UT-8851 is a USB/TTL converter, which is compatible with USB and TTL standards without extra power. It can convert single USB signal into TTL signal, and the TTL end is connected through the terminal block. The converter is equipped with zero-delay automatic transceiver conversion, and the unique I/O circuit automatically controls the direction of data flow without any handshake signal (such as RTS, DTR, etc.). TTL mode conversion is realized without jumper setting, plug and play. This ensure that it is suitable for all existing communication software and interface hardware.
UT-8851 can provide reliable connection for point-to-point communication. The baud rate is 300-921,600 BPS. It is with power indicator and data flow indicator, and supports USB to TTL communication.
