Sgh60: common questions

What microcontroller does the Sgh60 use?

The Sgh60 is built around the RP2040-Zero_reverse_for_sgh60, from the RP2040/RP2350 family.

How big is the Sgh60 PCB?

The Sgh60 measures 285 × 94.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Sgh60?

155 components, from 9 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 Sgh60 design files?

From the sago35/tinygo-keyboard 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 Sgh60 design in my own project?

Yes, under the terms of its MIT license, which sago35 chose for the repository.

Can I test firmware for the Sgh60 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.
