The OrangeCrab is a feather form factor electronics development board. For the Lattice ECP5 FPGA. 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. There aren't many FPGA boards available that make use of the ECP5, but here are some distinct features that set this board apart:
|Lattice ECP5-25F FPGA||Lattice ECP5-85F FPGA|
Unlike traditional FPGA development boards, this board is small enough to carry in your pocket and function as a prototyping ground for custom SoC designs.
If you are not familiar with the feather format, you might be surprised by the size of this board. The Feather format has dimensions of: 22.86 x 50.8mm (0.9" x 2.0")
For reference this is the board pictured next to some standard ISO/IEC 7810 ID-1 cards.
