4.7 GPIO
The J20 connector provides access to the GPIO port. GPIO is generated by the Nuvoton NCT5104.D I/O
controller. GPIO pins operate at 3.3V logic level. The pinout for GPIO is listed in Table 9

4.8 RTC battery
A 1.5V LR44 battery is used real-time clock and NV-CMOS parameter retention.
4.9 Temperature Monitoring
CPU core and motherboard temperature is monitored by a thermal sensors. To install driver support for
temperature sensor, please install the
lm-sensors
package. Under Debian 9, use the following command:
# Install software
> sudo apt-get install lm-sensors
# Execute software
> sensors

4.10 Wi-Fi
Netrunr Edge uses a Realtek RTL8811CU Wi-Fi radio. This is a dual-band 802.11ac (abgn+ac) Wave2, MU-
MIMO chipset. Since this radio was recently released, the drivers may not be present in all Linux
distributions.
