In summary, the i20xx is a programmable MCU that designers can program with ones own metrology software. The MSP-TS430RHB32A is a standalone socket based target board used to program and debug the MSP430. Also available are the MSP430-i2040 and MSP430-i2040SUBMTR EVMs which are complete metrology systems. To complete the whole ecosystem, Texas Instruments also provides the Energy Library software suite for development. The library provides easy-to-use code for developers who need to perform standard tasks without needing to know all details behind each peripheral of the MCU.
