Communication Interface TTL interface Size 73.7 x 30 x 14.3mm Power supply The single-phase power frequency grid power supply is supplied to the main circuit through the RC capacitor, and the TTL output communication interface is isolated from the main circuit optocoupler and is a passive output. An external 5V power supply is required for communication. Note The 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
