The µUSB-PA5-II is a compact USB-to-serial TTL UART bridge based on the SiLabs CP2104 IC. It connects to a PC via a Mini-B USB connector and provides serial data at baud rates up to 3 Mbps with flow control support. The main 5-pin interface uses a standard 2.54 mm (0.1") pitch female header.

RX and TX signals are both 3.3 V and 5 V tolerant. Designed primarily for programming 4D Systems display modules, it is also useful as a general-purpose USB-to-serial adapter for any TTL UART device.
