SPECIFICATIONS

Brand Name: Aideepen

Choice: yes

Condition: New

High-concerned chemical: none

Origin: Mainland China

Type: Module

Features:

1. Supports USB to RS485/RS232 communication (switchable via DIP switch).

2. Utilizes the new CH343G chip for plug-and-play operation, compatible with Windows, macOS, Linux, and other systems.

3. On-board TVS (Transient Voltage Suppressor) effectively suppresses surge voltages and transient spikes in the circuit, providing lightning and static protection.

4. Onboard self-resetting fuse and protection diode ensure stable current and voltage output, prevent overcurrent/overvoltage, and enhance surge resistance.

5. Three onboard LED indicators facilitate monitoring of power and signal transmission status.
