3.1.1 Hardware

The TIDA-010197 hardware includes two variations: an external ADC version utilizing the ADC128S102-SP, and an internal ADC version using the internal ADC of the MSP430. Both variations include the same power tree, sequencing, outputs and measures the same parameters (voltage, current, and temperature).

To power up the board, an external 12-V and 5-V power supply is required and is connected via J15 for the external ADC version and J35 for the MSP430 version.
