This product is a Bluetooth module BLE 4.0 UART without adapter, low energy with serial transceiver.
Logic level conversion circuit. No external level of 5V is needed to become a 3.3V level.
The power input port is protected against the anti-circuit, to avoid the inverted accidental power plug, which leads to the module burn
HM-10, Bluetooth module HM-11 series using IT chip CC2540 / 2541, configuration 256Kb space, support
You can change the paper (master and slave mode) and the baud rate, the device name, the pairing of the password and other parameters, convenient and flexible.
