Description

Beacon Mini-TX a mini version of regular Beacon HW v4.9 with IMU

  • Has 6D IMU onboard: 3D accelerometer + 3D gyroscope

Comparison to Beacon HW v4.9:

  • TX-only beacon – can transmit ultrasonic, but can’t receive it. Beacon HW v4.9 is dual-use: can receive and transmit ultrasonic
  • Mini-TX Smaller size and lighter: 47x42x15mm & 25g vs. 55x55x33mm & 62g (or 55x55x64mm with antenna). More on comparison
  • Battery – 250mAh vs. 1000mAh in a regular beacon. But Mini-beacon has a new more efficient ultrasonic TX module, thus, battery lifetime in TX mode is even superior to the Beacon HW v4.9
  • Tested battery lifetime with 8Hz – 96h. With lower update rate – nearly proportionally longer. Very efficient ultrasonic TX module
  • Mini-beacon has only USB (virtual UART) output – no additional pins
  • Mini-beacons always have embedded IMU – newer and better, but it has 3D accelerometer and 3D gyroscope, but no magnetometer (which we do not recommend to use indoor anyway, due to magnetic field distortion indoor)
  • Embedded antenna – smaller size, but smaller radio coverage ~50m with regular Modem HW v4.9 as compared with ~100m of Beacon HW v4.9 with Modem HW v4.9
  • Range in ultrasonic is virtually on par with regular Beacon HW v4.9 – up to 30m with Beacon HW v4.9 as RX beacon. At the same time, for example, a combination of Mini-RX beacon + Mini-TX provide a better coverage and a stronger signal, than Beacon HW v4.9 + Beacon HW v4.9
  • This HW supports license-free 915MHz ISM band (US) and license-free SRD band 868MHz (EU), i.e. 433MHz (EU band) is not supported and not planned

Hi, I have purchased this module and need to have its 3D model to add to my design. Would you please send me a link to get it ? Thanks.

Is it possible to output the location of the beacon to Pixhawk using the micro-USB port on the Mini-TX?

Yes, it is possible. But an external converter board must be used, for example: https://www.hobbytronics.co.uk/usb-host-serial or similar.

Mini-TX and Mini-RX are small and don’t have dedicated UART or SPI pins. Super-Beacons and Beacons HW v4.9 or Modem HW v4.9 or Super-Modem or Industrial Beacons have them.
