The HM-10 Bluetooth module combines the Texas Instruments CC2541 Chipset with the necessary components to get started with BLE development right away. TTL-level and 5 V tolerant, the module has an onboard voltage regulator. The Bluetooth-SoC can be accessed through a UART interface and can be configured using AT-Commands. It complies with the Bluetooth 4.0 standard and can be used to connect an Arduino or microcontroller to an Android or iOS device. This module is compatible with the HC-05, HC-06, and HC-07 devices.
