Supports standard TTL and low-voltage TTL, supports 5V/3.3V/2.5V/1.8V chip burning and TTL communication
The power supply VCC and signal levels (RX, TX, CTS, RTS, DTR, DSR, DCD) both support switching between 5V/3.3V/2.5V/1.8V levels
Adopting chip conversion scheme, non transistor scheme, low level is 0V (transistor scheme cannot reach 0V due to conduction voltage drop)
The USB port is equipped with electrostatic protection and current protection, while the signal interfaces RX, TX, CTS, and RTS ports are equipped with current protection and ESD protection
Onboard power indicator light and various signal indicator lights (RX, TX, CTS, RTS) can more conveniently detect the working status of the module
