From the project
EE education board for the GateMate FPGA evaluation board E1
The gm-study-e1 board is an application module board for the GateMate FPGA evaluation board E1, made by Cologne Chip. It connects to the evaluation board through all six GPIO headers, and its main feature are the input/output components similar to popular FPGA trainer boards used for classroom teaching in electrical engineering and embedded systems education (e.g. Digilent Basys or Altera DE10-lite). These boards were created after successful design tests of the gm-proto-e1 boards. The "gm-proto-e1" boards have only a few basic I/O, but provide a 2.54mm prototyping area for experimentation…
