One single module can not work independently and can not achieve any useful function. A minimum high-precision positioning system（3 anchors and 1 tag） can be achieved by 4 ULM3(ULM3-PA/ULA1) modules.
A typical high-precision positioning system（4 anchors and 1 tag） can be achieved by 5 ULM3(ULM3-PA/ULA1) modules.The UWB Ultra Wideband Positioning Module STM32 + DWM3000
(ULM3) is based on the latest DWM3000 series chip.
The core UWB module of ULM3 is an official Decawave DWM3000, and the MCU is STM32F103CBT6 (or GD32F103CBT6).
ULM3 can be used for precise ranging, indoor positioning, and other high-speed data communication applications. It also integrates an OLED display, making it easy to use with its small size and high precision.
For positioning applications, ULM3 can be used as an anchor or tag, and multiple ULM3 modules can form a complete TWR positioning system (RTLS1). It should be noted that a minimum high precision positioning system with 3 anchors and 1 tag can be achieved by 4 ULM3 modules, while a typical high precision positioning system with 4 anchors and 1 tag can be achieved by 5 ULM3 modules.

The following products are not eligible for return or refund under this policy:
Used, damaged, or modified products — Items that show signs of use, wear, or alteration, making them unsuitable for resale.
Consumables — Use and wear-and-tear components, altered or depleted through use (e.g., batteries, belts, brushes, gears, filament, tires, disposable bags, lubricants, greases, waxes, etc.). Not eligible for return once opened or used.
Perishables — Goods liable to deteriorate or expire rapidly. Not eligible for return.
Sealed goods (health or hygiene) — Items sealed for health-protection or hygiene reasons (e.g., masks, gloves, odor-absorbing products). Not eligible for return once unsealed.
Build-it-yourself products and items requiring customer assembly — Including robots & kits, robot parts, and other products requiring assembly or soldering. Not eligible for return once assembled, soldered, or installed.
Digital Goods, Software, and Apps — Final sale only, due to licensing restrictions.
Clearance Items — Products identified as clearance or final sale, including end-of-life or discontinued items.
Custom-made, personalized, or special-order items — Products manufactured, configured, adapted, or built to the customer's own specifications and requirements.
On-Demand Items — Standard catalogue products not stocked by RobotShop and ordered specifically to fulfill a customer request.
While the same return policy applies, these orders require a separate contact process for returns.
RobotShop Fulfilled Orders → submit a support ticket from your account under My Support Tickets.
Marketplace Vendor Orders → submit a ticket from your account under My Marketplace Tickets to contact the vendor directly.
Note: Marketplace vendor products are normally labelled with SKUs starting with RM, and identified on the product page with the mention "Sold and fulfilled by [Vendor Name]".
