BrisbaneSilicon ELM11-Feather is a “microcontroller” board based on a Gowin GW1NR FPGA that is natively programmable in Lua, C, SystemVerilog, and VHDL.Compatible with the Adafruit Feather form factor, the board features GPIO headers, a built-in debugger, a USB-C port for power and programming, and a 2-pin header for a LiPo battery. The company calls it a microcontroller board because the FPGA runs a PicoRV32 MCU softcore at up to 75 MHz with 1MB RAM and 8MB flash, programmable with Lua, and the user can also customize hardware layers with RTL code using the remaining FPGA fabric.ELM11-Feather specifications:
FPGA – Gowin GW1NR-LV9 FPGA from the GW1NR-9 family
8K LUTs
8,640 logical units (LUTs)
6,480 flip-flop
