About the Par2Ser PCB
Par2Ser is an open source PCB design by jbilander, published on GitHub under the CC-BY-SA-4.0 license. It is a 4-layer board measuring 47 × 50 mm, with 41 components from 28 distinct parts.
Other key parts include the LC4064V-75TN48C, FT240XS-R and TLV75533PDBVR. By type, the board carries 17 resistors, 13 capacitors, 4 diodes, 3 ICs, 3 connectors and 1 inductor.
It belongs with the retro computing and usb & debug tools designs in this gallery.
From the project
A device that bridges the Amiga parallel port to a USB FIFO (FT240X)
A serial.device-compatible Amiga driver that bridges the parallel port to a USB FIFO (FT240X) via Niklas Ekström's 2E parallel-adapter protocol, so unmodified comms programs (c-kermit, NComm, …) can set line par2ser.device.
The hardware side is a small board built around a Lattice LC4064V-75TN48C CPLD that speaks the 2E protocol to the Amiga and presents the bytes to an FT240X USB FIFO. The PC sees a standard USB serial port (VCP).
