ProtoB: common questions

What microcontroller does the ProtoB use?

The ProtoB is built around the RP2040, from the RP2040/RP2350 family.

How big is the ProtoB PCB?

The ProtoB measures 50 × 30 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the ProtoB?

54 components, from 20 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 ProtoB design files?

From the X65/schematic 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 ProtoB design in my own project?

The repository has no license, so all rights stay with X65. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the ProtoB 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.
