Owing to the trend that is driving the success of the Feather form factor for boards is the change in the methodology and languages in which boards are now being programmed. It is quite certain that the maker market is in its transition state and it is hard to tell what the next interesting thing disrupting the board ecosystem is, but with the availability of open-source toolchains for FPGA chips, the age of FPGA has come to stay with a number of FPGA boards starting to appear. So, if you are thinking of getting started with using an FPGA board, this could be a good entry point.

Among the new range of FPGA boards beginning to penetrate the maker market is the new OrangeCrab board from Greg Davill. The feather-compatible board modeled and developed by Davill is capable of running a soft RISC-V Core and has a fully open-source toolchain and according to the tweet by Davil, “

…the USB lines re hooked directly to the ECP5. So it should be possible to port [the CircuitPython] implementation done on Fomu over to this board”.

It is based on a Lattice Semi ECP5 FPGA, with 118 available I/O pins and up to about 8Gbit of DDR3 memory that takes more than 50 pins on the boards but still leaves enough for the board to be pin-compatible with the feather.

The board supports a LiPo battery connector, 128Mbit of QSPI Flash memory, a micro USB connector that allows for a direct UBS connection to the FPGA at full speed as well as a micro SD card socket.

The OrangeCrab board is not available for sale yet and of course without any pricing information, but more about its schematics and Gerber files can be found in the project’s GitHub repository.

You can follow Davill’s Twitter thread for some detailed tweets about the evolution of the board and exceptionally good images.
