Description

Riegel is an FPGA-based timeless computer.

In order to program the flash (or FPGA configuration SRAM) you will need to connect either a Raspberry Pi, Raspberry Pi Pico, or Müsli to the ISP header and use the ldprog tool. Riegel does not currently ship with a USB bootloader.

We highly recommend purchasing a case along with Riegel as it will help to protect the board, reduce stress on the connectors and likely increase the lifespan. You can find Riegel cases here. You can also print your own case using the design files available on Github.
