T61 PiPico Scanner: common questions

What microcontroller does the T61 PiPico Scanner use?

The T61 PiPico Scanner is built around the Pico, from the RP2040/RP2350 family.

How big is the T61 PiPico Scanner PCB?

The T61 PiPico Scanner measures 60 × 45 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the T61 PiPico Scanner?

20 components, from 12 distinct parts. The full bill of materials is listed on this page.

Where can I download the T61 PiPico Scanner design files?

From the sly547/T61_PiPico_Scanner repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the T61 PiPico Scanner design in my own project?

The repository has no license, so all rights stay with sly547. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the T61 PiPico Scanner 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.
