Note: This listing is for a bare PCB only, intended for DIY assembly.

This listing is for those keen and adventurous tinkerers that are up for a challenge and want a bare PCB to try hand assembling one of these themselves. As a reward for your hard work you'll be in possession of an OrangeCrab with a Blue PCB, these will not be sold assembled.

In addition to this PCB you will need to order the parts separately, along with a solder paste stencil.

What is it?

The OrangeCrab is an electronics development board. It is FPGA based featuring an ECP5 from Lattice. The board follows the slim feather board specification from Adafruit. The FPGA is compatible with all open source toolchains and is perfect for experimenting with RISC-V cores.

This updated version (r0.2.1) has the following features:

• 100% software and pin compatible
• Castellated edge connectors
• USB-C connector.

Why did you make it?

There aren't many FPGA boards available that make use of the ECP5, but here are some distinct features that set this board apart:

• Small Compact size (Take it anywhere!)
• Direct USB connection to the FPGA (Operate as a DFU, MSC, CDC, or composite device!)
• On-board DDR3 Memory (1Gbit!)
• It's Blue!

What makes it special?

• Lattice ECP5-25F FPGA (Part # LFE5U-25F-8MG285C)
• DDR3L Memory 128 Mbytes (1Gbit) 64M x16
• Full-speed (12Mbit) USB with a direct connection to the FPGA
• 16Mbytes QSPI FLASH
• MicroSD card support
• Brilliant Blue colour!
