UB232B1 UB485A1 UBTTLC1 CH343 High-Speed USB to RS232, RS485 or TTL Serial Converter Debug Adapter for Arduino, Raspberry Pi and ESP32

Design intention: There are many USB to RS485/232/TTL products on the market. However, we found that there are few products with strong anti-interference and fast speed. Therefore, ELETECHSUP decided to break the convention and use the high-speed USB to serial port chip CH343 plus input and output protection circuit to design a product with both high speed and stability.
