Stlxy 6N137 optocoupler chip bidirectional UART communication protocol serial port isolation module 600-250K baud rate

EU LVD Voltage : Low voltage: Below 50Vac or 75Vdc High-concerned chemical : none Model Number : 6N137 Brand Name : Stlxy Origin : Mainland China

Description: Two 6N137 optocouplers are used to realize TTL serial isolated two-way communication. The speed of 6N137 is up to 10M, which is suitable for serial communication with common baud rate of 600~250K. The size of the circuit board is 52*25mm.

Note: This module only supports TTL serial ports, that is, 3.3V or 5V single-chip microcomputers, or the serial port isolation of microprocessors. 232-level serial ports cannot be used directly. The computer's native serial port cannot be used.
