4.1 Step 1: Hardware Preparation

Hardware board:

If users want to evaluate this implementation, then do the hardware setup first. If users only want to evaluate the gauge software, then only a LaunchPad™ is needed and input the prepared voltage and temperature data into the MSPM0 gauge algorithm.

Test setup:

To do the test and evaluate MSPM0 Gauge performance, users need to prepare a source meter or other battery test machines to control the battery charge and discharge. This is also helpful if users have a thermo stream to evaluate the gauge performance under a different temperature.
