Development Boards
Prototype electronics and build simple automation systems with the configurable inputs and outputs on these boards. Monitor both digital and analog devices, including proximity and temperature sensors, and control basic outputs, such as changing the speed of a servomotor or turning LEDs on and off. Their open-source software makes programming and troubleshooting convenient. Choose a board whose operating voltage can support the other devices you’re connecting to.
Boards with headers are good for making quick connections. Plug them in directly to breadboards, or connect them using jumper wire.
Boards without headers require making your own soldered connections. Use them for permanent or long-term installations.
Sets include the hardware and components needed to start building simple automation systems. Uno starter kits include an instructional project book, making them good for learning the basics of coding and electronics.

Mini Development Boards
Often used for rapid prototyping of electronic systems, these boards have various inputs and outputs to monitor sensors and control actuators. They’re smaller than other development boards, so they save space in your setup—while still having the same basic functions. Solder components directly to these boards for permanent or long-term installations. Attach headers for quick connections as you prototype. The operating voltage should support the other devices you’re configuring and connecting them to.
To program, attach a header to the board and connect the programming module (each sold separately). Connect the module to your computer using a USB cord (sold separately) and transfer your code. Once the board has been programmed, the module can be removed.
