Overview
LM073 is LM Technologies Ltd Class 1 Bluetooth Data module with onboard antenna. This module is a CSR Bluecore 4 (BC04) chip
based surface mount module available with Bluetooth Serial Port Profile (SPP) firmware.
The module acts as a standalone unit (i.e. it does not need a host to drive it) and can interface with embedded microcontrollers via
UART.
It operates over a voltage range of 3.0V to 3.6V and gives excellent performance over a distance of 70-100m with onboard antenna.
This module is available with Bluetooth 2.0+EDR as well as Bluetooth 2.1+EDR compliant SPP firmware.
