About the ESP32-S2 DEV PCB

ESP32-S2 DEV is an open source ESP32 PCB design by hwreverse, published on GitHub under the MIT license. It is a 2-layer board measuring 27.9 × 88.9 mm, with 32 components from 24 distinct parts.

Its main chip is the esp32-s2-wroom, from the ESP32 family. Other key parts include the AP1117-33, MCP73831-2-OT and 240x240TFT. By type, the board carries 10 capacitors, 7 resistors, 5 connectors, 4 ICs, 3 switches and 3 diodes.

It belongs with the dev boards & breakouts, power & battery and sensors designs in this gallery.

HWR0's Shield Designs for the MorphESP 240 by @ccadic

- Next evolution of the Gamepad Shield in a new design with two additional analog josticks and a I2C Gyroscope + Accelerometer integrated circuit for Position & Inertia capture. - 2x4 Button Gamepad Shield and connection to optional Buzzer ready to be fabricated and assembled by the PCBA service of your choice. It can also be soldered by hand as I used only 0805 and SOT-23 footprints for the passives and the transistor (on the backside). Pushbuttons are classic, comfy 12mm x 12mm x 4.3/5mm units, that won't use that much your fingertips.

ESP32-S2 DEV: common questions

What microcontroller does the ESP32-S2 DEV use?

The ESP32-S2 DEV is built around the esp32-s2-wroom, from the ESP32 family.

How big is the ESP32-S2 DEV PCB?

The ESP32-S2 DEV measures 27.9 × 88.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP32-S2 DEV?

32 components, from 24 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 ESP32-S2 DEV design files?

From the hwreverse/MorphESP240_Shields repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the ESP32-S2 DEV design in my own project?

Yes, under the terms of its MIT license, which hwreverse chose for the repository.

Can I test firmware for the ESP32-S2 DEV 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.
