E72-2G4M05S1G is a self-developed, small-size, SMD, bluetooth wireless module based on CC2642 of Texas Instruments.

The CC2642R integrates 352KB of in-system programmable flash memory, 88KB of buffered static RAM (SRAM) and BLE 5.2 wireless communication protocol. Because of its unique ultra-low power sensor controller, it is ideal for connecting external sensors. The analog and

digital data are collected autonomously 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 modules. We used a 24MHz industrial grade high precision low temperature drift active crystal

Since this module is a SoC module, it needs to be programmed by user before it can be used.
