AJMRTC HM10 BLE 4.0 Bluetooth Module, MasterSlave Integrated UART Serial Wireless Transceiver Module with CC2541 Chip, AT Command Configurable for Arduino MCU Embedded DIY Electronic Projects

AJMRTC HM10 Bluetooth 4.0 BLE module is a masterslave integrated serial wireless transceiver module based on CC2541 chip. Working on 2.4 GHz ISM band, it supports both master central mode and slave peripheral mode, role switching can be completed by sending AT commands without hardware modification. It realizes UART serialport transparent transmission, users do not need to develop complex Bluetooth protocol stack, which greatly simplifies wireless transformation for singlechip microcontroller devices. Multiple working parameters can be configured through AT commands, including baud rate, device name, pairing password, broadcast cycle and connection parameters to adapt different project requirements. The lowenergy BLE architecture supports sleep powersaving mode, suitable for batterydriven smallsize equipment. Equipped with onboard PCB antenna, it provides stable shortrange wireless connection. Widely applied in Arduino development, sensor data transmission, wireless remote control, smart home prototype and other embedded DIY scenarios. Operating voltage is 2.5V3.3V DC. Please avoid supplying 5V voltage directly to prevent module burnout. Only Bluetooth module is included in package, MCU and other matching accessories are not provided.
