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.
