Variants

There are several variants of Fomu hardware.

Hacker version

• The hacker version is designed for people who are up to the challenge of building their own board.
• It has a simpler PCB which makes it cheaper to produce in a small quantities.
• However, it uses a non-standard footprint for the FPGA WSCP which reduces yield and long term reliability making it unsuitable for mass production.
• It's also missing some decoupling capacitors and power filters, which may impact stability
• Only two SPI wires are connected, meaning it cannot handle quad SPI

Production version EVT

• This is a prototype board designed to fit on top of a Raspberry Pi
• It does not fit on a USB port
• The large size makes it easier to debug
• The schematic serves as the basis for future production boards
• It uses 6/6 design rules, making it very easy to produce

Production version PVT

• You get a production version if you order from Sean 'xobs' Cross through or after the Crowd Supply campaign.
