Raspberry Pi GPIO to Arduino UNO without USB

We want to control and program our Seeed Robot directly from a Raspberry Pi. The Seeed Hercules controller, which has an embedded Arduino compatible controller, does not have a built-in USB port. Therefore we want to bypass USB and talk serial TTL directly between the pins. […]
