Lebkuchen is an FPGA computer based on the GateMate A1.
This repo contains schematics, PCB layouts, pinouts, a 3D-printable case, example gateware and documentation.
Find more information on the Lebkuchen product page.
Lebkuchen can be programmed over USB-C or by copying gateware to a MicroSD card (not yet implemented). The FPGA is configured by the onboard RP2040, which can load the configuration from onboard flash, a FAT-formatted MicroSD card or over the USB-JTAG bridge.
Program the FPGA configuration SRAM:
openFPGALoader -c dirtyJtag image.bit
| Pin | Signal |
