Half monty-2: common questions

What microcontroller does the Half monty-2 use?

The Half monty-2 is built around the RP2040-Zero, from the RP2040/RP2350 family.

How big is the Half monty-2 PCB?

The Half monty-2 measures 47.7 × 45.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Half monty-2?

50 components, from 31 distinct parts. The full bill of materials is listed on this page.

Where can I download the Half monty-2 design files?

From the neilpstevenson/monty-mouse-mini repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Half monty-2 design in my own project?

Yes, under the terms of its MIT license, which neilpstevenson chose for the repository.

Can I test firmware for the Half monty-2 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.
