Bb pcb v1: common questions

What microcontroller does the Bb pcb v1 use?

The Bb pcb v1 is built around the Raspberry_Pi_Pico, from the RP2040/RP2350 family.

How big is the Bb pcb v1?

The Bb pcb v1 measures 347.7 × 119.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Bb pcb v1?

216 components, from 19 distinct parts. The full bill of materials is listed on this page.

Where can I download the Bb pcb v1 design files?

From the derEchteJan/keyboards repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Bb pcb v1 design in my own project?

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

Can I test firmware for the Bb pcb v1 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.
