BREAKING NEWS !!!!! We started a Crowdsupply campaign because of many requests. You can get a fully assembled product here: https://www.crowdsupply.com/morpheans/morphesp-240
Esp32-S2 dev board with 240x240 IPS display
A powerfull dev board with the ESPRESSIF™ ESP32-S2®, a high resolution display, a RGB LED, a battery charger and a bunch of GPIOs.
There are many ESP32 board on the market but very few with the new ESP32-S2 which handles USB communications, new cryptography functions. We wanted to have a board with a built in hi-resolution IPS Color Display. After years playing with previous versions of the ESP32, building security devices, text pagers, we just wanted to go one step further and have our opensource circuit.
We wanted to have something minimalistic but expandable so we chose the ESP32 S2 WROOM component , a classic WS2812B RGB LED, a classic 5v to 3.V voltage regulator. We wanted something extremely easy to use therefore fully compatible with ARDUINO® IDE plateform. We also wanted something simple to handle as a first crowdfunding project.

Questions
How big is the ESP32-S2-WROOM PCB?
It measures 27.9 × 92.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESP32-S2-WROOM use?
29 parts, built around the ESP32-S2-WROOM-N4, TLV75733PDBV, BAT54C and WS2812B. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ESP32-S2-WROOM KiCad files?
From the ccadic/ESP32-S2-DevBoardTFT repository on GitHub, at the commit this page was made from: the board is hardware/V3.1-LAST/ESP32-S2-WROOM.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32-S2-WROOM design in my own project?
Its repository states no licence, so its author keeps all rights: ask ccadic before reusing the design.
