3.2.6. Using the IoT module without the breakout board

The IoT module can be used without connecting it to the board-to-board connector if external power is
supplied. In this way the XM122 can operate as a standalone module or connected to other hardware.
In XM122 R2D a NOT MOUNTED battery connector has been added to the design. For XM122 R2C,
power supply leads or connection to a battery can be soldered onto the pads of C38 (not mounted), see
