Product introduction


EH-MC13 is a Bluetooth low power module based on Realtek 8762 chip designed for low power sensor and data transmission. It integrates all the features required for Bluetooth 5.0 applications, including Bluetooth radio, software stack and GATT based specifications, enabling large data 2M bps transmission, long range transmission, and stable small data transmission between modules and modules over 200 meters in open conditions.

The EH-MC13 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 by standard 3V coin cell batteries or a pair of AAA batteries. In the lowest power sleep mode, it consumes only 450 nA and can be woken up in a few hundred microseconds.

The latest SDK can support SIGMesh function, which can be self-organized to control more than 65,000 nodes. In addition, the module also supports masterslave mode, transmissive mode protocols, etc. Mainly used in smart hardware, medical equipment, industrial control, Beacon, etc. The module supports Ali's Tmall Genie ecosystem and is an official Ali certified module, which has been used in smart lights, sockets, switches, heaters, fans, body fat scales, etc. It is a low cost and high performance module.
