I have not physically tested this device yet, but typically UWB modules can have a range of up to 100 meters or around 300 feet, which is more than enough for many applications. Also, UWB frequenceis can work through walls, but it may be less accurate or cause desyncing with the drone.

Note: These anchors do not actively run the computations to position the drones, you must also have a dedicated ground station with wifi such as a Raspbbery PI Zero 2 W for computing.

The KiCad project lives in the DerpyDoggo11/LSwarm-Anchor repository on GitHub; these links point at the commit this page was built from.

LSwarm-Anchor: common questions

What microcontroller does the LSwarm-Anchor use?

The LSwarm-Anchor is built around the ESP32-C3-MINI-1U-N4, from the ESP32 family.

How big is the LSwarm-Anchor PCB?

The LSwarm-Anchor measures 94.5 × 31 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the LSwarm-Anchor?

52 components, from 28 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the LSwarm-Anchor design files?

From the DerpyDoggo11/LSwarm-Anchor repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the LSwarm-Anchor design in my own project?

The repository has no license, so all rights stay with DerpyDoggo11. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the LSwarm-Anchor without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
