An external 5V power supply is required for communication.NoteThe TTL interface of this module is a passive interface. It must be externally supplied with 5V power supply. That is, all four ports must be connected (5V, RX, TX, GND) during communication, otherwise communication cannot be performed.Operating temperature-20°C~+60°C
Package includes:
1 x TTL Serial Communication Module
