The LM780 from LM Technologies is a Bluetooth serial data module featuring a class 2 radio with an integrated chip antenna. It is ideal for short-range wireless connectivity for embedded applications. The LM780 offers up to 25m in open space from a small device, with low power consumption.
With a CSR Bluecore 4 (BC04) chip and its centre, the LM780 module and supports Bluetooth SPP (Serial Port Profile) firmware as default.
Use the LM780 in standalone mode (without a host to drive it) and interface via UART to embedded microcontrollers.
