Serial Port Bluetooth with Baseboard (Master) -Arduino Compatible

Industrial serial port bluetooth, Drop-in replacement for wired serial connections, transparent usage. You can use it simply for a serial port replacement to establish connection between MCU and GPS, PC to your embedded project and etc.

The default serial port is set to [***0, N, 8, 1]
Matching password: ***0
Support the AT commands to modify baud rate, device name, matching password
Support modifying baud rate device name and matching password via AT commands
Support baud: ***0~******0.
From picture below, it has DIP pins, which is the difference made by baseboard.
