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.

would this work if you upsize it to say 50x? Would it work on a drone so big you could sit it in and fly down the highway? Could it control the x & Y axis movement over a 100 miles distance?. Thanks, Roger Mc

We are focusing on indoor positioning and GPS denied areas. Thus, for outdoor, you better use RTK GPS.

Yes, it is possible to control X,Y,Z, but, again, within the size of the map, which is usually up to 100-200m indoor. The map would consist of multiple submaps each – up to 30m size.
