The GrowSpace Creator Expansion Kit Q1 is an expandable development package designed for easily building UWB-based high-precision indoor positioning systems. It is optimized for researchers, developers, PoC (Proof of Concept), and field testing in industrial environments.
The kit includes 4 UWB Anchors Q1, 1 Gateway Q1 for data collection, and 1 Developer Tag Q1, Z Bracket 4EA allowing you to set up an indoor location-based testing environment right out of the box.
By using UWB technology with the TWR (Two-Way Ranging) method, it enables real-time positioning with an error margin of less than 10 cm, and can be used in various scenarios such as smart factories, logistics robots, and autonomous driving simulations.
It is applicable to a wide range of fields including smart factories, robot navigation, worker safety management, and logistics automation research.

The UWB Creator Expansion Kit is a complete RTLS system designed for ultra-wideband (UWB) indoor positioning. It is built for use in various research, development, and testing environments where real-time precision tracking is essential. Based on the TWR (Time-of-Flight) protocol, the system offers sub-10 cm accuracy and high-performance data transmission.
The kit includes 4 UWB anchors, 1 gateway, 1 developer tag and Z Bracket 4EA. It supports location data transmission over the network via MQTT and REST API. It can be integrated with server- or cloud-based control software (SpaceCloud, SpaceCloud Pro) for real-time location monitoring, danger zone configuration, and event log analysis.
Thanks to its gateway-based architecture, the system can manage larger spaces and more tags reliably. It also supports flexible server integration for experimental setups using Python, Node.js, or MQTT brokers.
• Provides 10–20x higher accuracy compared to BLE through TWR-based distance measurement
• Suitable for industrial environments and large-scale facilities
• Up to 10 updates per second
• Gateway-based parallel processing improves multi-tag tracking performance
• Supports up to 30 tags with anchors placed at 30m intervals
• Enables real-time server integration and cloud uplink via gateway
• Compatible with various devices such as Raspberry Pi, Arduino, and computers
• Can be used alongside other IoT technologies like BLE, Wi-Fi, and LoRa
• Additional tags and anchors can be added as needed from the base kit configuration
• Scalable for larger areas and complex environments with extra UWB tags and anchors
This is a fixed UWB (Ultra-Wideband) positioning device that measures the distance to tags in indoor spaces and provides key data for calculating real-time positions.
This is a wired and wireless network gateway device that collects position data from tags and anchors and sends it to a server (local or cloud) via the MQTT protocol.
It supports both Wi-Fi and LAN connections, making it essential for large-scale spaces and remote monitoring systems.
This is a mobile UWB tag used in ultra-precise UWB positioning systems.
It calculates its real-time location using the TWR (Two-Way Ranging) method and is designed for use across a wide range of applications.
The software allows you to configure detailed settings for anchors, tags, and listeners, and supports real-time monitoring of tag movements.
The Bracket is a dedicated mounting bracket designed to securely fix the Anchor in various installation environments. It supports flexible installation on walls, ceilings, and partitions, while ensuring a clearance distance of 10 cm (100 mm) to provide an optimal environment for UWB signal transmission and reception.

The bracket is an essential accessory designed to install the anchor 10cm away from the wall, minimizing UWB signal reflection and interference and ensuring precise positioning accuracy.
If the anchor is mounted directly on the wall, signals may be reflected or absorbed, which can significantly reduce positioning accuracy.
For stable and reliable positioning, using the bracket is mandatory.
GrowSpace delivers 10–30 cm accuracy with a maximum range of 25 m (line-of-sight), both indoors and outdoors. Recommended anchor spacing differs by environment:
| Environment | Accuracy | Max range (LoS) | Anchor spacing |
|---|---|---|---|
| Indoor | 10–30 cm | 25 m | up to 15 m |
| Outdoor | 10–30 cm | 25 m | up to 20 m |
Indoor walls and structures reflect UWB signals, so closer spacing is recommended; open outdoor areas allow wider spacing.
You need at least 3 anchors for 2D real-time location tracking (trilateration of X and Y).
Adding more anchors improves both accuracy and stability.
Yes. Positioning continues as long as 3 or more anchors stay active, since the system needs at least three working anchors to calculate location. Depending on which anchor fails, accuracy or coverage in some areas may be affected — so for critical spaces we recommend installing 1–2 extra anchors as backup.
Battery life depends on the tag type:
| Tag type | Use | Battery life |
|---|---|---|
| Wearable tag | Tracking people | up to 7 days |
| Asset tag | Tracking objects / logistics | up to 70 days (low-power mode) |
Actual runtime varies with the update rate (e.g. 1 Hz vs 10 Hz), movement frequency, and transmission interval.
The Creator Kit Q1 includes a Listener, built for local RTLS testing. Here’s how the two compare:
| Item | Gateway (in Expansion Kit) | Listener |
|---|---|---|
| Connection | Wi-Fi / LAN | USB (direct) |
| Use | Real-time operation | Testing |
| Target | Cloud, Server | PC, MCU |
When you move from testing to a deployed service, you can add a Gateway.
Avoid installing anchors near metal or glass surfaces — UWB signals reflect or bend on these materials, causing multipath interference that reduces accuracy.
Yes. GrowSpace uses MQTT, so it integrates with Python, Node.js, Java, and other environments.
Location data updates at up to 10 times per second (10 Hz), and the gateway handles up to 150 messages per second.
| Update rate | Tags tracked simultaneously |
|---|---|
| 10 Hz | up to 15 tags |
| 1 Hz | up to 150 tags |
Fast and reliable even when tracking many tags at once.
