Out of stock

SKU: LD-KROTE Categories: , , ,


Kröte is a minimal FPGA development board. The FPGA can be programmed with gateware built using open-source FPGA development tools.

We recommend using either a Raspberry Pi, Raspberry Pi Pico, Werkzeug or Müsli to program the flash and SRAM with the ldprog tool.
