diymore DC 3.3V/5V TTL to RS485 Interconversion Module Serial Level Conversion Board Serial Hardware Auto Flow Control

diymore. Features: 1. Original 74HC14 SP485 chip to ensure stable transmission: the TTL to RS485 converter module uses a combination of high-quality 74HC14 and SP485 chips to provide excellent signal conversion performance. 2. Lightning gas discharge tube, enhance anti-interference ability: built-in lightning gas discharge tube, can effectively absorb and discharge atmospheric overvoltage, to prevent lightning strikes and other emergencies on the equipment caused by the damage. 3. Three transient suppression diodes TVS, comprehensive protection circuit: equipped with three sets of transient suppression diodes TVS), used to prevent electrostatic discharge ESD), induced lightning strikes and other transient overvoltage events on the circuit. 4. Thermal fuse for overcurrent protection: Thermal fuse for overcurrent protection, when the current exceeds the safety threshold, the fuse will quickly blow, cutting off the power supply, to avoid fires and equipment damage due to short-circuits or
