AJMRTC CH9142 Micro Bluetooth Module BLEDTPTBANT, BLE5.3 Serial Port Transparent Transmission Dual UART Wireless Module, AT Command Configurable for IoT Sensor MCU DIY Electronic Projects

AJMRTC CH9142 BLEDTPTBANT micro Bluetooth transparent transmission module adopts CH9142 chip solution for BLE5.3 lowenergy wireless serial communication. It converts Bluetooth signals into UART serial data to achieve transparent bidirectional data transmission, helping users quickly realize wireless transformation of serial devices without heavy firmware development. This module provides two independent UART channels, which can run with separate configurations to connect two different serial peripherals at the same time. Users can adjust working mode, Bluetooth name, baud rate and transmit power through serialport AT commands. The onboard antenna ensures reliable receiving and transmitting performance. It works well paired with MCU, sensors and industrial serial instruments, supports connection across Windows, Linux, Android and iOS platforms. The miniature PCB form factor facilitates embedding inside limitedspace hardware. Pay attention to powersupply voltage requirements during usage; confirm serialport baudrate consistency between module and connected device to avoid communication failure.
