With a High-Resolution IPS Color Display & CircuitPython Support

While there are many ESP32 dev boards on the market, we here at Morpheans found ourselves lamenting the scarcity of such boards for the new ESP32-S2. So we decided to build one. Introducing MorphESP 240, an easy-to-use, Arduino- and CircuitPython-compatible, open hardware ESP32-S2 dev board with a built-in high-resolution, IPS-color display.

Our target was minimalism with room to grow, and—after squeezing the following specs into a 20 g, 89 x 28 x 6 mm package—we believe we’ve hit the bullseye:

• An ESP32-S2 WROOM with
  • A 240 MHz single-core microcontroller
  • 128 KB of ROM
  • 320 KB of SRAM
  • 802.11 b/g/n/ 2.4 GHz Wi-Fi
• An on-board, SPI-driven, 240 x 240 pixel ST7789 display
• A classic, multi-color WS2812B RGB LED
• A built-in, JST-connected battery with a USB charging module
• A 5 V to 3.3 V regulator to feed additional modules
• Plenty of GPIOs to play with

A Standalone Board for Education & Innovation

Whether you’re a student, a maker, or a product designer, MorphESP 240 provides an affordable, versatile, fully-integrated platform with Wi-Fi connectivity. Learn, experiment, and create while avoiding overpriced, proprietary hardware with limited functionality.

The world of possible applications for MorphESP 240 includes IoT gateways, sensor networks, test and measurement equipment, wireless input devices, radio communication platforms, media streaming appliances, imaging technologies, and prototyping projects for just about anything.

Dev Shield Included With Every MorphESP 240

All MorphESP 240 boards come with a bonus Dev Shield. The MorphESP 240 dev shield has everything you need to accelerate your prototyping work: all GPIO and grouped (I²C and SPI) connectors—naturally—but also an on-PCB 868/916 MHz UHF antenna and an RFM95 LoRa® transceiver footprint so you can easily test long-range IoT applications.

Open Hardware

MorphESP 240 is open source to its core. Please help yourself to our schematics; our KiCAD project source; and the DXF, STL, and Solidworks files you’ll need if you want to lasercut or 3D print yourself an enclosure. And if you want to fabricate your own dev shield, have at it! We only ask that you let us know if you make any improvements.

Develop with CircuitPython or Arduino

MorphESP 240 is fully compatible with both Arduino and CircuitPython, so you can take advantage of (and contribute to!) the collective work of C++ and Python developers around the world. Whether you’re learning or creating, you’ll be able to reuse thousands of pre-made tools and libraries with very little adaptation.

Help Us Build a Community

We invite you to help us deliver a cool, all-in-one device with fully transparent source materials: code, 3D models, project files, Gerbers, and anything else we happen to write down on our way to production. We’re looking to build a community of makers who are passionate about this platform, and we very much hope you’ll be a part of that community. We’ve been rowing hard, and we’re almost home, but we need your hands on an oar if we’re going to bring this ship to port.

Make Your Own Enclosure

We designed the above laser-cut acrylic, open-frame enclosure to protect your MorphESP 240 from the dangers inherent in your pocket, your shoulder bag, and your benchtop. While we are not currently selling the enclosure, we invite you to make one yourself!
