XSense: common questions

What microcontroller does the XSense use?

The XSense is built around the ESP32-PICO-D4, from the RP2040/RP2350 family.

How big is the XSense PCB?

The XSense measures 30.8 × 46.9 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the XSense?

74 components, from 34 distinct parts. The full bill of materials is listed on this page.

Where can I download the XSense design files?

From the lithiumice/XTerminal repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the XSense design in my own project?

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

Can I test firmware for the XSense without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
