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.

Like the sunscree - not the spray can
Style: SPF 50, Size: 6 Fl Oz (Pack of 2)
Sunscreen itself did a great job with our snorkeling and scuba diving. Long lasting and didn't rub off in spots where masks and other things can leave spots unprotected. However, the spray can itself was difficult. Even when being sure it was completely in the unlocked position, it would take me two thumbs at full pressure to get it started spraying at times. Definitely, only a couple of us in the party were the appliers as we could get it started.

Love it! Eco-friendly and Easy-to-Use Spray
Style: SPF 50, Size: 6 Fl Oz (Pack of 2), Style: SPF 50, Size: 6 Fl Oz (Pack of 2)
I really like the Alba Botanicals Coconut Clear Spray! Not only does it give me a refreshing coconutty vibe, but it’s also biodegradable and cruelty-free, which is important to me. 🐰♻️ The spray-on application is a breeze, and I love how it doesn’t leave that annoying greasy feeling on my skin. It absorbs quickly and leaves my skin feeling soft and nourished. Perfect for those sunny beach days or any time I need a quick spritz of hydration. I highly recommend this coconut clear spray to everyone who values eco-friendly choices and easy-to-use skincare products.

Great product, bad packaging
Style: SPF 50, Size: 6 Fl Oz (Pack of 2)
I love this sunscreen! I use it on myself and my child and it works very well. However, the spray nozzle on one of the cans is locked and it will not work. I have tried to turn the lock, lift it up, etc., to no avail. This item is also not returnable. $20 for 1 can of sunscreen is quite expensive.

Great product
Style: SPF 50, Size: 6 Fl Oz (Pack of 2)
Product is great with good coverage and ease of use. Much better than comparable products because it is very light feeling and doesn't leave a heavy or sticky residue on your skin. Perfect protection for anyone who burns easily or fair skinned. However I paid for the extra rushed 3 day shipping and it was delayed and I wasn't reimbursed the extra shipping charges even though it arrived 6 days later.

Save your money- don’t buy
Style: SPF 50, Size: 6 Fl Oz (Pack of 2)
Purchased this for our trip to Mexico. At two cruise ports we were doing a combination snorkel and pool day. I got this sunscreen because it was reef friendly and came with two bottles. Both bottles were IMPOSSIBLE to spray. You could not sunscreen yourself because you had to hold the bottle just right, push down with extreme force, and have your fingers place very specifically on the lid. My 13 year old and husband couldn’t even use the bottles. I did figure it out so I had to continually sunscreen everyone in the family. No one in my family has sensitive skin, but we all ended up with a fine rash after using this sunscreen. On days prior we used another brand and no one had a problem. We also reapplied often (every 60-90 min) and we still got pretty burnt. Maybe we got a bad batch…
