Microbots has introduced the CodeCell, a tiny ESP32-based development board with a footprint of just 18.5mm square, designed for makers, educators, and hobbyists. This compact board is perfect for small robotics projects, offering Wi-Fi and Bluetooth LE capabilities through its Arduino-compatible ESP32-C3 microcontroller.
The CodeCell features 6 programmable GPIO pins and 2 I2C pins that can also function as GPIOs, providing flexibility for connecting sensors, actuators, and other modules. It includes a BQ24232 battery management chip with dynamic power-path control, allowing the device to operate while charging. Power options include a USB-C port or a LiPo battery connector, making it convenient for recharging and continuous use.
One of its standout features is the VCNL4040 light sensor, capable of detecting ambient light and proximity up to 20 cm, making it ideal for light-based interactions and proximity detection. For advanced motion sensing, an optional BNO085 sensor adds 9-axis functionality, combining an accelerometer, gyroscope, and magnetometer. This sensor uses sensor fusion algorithms to provide motion data such as roll, pitch, yaw, and even step counting, opening up exciting possibilities for robotics and wearable devices.
With its small size, powerful features, and flexibility, CodeCell is a versatile platform for developing IoT devices, robotics, and wearable tech. Whether you’re just starting or an experienced maker, CodeCell gives you the tools to bring your creative projects to life.
