The coupon boards are designed to test the complete TMAG5124 family, including in-axis and TO-92 packaged variants.

U1-U4 are TMAG5124E1CQDBZ, TMAG5124F1CQDBZ, TMAG5124G1CQDBZ, and TMAG5124H1CQDBZ versions of the TMAG5124 respectively. These devices allow the user to test all sensitivities of the TMAG5124 (3mT, 6mT, 10mT, and 15mT), with an active low current of 6 mA when a magnet is present at the device. The in-board measurement slot is for a future "in-plane" version of the device.

U5-U8 are for a future option of the device in TO-92 package.

C1-C8 serve as bypass capacitors for the various devices and help to mitigate noise on the power supply supplied to the device.
