The Arduino microcontroller is connected to the LM930/ LM931 via the LM53X. The 4 edge connectors (Marked with yellow rectangles) needs to be mounted as if the LM53X is an Arduino “Shield” with the pins protruding from the bottom of the PCB.Ĭonnecting External Devices Connecting an Arduino Board 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.
This user guide explains how to use the LM930/ LM931 Bluetooth Smart Module on the LM53X development kit.
