New FPGA development board from Newark

26 May 2021

Newark, a division of Avnet, has expanded its single board computer development kits with the OrangeCrab r0.2 open-source field programmable gate array (FPGA) from Good Stuff Department.

The OrangeCrab FPGA combines a compact Adafruit Feather form factor with the power of larger FPGA development boards. The FPGA is based on the Lattice RPC5 FPGA that is compatible with open-source toolchain and can be experimented with RISC-V and other softcore system-on-chips.

The CircuitPython can be ported to the OrangeCrab for hosting the interpreter and developers can target the FPGA itself with gateware synthesized HDL as well as ECP5 to run RISC-V softcore and LiteX project to increase flexibility and capability.

Other features include:

  • Lattice Semiconductor EPC5 FPGA with 25K LUT elements, 10-pin FPGA programming header and microSD socket.
  • Up to 8 Gbit DDR3 onboard system memory and storage of 128 or 512 Mbit QSPI flash memory.
  • Open-source USB bootloader to connect more than FPGA’s native USB interface to upload code and access the memories over MSD.
  • DCDC for main supplies, a battery charger chip, a LiPo battery connector and 48 MHz oscillator.
