3.1 Schematics

Figure 4-1 shows the schematic of the A1 sub board on the TMCS1127AEVM PCB. Only the schematic for the A1 (25mV/A) sensitivity variant is demonstrated in this document, as all variants use the same circuit and same PCB layout. Only U1 changes from board to board. All components associated with the 25mV/A sensitivity variants have the nomenclature "_1" appended at the end. The 50mV/A sensitivity variants have "_2" appended, the 75mV/A sensitivity variants have "_3" appended, the 100mV/A sensitivity variants have "_4" appended, and the 150mV/A sensitivity variants have "_5" appended.
