Excellent precision for indoor projects
I used this board for a warehouse tracking prototype and the 10cm accuracy is impressive. Setup with the ESP32 environment was straightforward.

Great hardware, documentation could be better
The module works as advertised regarding ranging capabilities. However, finding detailed pinout diagrams required some digging in community forums.

Reliable for industrial prototyping
Bought a batch for our makerspace. Users find it easy to program and the build quality feels solid for repeated use in workshops.

Works well but range is limited
Precision is high, but remember this is strictly short-range. Do not expect it to work through thick concrete walls, but that is expected for UWB.

Good value for learning UWB
As a student project, this board provided a great introduction to UWB technology without breaking the bank. Ranging is consistent within line of sight.

Perfect for robotics navigation
We integrated four of these nodes for our robot localization system. The latency is low and the data is stable even with minor obstacles.
Q: Can this be powered via USB?
A: The board features a USB interface for programming and can be powered via the USB port, though external 3.3V-5V supply is recommended for stable operation during heavy transmission.
Q: Does this board come with antennas included?
A: Yes, the NodeMCU-BU01 comes with onboard PCB antennas suitable for UWB frequencies.
Q: What is the maximum number of nodes supported in a single network?
A: Theoretically, you can support many nodes, but practical performance depends on your specific firmware implementation and airtime management. Most users successfully manage 10-20 nodes.
Q: Is this compatible with Arduino IDE?
A: Yes, since it is based on an ESP32-compatible architecture, you can program it using the Arduino IDE with the appropriate board manager packages.
Q: Does it support Two-Way Ranging (TWR)?
A: Yes, the hardware supports Two-Way Ranging protocols, which are essential for achieving the high-precision distance measurements advertised.
