1. On-board resettable fuse and transient suppression diode, anti-overcurrent and overvoltage, anti-backflow, anti-static, improve shock resistance, stable and safe communication
2. On-board IO protection circuit, anti-surge, stable and safe communication
3. The onboard TTL serial port 3.3V and 5V level conversion circuit can switch the TTL communication level
4. There are 3 LED indicators on the board, which is convenient to check the status of power supply and signal sending and receiving
5. DC simple bull socket interface, smooth plug and unplug, sturdy and reliable, prevent reverse connection
