The Romi chassis needs to have the combined power distribution board and motor controller The Romi PDB/MC's onboard regulator NEEDS TO BE CONFIGURED TO 3.3V OUTPUT OR EVERYTHING WILL BREAK AND YOU WILL BE SAD This is accomplished by cutting the "VREG Select" trace with an exacto knife. Male headers need to be installed into the following locations (add a picture here....)

Tinyfpga raspi romi board: common questions

What microcontroller does the Tinyfpga raspi romi board use?

The Tinyfpga raspi romi board is built around the Raspberry_Pi_2_3, from the Raspberry Pi family.

How big is the Tinyfpga raspi romi board?

The Tinyfpga raspi romi board measures 103.4 × 121.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Tinyfpga raspi romi board?

71 components, from 24 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 Tinyfpga raspi romi board design files?

From the hbrc-fpga-class/hardware repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Tinyfpga raspi romi board design in my own project?

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

Can I test firmware for the Tinyfpga raspi romi board without the hardware?

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