Kolibri FPGA Dongle

Description

Kolibri is a USB dongle with an FPGA and PMOD connector. It has an RP2040 MCU that allows the FPGA SRAM and onboard flash to be programmed over the USB connection using ldprog. The USB connection also acts as a USB-UART bridge to the FPGA.

Each order includes one Kolibri (two are pictured in order to show both sides).
