Tomu, I'm: common questions

What microcontroller does the Tomu, I'm use?

The Tomu, I'm is built around the ICE40UP5K-UWG30, from the FPGA family.

How big is the Tomu, I'm PCB?

The Tomu, I'm measures 13 × 9.4 mm, has 4 copper layers and is 0.6 mm thick.

How many components are on the Tomu, I'm?

40 components, from 18 distinct parts. The full bill of materials is listed on this page.

Where can I download the Tomu, I'm design files?

From the theacodes/kicanvas repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Tomu, I'm design in my own project?

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

Can I test firmware for the Tomu, I'm without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug FPGA firmware against it before you order a PCB.
