HM-10 Bluetooth Low Energy Module with Level-Shifting for Arduino

HM-10 BLE (Bluetooth Low Energy) Module based on CC2541 chipset.

This module makes it easy and safe to use with Arduino. It has onboard voltage regulator to power the module, and a level-shifting chip to guarantee proper signal levels to/from Arduino. No need to externally convert 5V level to 3.3V level.

Also has Power input port with anti-reverse circuit. This avoids accidental power plugging, resulting in module burnout problems.

HM-10 sub-module is supplied as pre-soldered on carrier board. The carrier board has headers for easy connection and prototyping needs.
