This option allows the LM53X to be mounted directly on and powered by an Arduino Uno board. Powered from Arduino board (power switch positioned to the right in RED) Note: No jumpers should be connected to CN3, CN4 and CN7.ģ. This option is useful when the developer wants to test their software in a “real world” powered situation. The battery connector is situated underneath the board and accepts a CR2032 Coin Cell Battery. Battery Power (power switch positioned to the left in RED) Requiring a USB to mini USB cable to connect the programmer board to the development PC.Ģ. USB powered from the CSR USB-SPI Programmer Board (power switch positioned to the right in RED).
*Note: for connection (option 2) the pins need to be angled slightly inwards and ideally some soft foam can be placed under the Module (to ensure some upward force is applied to the module and a good connection is made between the module and the pins). Connected via 1.27 mm pitch pins that is soldered to CN1 (for a temporary connection).*.Soldered to the Pads on CN1 (for a permanent connection).The LM930/ LM931 module is mounted in one of 2 ways to the LM53X: LM53X Hardware Mounting the LM930/ LM931 to the LM53X LM53X (including the CSR USB-SPI Programmer Board).CSR toolchain (including CSR ♞nergy SDK (xIDE)).LM offer project support including developing new application firmware to meet your project requirements. A good starting point to developing your own user application firmware within the provided CSR ♞nergy SDK. This user guide explains how to use the LM930/ LM931 Bluetooth Smart Module on the LM53X development kit.
