Jlcpcb 1x1: common questions

What microcontroller does the Jlcpcb 1x1 use?

The Jlcpcb 1x1 is built around the -, from the ESP32 family.

How big is the Jlcpcb 1x1 PCB?

The Jlcpcb 1x1 measures 134 × 114 mm, has 8 copper layers and is 1.6 mm thick.

How many components are on the Jlcpcb 1x1?

105 components, from 44 distinct parts. The full bill of materials is listed on this page.

Where can I download the Jlcpcb 1x1 design files?

From the t-dsp/t-dsp_core repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Jlcpcb 1x1 design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Jlcpcb 1x1 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.
