BXB Devboard: common questions

What microcontroller does the BXB Devboard use?

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

How big is the BXB Devboard PCB?

The BXB Devboard measures 21 × 51 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the BXB Devboard?

33 components, from 16 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 BXB Devboard design files?

From the Az154za/BXB_Devboard 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 BXB Devboard design in my own project?

The repository has no license, so all rights stay with Az154za. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the BXB Devboard 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.
