board-Computer?

12 components, from 12 distinct parts. The full bill of materials is listed on this page.

Where can I download the On-Board-Computer design files?

From the prasannan-robots/On-Board-Computer repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the On-Board-Computer design in my own project?

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

Can I test firmware for the On-Board-Computer without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
