Product Details
Example Uses
- Smart-home and automation projects; hands-on making; teaching kids and adults the basics of robotics; a wide range of DIY builds
- Robotics: servos, steppers, and varied sensors
- IoT projects with cloud connectivity
- Educational labs for electronics and programming
- Industrial controllers over RS-485
- Up to eight DS18B20/DS1820 temperature sensors
- One DHT20/21/22 humidity/temperature sensor
- Simple, direct hookup for up to four 9 g servos right on the board—no extra power fuss
- Display support over SPI and I²C
Built-in lightweight scripting language (BASIC-like): write scripts directly on the device, with syntax checking plus color highlighting for keywords and data—making coding and error-spotting easy. This is such a major advantage that we’ll dedicate a full Software section to the language, its commands, and how scripts interact with the board and run on-device.
Easy control from a mobile app or desktop software.
Cloud data storage and remote access: store data on a server and access/control your board from anywhere.
