E72-2G4M02S2B is a small-size SMD RF module BLE Bluetooth wireless module independently developed based on CC2640 produced by Texas Instruments (TI)。CC2640 chip integrates 128KB intra-system programmable flash and 8KB buffer static RAM (SRAM) and different 2.4GHz wireless communication protocols. It also has a rich set of peripherals. Because of its unique ultra-low-power sensor controller, it’s ideal for connecting external sensors, and it is also suitable for autonomous collection of analog and digital data while the rest of the system is in sleep mode.Thanks to its built-in dual-core low-power processor, users can build a complete system based on their own supporting modules. We used a 24MHz industrial grade high precision low temperature drift active crystal. The module also supports secondary development. Users can write their own code to achieve the functions.
