MioLink: common questions

What microcontroller does the MioLink use?

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

How big is the MioLink PCB?

The MioLink measures 53 × 42 mm, has 4 copper layers and is 1.6554 mm thick.

How many components are on the MioLink?

92 components, from 36 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 MioLink design files?

From the Misaka0x2730/MioLink 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 MioLink design in my own project?

Yes, under the terms of its GPL-3.0 license, which Misaka0x2730 chose for the repository.

Can I test firmware for the MioLink 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.
