Introduction
As Bluetooth Low Energy (BLE) spreads across wearables, smart homes, and industrial sensing, TI's CC2640 has become a core choice for many Bluetooth modules. Within EBYTE's E72-2G4M series, the E72-2G4M02S2B and E72-2G4M05S1B are two BLE 5.1 low-energy modules based on the CC2640, representing two distinct positions in the BLE product line.
The Chip Core: What Is the CC2640?
The CC2640 is an ultra-low-power wireless MCU from TI's SimpleLink™ series with a dual-core architecture: an ARM Cortex-M3 main core handles application processing while a Cortex-M0 RF core manages wireless control. This division of labor keeps power low while delivering solid compute capability. Supporting the BLE 5.1 protocol, it is an ideal core for Bluetooth IoT devices.
