This section describes the main TMAG5x73 devices and supporting components. The component footprints that are duplicated on both the A1 and A2 parts of the board have an _A1 or _A2 appended to the end of the component names to indicate whether the component is on the A1 or A2 part of the board. With the exception of components U1_A1 and U1_A2, which correspond to different TMAG5x73 device variants, all other _A1 components use the same components as the corresponding _A2 components.

The EVM has the following components:

• U1_A1 is the TMAG5x731A1 device on the A1 part of the board and U1_A2 is the TMAG5x73A2 device on the A2 part of the board.
• C1_A1, C1_A2, C2_A1, and C2_A2 are bypass capacitors that are placed near the sensor to help mitigate power-supply noise and provide current quickly to the device when needed.
• J1A_A1 and J1B_A1 are the main header pins that connect the digital and power pins of the TMAG5x73A1 to the SCB Controller. Similarly, J1A_A2 and J1B_A2 are the main header pins that connect the digital and power pins of the TMAG5x73A2 to the SCB controller.
• Resistors R1_A1 and R1_A2 connect the 3.3V rail from the SCB board to the TMAG5x73A1 and TMAG5x73A2. Remove these resistors if the user wants to power the TMAG5273 from a different power source.
• Resistors R2_A1 and R2_A2 are the pullup resistors on the SCL pin of the TMAG5x73 devices. Similarly, resistors R3_A1 and R3_A2 are the pullup resistors on the SDA pin of the TMAG5x73 devices. R4_A1 and R4_A2 are the pullup resistors on the interrupt pin of the TMAG5x73 devices.
