Orangecrab hardware: common questions

What microcontroller does the Orangecrab hardware use?

The Orangecrab hardware is built around the ECP5U25, from the FPGA family.

How big is the Orangecrab hardware PCB?

The Orangecrab hardware measures 50.8 × 22.9 mm, has 6 copper layers and is 1.6 mm thick.

How many components are on the Orangecrab hardware?

141 components, from 46 distinct parts. The full bill of materials is listed on this page.

Where can I download the Orangecrab hardware design files?

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

Can I use the Orangecrab hardware design in my own project?

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

Can I test firmware for the Orangecrab hardware 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.
