ARCA-V2 systems combine wireless communication (cellular WAN, WiFi/BLE LAN) with a power CPU system (TI BeagleBone compatible) and several wired interfaces such as Ethernet, USB, I2C. It is a multi-function system which can be used as:
- LAN to WAN Router gateway
- Data aggregator from a local network of devices
- Sensor to Cloud Gateway
- Remote access control system for industrial equipment

WiFi & BLE
ARCA-V2 has Realtek RTL8723BU chipset for WiFi+BLE.
RTL8723BU is an 802.11bgn 2.4G single-chip that integrates Wireless LAN (WLAN) and a network USB interface (USB 2.0) controller with integrated Bluetooth 2.1/3.0/4.0 controller.
In ARCA-V2 pre-compiled Yantrr Boot Image the WiFI interface wlan0 is configured in Master Mode i.e. AP/Hotspot mode. The default SSID of ARCA's WiFi hot-spot is its Board Serial Number and the password is yantrrI0T.

GPS
A particular ARCA-V2 Model can have either embedded GPS or standalone GPS support.
The Embedded GPS is enabled through the Modem module with which the ARCA-V2 is assembled. Since the embedded GPS is handled through Modem, the NMEA-0183 messages are accessed using particular AT command with respect to Modem.
The standalone GPS module is interfaced over UART4 of ARCA-V2. NMEA-0183 messages from this can be accessed over /dev/ttyO4 port at baud rate of 19200.
USB Ports
ARCA-V2 have Three USB 2.0 HS host ports with type A socket. Each USB port has current rating of 500mA max.
LAN Port
ARCA-V2 has one dedicated Ethernet Port : 10/100Mbps, RJ45. Using this the ARCA-V2 can connect to the Local Network Router or can share the Cellular Data connection to other Local Devices through direct Ethernet connection or via network switches.
