- This product is borne out of an original synthesiser kit built by the now bankrupt Tech Will Save Us company. - The solderless breadboard nature of it frustrated me, and the lack of room to add a microcontroller for MIDI functionality on the breadboard made it unusable for how I would wish to use it. - Then I got bored whilst designing it, and decided I'd turn it into a Pi Pico (2(W)) dev board too. - That way I can prototype all of my projects in a single multipurpose board. - It supports a Raspberry Pi standard hat. - It supports a Raspberry Pi Pico bonnet. - The second Pi you see in the…

TWSUDiySynthKit: common questions

What microcontroller does the TWSUDiySynthKit use?

The TWSUDiySynthKit is built around the SC1633, from the RP2040/RP2350 family.

How big is the TWSUDiySynthKit PCB?

The TWSUDiySynthKit measures 198.4 × 65 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the TWSUDiySynthKit?

40 components, from 23 distinct parts. The full bill of materials is listed on this page.

Where can I download the TWSUDiySynthKit design files?

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

Can I use the TWSUDiySynthKit design in my own project?

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

Can I test firmware for the TWSUDiySynthKit 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.
