LM072 Bluetooth Class 1 Module

The LM072 Bluetooth Class 1 Module is a an integrated module which runs LM’s own tried and tested BT2.1 or BT2.0 CSR Stack Firmware. With an 18dBm output from the RF terminal this powerful Bluetooth Class 1 Module will cover distances beyond 100m when coupled with a well-tuned antenna circuit. LM Technologies have used this module as their core within the LM048, LM058 Bluetooth serial adapters and with our LM400 and LM410 Plug & play pin modules.It has therefore been certified many times within a product as well as holding SIG certification for non-antenna based Bluetooth Class 1 Module and its has FCC & RTT&E CE certification and offers full compliance with RoHs.

LM072 Bluetooth Class 1 Module

The LM072 Bluetooth Class 1 Module comes with SPP Stack but can also work with a range of Bluetooth profiles such as SPP,HSP/HFP,HID,DUN and supports USB, UART & PCM interfaces. It supports 3.0v to 3.6v input and has a footprint of 28.2mm x 15.0mm x 2.8mm.The Bluetooth Class 1 Module is designed to provide excellent performance with minimum power consumption and is targeted to offer competitive edge to the products it is used with.

LM072 Bluetooth Class 1 Module Applications

The LM072 Bluetooth Class 1 Module is also used within our LM300 Bluetooth Com Port Ethernet switch, which uses LM’s multipoint stack, this firmware allows for up to 3 simultaneous connections, which pass data at the same time dividing the bandwidth between the connections, yet not seeing any drop off in bandwidth from any single connection within the division when used with a serial bus.LM offers a free Design In service that allows us to show your team several antenna design options as well as integration to enable the LM072 firmware commands to work with your own products.
