65-wkl: common questions

What microcontroller does the 65-wkl use?

The 65-wkl is built around the RP2040, from the RP2040/RP2350 family.

How big is the 65-wkl PCB?

The 65-wkl measures 288.9 × 137.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the 65-wkl?

160 components, from 20 distinct parts. The full bill of materials is listed on this page.

Where can I download the 65-wkl design files?

From the hnr-y/65-wkl-pcb repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the 65-wkl design in my own project?

Yes, under the terms of its MIT license, which hnr-y chose for the repository.

Can I test firmware for the 65-wkl 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.
