ESPectro32 Development Board

ESPectro32 is a powerful and feature-packed development board based on the ESP32 microcontroller by Espressif Systems that allows you to unleash your maker powers and make incredible things!

Don’t let the size fool you—complete with a plethora of features, including a display and a bunch of sensors, you’re gonna be surprised by what you can do with an ESPectro32, and then some! It supports external modules so you can extend it further.

Extensible and compatible, access all the ESP32 pins via Raspberry Pi-compatible breakout pins allowing you to extend it with various HAT boards. ESPectro32 also has unique edged pads breakout connected to all ESP32 pins; simply plug to the base board to extend ESPectro32's function. These unique pads also provide 5 alligator pins compatible for your experiment needs—no any soldering necessary. They are Micro:bit-based, so ESPectro32 is also Micro:bit-boards friendly.

With WiFi and Bluetooth support provided by ESP32, you can have ESPectro32 interact with other devices via the Internet. ESPectro32 has programmable 7x7 LED Matrix display and 2 buttons that can you can customize to many purposes to represent your wildest ideas!

ESPectro32 is designed to be easy to use by makers of all levels of expertise, but for those who love the hard way you can still tweak ESPectro32’s hardware side easily. Just attach or simply connect using jumper cable to your external devices.

Now go ahead and start making great things with ESPectro32!
