P-Bit: The Environmental Mini Computer for STEAM & IoT Projects

The P-Bit is a powerful, compact environmental mini-computer designed for hands-on learning, rapid prototyping, and STEAM education.

Built around the ESP32, it integrates multiple sensors, RGB LEDs, a rotary encoder, a buzzer, and a vivid 1.8" TFT screen — all in a transparent 2 mm acrylic enclosure, ready to use or customise.

🔍 Key Features

• Ready-to-use and fully assembled

• Powered by a dual-core ESP32 microcontroller

• Includes built-in LDR, DHT11, and MEMS microphone

• Bright 1.8" TFT colour display (128x160 resolution)

• Interactive control via rotary encoder

• Visual & audio feedback with 3 RGB LEDs and piezo buzzer

• Crowtail-compatible: 3 I2C + 3 GPIO ports

• Arduino IDE programmable

🧠 For Makers, Educators & Experimenters

Whether you're a maker, a student, or an educator, the P-Bit offers a seamless experience from day one.

It runs on 4x AAA batteries or via USB-C (5 V) and comes with a pre-installed firmware that allows immediate interaction with the built-in sensors.

🔌 Crowtail Compatibility for Easy Expansion

The P-Bit is fully compatible with Elecrow’s Crowtail ecosystem, enabling effortless plug-and-play expansion.
With 3 I2C ports (yellow) and 3 GPIO ports (black, red, blue), you can connect a wide variety of Crowtail modules like:

• CO₂ and air quality sensors

• Turbidity and TDS sensors

• Motors, pumps, LEDs and more

🔧 Fully Programmable via Arduino IDE

Once you're ready to customise or scale your project, the P-Bit becomes a versatile platform for:

• Environmental data logging

• IoT prototypes

• STEAM workshops and classes

• Custom interactive installations
