Signal conversion circuit with 6 functions USB UART RS232 RS485 includes the following ICs: CP2102, MAX232, MAX485 is designed to be able to convert the following communication signals:
USB <-> UART TTL
USB <-> RS232
USB <-> RS485
UART TTL <-> RS232
UART TTL <-> RS485
RS232 <-> RS485
Versatile and compact circuit, using high-quality signal level conversion ICs, setting up signal level conversion for communication via Jumper is very easy.
Driver for IC USB UART CP2102.
