BeagleBone TiWi-5E Cape w/ External Antenna

The BeagleBone TiWi-5E Cape w/ External Antenna is an add-on board that provides Wi-Fi capability for the BeagleBone. This cape is equipped with LSR TiWi-5E module that is capable of providing high performance 2.4 GHz and 5 GHz IEEE 802.11 a/b/g/n. The TiWi-5E chip use on this cape is based on the Texas Instrument WL1273L chipset. This cape uses an external antenna.

Note: Bluetooth for this cape is NOT supported in the latest Angstrom release for BeagleBone.

Note: Hardware incompatible and will damage BeagleBone Black if used together.

Getting Started

Required Setup:

  • A BeagleBone TiWi-5E Cape w/ External Antenna
  • A BeagleBone (with supported software)
  • A 5V DC power supply (we recommend 5V - 2A)
  • A mini-USB cable

Following the instructions below to start using your BeagleBone TiWi-5E Cape w/ External Antenna:

  1. Mount the BeagleBone TiWi Cape to the BeagleBone
  2. Make sure the SD card using with BeagleBone has supported Angstrom image or later
  3. Plug in a 5V DC power supply to the DC connector on BeagleBone
    • Note: We recommend using a 5V - 2A supply. However, more current supply may be required if more capes or peripheral devices are connected.
  4. Connect the BeagleBone to your PC using mini-USB cable
    • Note: the mini-USB port on the cable should go to the mini-USB connector on the BeagleBone. The other end of the cable should go to PC
  5. Open a terminal program (e.g. TeraTerm) and connect to the corresponding COM port for BeagleBone
  6. Log in as root
  7. Now you can start using linux command for wireless device.
  8. Example: use following command to scan available networks
    • iw dev wlan0 scan
    • For more information please visit Wireless Kernel
    • Note: Latest Angstrom image for BeagleBone supports iw and nl80211
