UWB Module ESP IDF: common questions
What microcontroller does the UWB Module ESP IDF use?
The UWB Module ESP IDF is built around the ESP32-S3-WROOM-1, from the ESP32 family.
How big is the UWB Module ESP IDF?
The UWB Module ESP IDF measures 71 × 64 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the UWB Module ESP IDF?
248 components, from 83 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 UWB Module ESP IDF design files?
From the victorstoica114/UWB_Module_ESP_IDF 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 UWB Module ESP IDF design in my own project?
The repository has no license, so all rights stay with victorstoica114. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the UWB Module ESP IDF 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.
