ROCKY100+MCU development board is a passive device development platform. The development board includes a ROCKY100 chip and an MSP430FR2433 microcontroller. The pins of the microcontroller are fully extended, making it convenient for users to connect their own circuits and evaluate their projects. The ROCKY100 chip, in conjunction with the existing antenna on the PCB board, absorbs the energy emitted by the reader/writer, converts it into voltage, and supplies power to its own, microcontroller, and external connection circuits of the user.
