Power pin header (J3)
The power pin header J3 provides the possibility to supply the XM132 board with power from an
external power supply. In Table 3, the pin assignment of J3 is shown:

2x5 JTAG/SWD pin header (J6)
The 2x5 JTAG/SWD pin header (1.27mm pitch) contains the signals needed for flashing the XM132
MCU via the SWD interface. The pinout matches that of the Cortex 10-pin JTAG/SWD Connector
and is found in Table 4.
