Page 4: Operation
Measurements The DRV5055EVM measures a magnetic field with multiple devices and the respective gain variants. Push-button S1 selects the different gain variants of the DRV5055 devices. The devices are arranged such that gain variants increase sequentially from right to left. The LCD displays the measurement corresponding to the selected device. -
Page 5: Hardware
DRV5055 family of devices. Theory of Operation The DRV5055EVM is a plug and play board, requiring only that the user supply power and provide a magnetic stimulus after the initial calibration. The ease of operation can be attributed to the onboard microcontroller. - Page 6 Hardware www.ti.com Circuitry This section summarizes the DRV5055EVM components. 3.3.1 C1, J1, R1, and R2 J1 serves as the connector for an external MSP-FET Flash Emulation Tool to connect to the board. C1, R1, and R2 are the additional passives required for the emulation tool to effectively communicate with the MSP430FR4133 for the purposes of programming and debugging.
