BLE5101 : CE-RED & FCC ID Certified BLE Module BLE 5.1

BLE5101 is a BLE module based on BLE 5.1 Protocol, coexistence of master and slave roles, small size, low power consumption, and the working signal frequency band is 2.4GHz.
The BLE5101 module is developed by Shenzhen NiceRF Wireless Technology Co., Ltd. The module supports the coexistence of master and slave roles, can connect to the master and slave at the same time, and can flexibly set the number of master and slave connections, and can support up to 20 connections. Maximum support for data transmission at 115200bps baud rate. The module uses AT commands to set parameters, and the operation is simple and easy to use. In addition, BLE5101 also has BLE Mesh function, which can be used with other modules to achieve mesh networking. Modules can be widely used in smart wear, smart home, automobiles, lighting, smart automation data collection, smart control, wireless sensing, electronic tags and other scenarios.
BLE5101 strictly uses lead-free technology for production and testing, and meets RoHS and Reach standards.
BLE module BLE5101 has obtained CE-RED and FCC ID certification.
