The µUSB-PA5 is a compact USB-to-Serial TTL UART bridge based on the FTDI FT232RQ. It connects to your PC via a Mini-B USB connector and provides serial communication at baud rates up to 3 Mbps — designed primarily for programming and communicating with 4D Systems displays and controllers.

The 5-pin 2.54 mm female header plugs directly into most 4D Systems modules. RX and TX signals are both 3.3 V and 5 V tolerant. Additional flow control and signal pins are available on through-hole pads along each side of the PCB.

Key Features

  • FTDI FT232RQ – Reliable USB-to-Serial bridge IC
