USB Ports:
Cape has two USB Connectors for the user to access.
● P7 (MINI USB Device Port Connector) is to connect the cape to the Beaglebone CPU
USB host port P3.
● P8 (Alternate USB-A Port Connector) is a Hi-Speed USB Port, Max 500 mA, Type-A.
For the USB ports enumeration of the module, please refer to the VAYU2 Wiki Page.
RS232 Ports:
2x RS232 serial ports.
● Pluggable 2 mm 3-pin Terminal Header
● ±25V tolerant I/O
● ESD Protection Level Upto ±15 kV HBM
● Operates up to 250 kbps

Jumper Settings:
The user can select the RS232 Communication ports Serial Port-1 or Serial Port-2 by using the
Jumper J7. Serial Port 1 is the UART1 of the Beaglebone CPU and Serial Port 2 is the UART2 of the
Beaglebone CPU.
Setting up the system:
1. Place a micro-SIM in the SIM card slot and connect the respective antennas to the SMA
connectors.
(P2&P3 are SMA connectors for connecting GSM antennas, P4 is for the GNSS antenna).
2. Mount the VAYU2 cape on Beaglebone Black.
3. Ensure the power jumper J1 with other jumpers according to your application.
4. Connect the USB-A to mini-B USB cable provided with the cape between Host port on
Beaglebone Black and mini USB device port P7 on Cape.
5. Now power up the full setup using a 5V DC adapter (min 2.5A) to the BeagleBone system’s
barrel jack. The D2 LED on the cape will glow along with LEDs on the Beaglebone black.
Note: Before powering up ensure correct software image is loaded in Beaglebone black or VIBE/VIBE2
Before proceeding further ensure the D2 LED is glowing properly. Make sure that the
adapter being used is of proper rating and has been connected properly.
When using the GNSS Section, ensure the GPS Antenna is faced to Open Sky for better
accuracy.

Do not try to power up using a USB cable alone. Always power up the system with a
DC adapter. Also while disconnecting power, the USB cable should be removed
before the DC adapter.
Before powering down the system, always ensure to Turn OFF the Modem using the
PWRKEY turn ON/OFF control pin or using the AT Command AT+QPOWD.
