About the Esppdp PCB

Esppdp is an open source ESP32 PCB design by Spritetm, published on GitHub. It is a 4-layer board measuring 43 × 49 mm, with 55 components from 25 distinct parts.

Its main chip is the ESP-WROVER32, from the ESP32 family. Other key parts include the TP4056, HT7833_SOT89 and CH340C. By type, the board carries 27 resistors, 13 capacitors, 4 ICs, 4 transistors, 3 connectors and 2 diodes.

It belongs with the iot & wireless designs in this gallery.

From the project

ESP32-based PDP11 simulator, based onSimH

This is the source repository for esppdp, which is a tiny VT-102 scale model housing an ESP32 emulating a PDP11. You can connect a BlueTooth keyboard to it and play the original Tetris, or do some die-hard computing on 2.11BSD.

Well, someone had to put back the 'mini' in 'minicomputer', right?

Esppdp: common questions

What microcontroller does the Esppdp use?

The Esppdp is built around the ESP-WROVER32, from the ESP32 family.

How big is the Esppdp PCB?

The Esppdp measures 43 × 49 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Esppdp?

55 components, from 25 distinct parts. The full bill of materials is listed on this page.

Where can I download the Esppdp design files?

From the Spritetm/esppdp repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Esppdp design in my own project?

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

Can I test firmware for the Esppdp 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.
