About the Esp-3dp PCB

Esp-3dp is an open source ESP32 PCB design by smkent, published on GitHub under the CC-BY-SA-4.0 license. It is a 2-layer board measuring 66 × 32 mm, with 53 components from 35 distinct parts.

Its main chip is the ESP32-C3-Super-Mini-Castellated-SMD, from the ESP32 family. Other key parts include the TPS54202DDCR, TPS563201 and SN74LVC1T45Z6. By type, the board carries 16 capacitors, 10 resistors, 7 LEDs, 6 connectors, 4 ICs and 3 diodes.

PCB designs

A monorepository of my PCB designs created with [KiCAD][kicad] 8.

Custom symbols and footprints are located in [libraries][dir-libraries], which is shared between PCB projects using [${KIPRJMOD}][docs-kiprjmod].

Individual PCB projects (e.g. .kicadpro and friends) are located within within [pcb][dir-pcb] for active projects, or [pcb-archived`][dir-pcb-archived] for archived projects.

Esp-3dp: common questions

What microcontroller does the Esp-3dp use?

The Esp-3dp is built around the ESP32-C3-Super-Mini-Castellated-SMD, from the ESP32 family.

How big is the Esp-3dp PCB?

The Esp-3dp measures 66 × 32 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esp-3dp?

53 components, from 35 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-3dp design files?

From the smkent/pcb 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-3dp design in my own project?

Yes, under the terms of its CC-BY-SA-4.0 license, which smkent chose for the repository.

Can I test firmware for the Esp-3dp 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.
