Introduction

E72-2G4M02S2B is a compact SMD RF module — a BLE Bluetooth wireless module based on the CC2640. The CC2640 integrates 128KB in-system programmable flash memory and 8KB buffered SRAM, supports various 2.4GHz wireless communication protocols, and offers a rich set of peripherals. Its unique ultra-low-power sensor controller is well-suited for interfacing with external sensors and for autonomously acquiring analog and digital data while the rest of the system remains in sleep mode. Thanks to the built-in dual-core low-power processor, users can build complete systems on top of the supported module. The module features a 24MHz high-precision, low-temperature-drift active crystal oscillator. It also supports secondary development, allowing users to write their own code to implement custom functionality.
