Marvelmind HW4.9 Indoor Positioning Beacon

Want an indoor GPS that actually works? The Marvelmind HW4.9 indoor positioning beacon is your ticket to high-precision tracking without relying on spotty satellite signals. Whether you're building a fully autonomous robot tracking system or just trying to locate where your cat hides the 10mm socket, this Marvelmind beacon delivers sub-2cm accuracy. It uses ultrasonic pings and ISM band telemetry, safely dodging CAA paperwork purgatory since it’s strictly an indoor positioning system. And yes, unlike a Raspberry Pi during the supply chain dark ages, this hardware is actually in stock.

Why You Want It

You've spent 40 hours coding an autonomous rover, only for it to aggressively repeatedly ram the skirting board because its odometry drifted. Sound familiar? By adding this HW4.9 beacon to your Marvelmind indoor positioning network, you get absolute, ground-truth coordinates. It features a built-in IMU for that sweet extra motion data, and you can switch it between mobile (on your robot) or stationary (on your wall) via software. We know, we're shamelessly trying to up-sell you to increase your coverage area, but hey, servers aren't free and Joshua Bardwell won’t fund our yacht.

Specifications

  • Accuracy: ±2cm (because 3cm is just embarrassing)
  • Frequencies: 915Mhz 
  • Battery Life: Up to 1300 hours active (so you'll lose the charger long before it dies)
  • Interfaces: USB, UART, SPI, I2C (wire it backward to release the magic smoke)
  • Range: Up to 50 meters (plenty of room to fly indoors without turtle mode)
  • Sensor: Built-in IMU (for when you need to know exactly how violently you crashed)

What’s in the Box*

  • 1× Marvelmind HW4.9 Beacon
  • (Probably zero hand-holding, welcome to the maker hobby)

Disclaimer

Manufacturer packaging and accessories may randomly change without warning, but we guarantee you'll receive the genuine HW4.9 beacon you paid for.

Color is not the same as picture, too light, assembly is harder than it should be
Size: g:Square Table with Umbrella Hole, Color: Light Grey
I had higher hopes for this table given the 80 dollar price tag. The gray finish is MUCH brighter than what is displayed in the picture. What's advertised matched the gray Adirondack set that I currently have in my yard, what came in was about 5 shades lighter. The assembly only had a few steps to it with a total of 8 bolts but it was more difficult that it had to be has the holes didn't line up very well and I actually had to bend one of the metal pieces to get the screw to line up. I ordered this piece initially to serve two purposes, the first was to add more stability to my ever blowing over umbrella, the second was to add a matching table piece in-between my two Adirondack chairs. This piece does neither very well. It is too light in color to match and serve to complete the set, and it is not heavy enough to add any layer of stability. For these reasons, I cannot recommend this piece.

Nice, but...
Size: g:Square Table with Umbrella Hole, Color: Black
Second one I bought. So I do like it, but for the price they could include an extra screw and washer. Also it would be much more convenient if the holes would line up correctly. That's why I gave only 3 stars. But it is a nice table.

Durability
I was very satisfied with the quality of another Best Choice Products: Ice Chest. So, I was happy to see the umbrella stand, weighted by water, was available by this company. It is, once again, made very resilient and strong to withstand tipping over. I'm a happy customer of this company's products!
