ESP-HI-PLUS: common questions
What microcontroller does the ESP-HI-PLUS use?
The ESP-HI-PLUS is built around the RP2040, from the RP2040/RP2350 family.
How big is the ESP-HI-PLUS PCB?
The ESP-HI-PLUS measures 58 × 35 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the ESP-HI-PLUS?
83 components, from 58 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 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 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 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.
