ESP-HI-PLUS Desktop Sub module: common questions

What microcontroller does the ESP-HI-PLUS Desktop Sub module use?

The ESP-HI-PLUS Desktop Sub module is built around the RP2040, from the RP2040/RP2350 family.

How big is the ESP-HI-PLUS Desktop Sub module?

The ESP-HI-PLUS Desktop Sub module measures 60 × 43 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP-HI-PLUS Desktop Sub module?

61 components, from 33 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 ESP-HI-PLUS Desktop Sub module design files?

From the dyu134/ESP-HI-PLUS 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 ESP-HI-PLUS Desktop Sub module design in my own project?

The repository has no license, so all rights stay with dyu134. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the ESP-HI-PLUS Desktop Sub module 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.
