A tiny sound card based on the Covox Speech Thing design which includes an LM386 amplifier and FT245RL chip to receive data via USB. This project is a combination of my 2 earlier projects pcb-covox-amp and pcb-usb-ft245r-parallel-adapter

A USB to parallel adapter using the FTDI FT245R chip. This is not a IEEE 1284 compliant parallel port. Just using the DB25 connector to access the data pins.
