The EH-MC10 is a Bluetooth low power module designed for low power sensors and data transmission based on the CSR1010 chip. It integrates all the features needed for Bluetooth Smart applications, including Bluetooth radio, software stack, and GATT-based specifications.

The EH-MC10 module can also host enduser applications, which means that no external microcontroller is required for size or price constrained devices. In addition, it has a flexible hardware interface for connecting different peripherals and sensors, supports simple display functions, and can be powered directly from a standard 3V coin cell or a pair of AAA batteries. In the lowest power sleep mode, it consumes only 500 nA and can be woken up in a few hundred microseconds.

The latest SDK can support CSRMesh functionality and can be selfnetworked for control of more than 65,000 nodes. In addition, the module also supports master-slave mode, passthrough mode, WeChat communication protocol, etc. It is mainly used in smart hardware, medical equipment, industrial control, Beacon, etc.

EH-MC10 contains two types: selfcontained ceramic antenna and with external U.FL head (EM-MC10B).
