Description

Beacon Mini-TX a mini version of regular Super-Beacon

  • Has 6D IMU onboard: 3D accelerometer + 3D gyroscope
 
Mini-TX is great to track micro-drones.

However, if you need to connect with PixHawk, for example, then Super-Beacon is easier and recommended, because it has 4×4 pins for a 2-wire connectivity with PixHawk.

Comparison to Super-Beacons and Beacon HW v4.9:

  • Mini-TX is a TX-only beacon – it can transmit ultrasonic, but can’t receive it. Super-Beacons and Beacons HW v4.9 are dual-use beacons – they can receive and transmit ultrasound
  • Mini-TX Smaller size and lighter: 47x42x15mm & 25g vs. 55x55x33mm & 62g (or 55x55x64mm with antenna). Size is the key advantage of Mini-TX. Without battery and housing – bare board with transducers – it weighs just 6.4 grams
  • Battery – 250mAh vs. 1000mAh in Super-Beacons and Beacons HW v4.9. But Mini-TX 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-TX has only USB (virtual UART) output – no additional pins. Super-Beacons have 4×4 for easy interfacing with PixHawk or other devices
  • Mini-TX like Super-Beacons have 6D IMU
  • Embedded antenna in Mini-TX – smaller size, but smaller radio coverage ~50m
  • Range in ultrasonic is weaker than that of Super-Beacons, but still reaches 30m. The range more depends on the ultrasound frequency than on the difference Mini-TX vs. Super-Beacon
  • Mini-TX has only 31kHz frequency
  • Mini-TX 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.
