LM780 Bluetooth Class 2 Module On-Board Antenna

The LM780 Bluetooth Class 2 Module On-Board Antenna is a an integrated module comes with LM’s own tried and tested SPP Stack in either BT2.1 EDR or BT2.0 EDR standards. Its Class 2 antenna will support distances up to 25m while offering a low power consumption, while in sleep mode its output is 0.9mA, and at connection while passing data still only 19mA. 

It supports UART & SPI interfaces and accepts a wide voltage input range of between 3.0v to 5.5v, with a footprint of just 15.20 mm x 26.92 mm x 2.0 mm and operates within -20◦c to +70◦c working temperature range it offers a compact solution.

LM780 Bluetooth Class 2 Module On-Board Antenna SMT Solution. 

The Bluetooth Class 2 Module is a surface mount module that has an RF Shield and holds FCC and RTT&E CE Certification with full compliance of RoHs standards.

Ready and easy to design in this total solution is available with full support from LM Technologies who offer a free Design In service, at request we can also alter firmware commands helping integrate our module into a current solution.

The LM780 Bluetooth Class 2 Module On-Board Antenna is available in low volume trays or high volume tape and reel packaging and has been aimed at the most competitive edge of the market.
