Sweet16v2: common questions

What microcontroller does the Sweet16v2 use?

The Sweet16v2 is built around the RP2040, from the RP2040/RP2350 family.

How big is the Sweet16v2 PCB?

The Sweet16v2 measures 76.2 × 76.2 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Sweet16v2?

56 components, from 7 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 Sweet16v2 design files?

From the 1upkeyboards/PCBs 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 Sweet16v2 design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Sweet16v2 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.
