Product introduction

EH-ES201 is a SiP BLE Module, low-power Bluetooth® 5 module. The built-in Nordic 52805 ultra-low power Bluetooth chip features ultra-small size and powerful functionality. The EH-ES201 comes with high performance built-in antenna, which can connect up to 60m in open environment without external antenna. customers to achieve ultra-miniaturized products. The ES201 module can also support external antenna to meet the requirements of antenna performance and layout for different applications.

The module can be powered directly by standard 3V coin cell batteries or AAA batteries. In the lowest power consumption sleep mode, it consumes less than 1uA of current and will wake up in a few hundred microseconds.

After purchasing EH-ES201, we will provide free technical support for IOS system APP or Android system APP.
