Xterminal: common questions

What microcontroller does the Xterminal use?

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

How big is the Xterminal PCB?

The Xterminal measures 33 × 33 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Xterminal?

67 components, from 33 distinct parts. The full bill of materials is listed on this page.

Where can I download the Xterminal 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 Xterminal 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 Xterminal 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.
