C1-Public
The NORA-W106 module can check if the CS0 signal is low. If it is low, then there is no card at the
MicroSD card slot and can set an interrupt to the pin to be notified for a card insertion event. If the
CS0 signal is high, then the card is inserted, and can proceed to initialize the SPI peripheral.
Table 4 describes the pins used on the MicroSD card slot.

2.1.7 Qwiic
XPLR-HPG-1 board has a standard Qwiic connector (J22) for connecting external I2C devices of the
Qwiic ecosystem. The interface includes two 2.2 k
Ω pull-up resistors referenced to 3.3 V on the SDA
and SCL signals. The signals are shown on each mikroBUS slot.

2.1.8 Buttons
XPLR-HPG-1 supports three buttons (RESET, BTN1, and BTN2). The schematic circuit of these
buttons is shown in
Figure 15 . The buttons are accessible from the front side of the PCB.
