MSP430 i240 EVM Features and Setup

Bart Basil introduces the new server power monitor EVM featuring the MSP430 i240 microcontroller. The EVM is designed for embedded metering applications, measuring energy, voltage, current, frequency, and power. It includes essential hardware for evaluation, such as a debug header, power supply, and communication interface. The firmware offers features like automatic AC/DC input measurement and no separate calibration. A demo shows the EVM's ease of use, setup, and real-time monitoring capabilities. Calibration and performance are discussed, highlighting error factors and improvement suggestions. Additional resources are available for further exploration.
