CH9141 Bluetooth LE Transparent UART Module

Now available from PMD Way are these compact and useful CH9141 Bluetooth LE Transparent UART Modules. 

They can easily be used as a Bluetooth UART data passthrough, so you can access your microcontroller-based projects using the UART via Bluetooth.

Specifications:

• Supports broadcast mode, master mode and slave mode
• Supports serial port AT configuration and Bluetooth transmission configuration
• Provides Bluetooth virtual serial port driver on computer
• Compatible with existing serial port software and tools, without secondary development
• Supports Bluetooth host connection of Windows/Linux/Android/iOS and other systems
