The CaptainDMA 75T is a variant of Artix-7 75T DMA boards sold by CaptainDMA and their resellers. It comes equipped with a kill switch and two USB-C ports. One port is a USB 3.1 port driven by an FTDI USB FIFO chip. The update port is a CH347; an alternative chip to the standard FTDI JTAG UART silicon.
The CH347 makes flashing this device tricky. You need to use vendor supplied software and a custom compiled OpenOCD variant. It made working with this board particularly challenging.
When I did manage to figure out flashing, this board smashed my 35T's performance profile. Easily 20% faster than any other device I had tried up to that point.
