Page 9: Xb122 Breakout Board
3.1. XB122 Breakout Board 3.1.1. Overview The XB122 is a breakout-board designed for the XM122 IoT Module. It makes the interfaces from the XM122 module accessible for evaluation and debug. It also enables flashing of the XM122 via USB- UART or SW-DP. The XM122 is connected to the XB122 via a board-to-board connector on the top side of the PCB. -
Page 10: Power
When the LED D1 on the XB122 is lit, the USB-UART chip is powered and ready to use. If SW1 is set to “VBUS” it also means that XM122 is powered and ready to use (if connected to the board-to- board connector on the top side of XB122). -

Page 16: Connectors
3.1.6. Connectors USB (J1) USB is used as power supply for the XB122 and the XM122 as well as for flashing and communicating over UART. USB is connected to the FTDI chip FT230XS which converts the UART interface from XM122 into USB data signals. The pinout of J1 is shown in Table 2. - Page 17 UART_RTS 2x5 JTAG/SWD pin header (J4) The 2x5 JTAG/SWD pin header (1.27mm pitch) contains the signals needed for flashing the XM122 MCU via the SWD interface. The pinout matches that of the Cortex 10-pin JTAG/SWD Connector and is found in Table 4.
- Page 18 There are two buttons on the XB122. SW2 controls the signal “DFU” (Device Firmware Upgrade) connected to XM122 and SW3 controls “NRST” connected to the XM122. In Table 7 the state of the buttons and the corresponding signal states are listed.

Page 28: 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 Error! Reference source not found.. -
