SPM-ESPSM-V1: common questions

What microcontroller does the SPM-ESPSM-V1 use?

The SPM-ESPSM-V1 is built around the XIAO-HALF-HOLE-23P, from the ESP32 family.

How big is the SPM-ESPSM-V1 PCB?

The SPM-ESPSM-V1 measures 26.4 × 36.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the SPM-ESPSM-V1?

29 components, from 17 distinct parts. The full bill of materials is listed on this page.

Where can I download the SPM-ESPSM-V1 design files?

From the caketetu/SPM-ESPSM-V1 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the SPM-ESPSM-V1 design in my own project?

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

Can I test firmware for the SPM-ESPSM-V1 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.
