DFRobot micro: Breadboard micro:bit Expansion Board (Micro:bit Not Included)

The DFRobot micro: Breadboard micro Expansion Board is a solder-free development platform designed for building and debugging micro electronic circuits. It provides access to 19 micro I/O pins through pin-header and female-header connectors, allowing direct connection of electronic components on the included 16.2 × 7.2 cm breadboard. The board operates from 3.3–5 V and includes a Micro USB 5 V power interface, independent power switch, PWR indicator, and 2 onboard A/B buttons. It supports visual programming, Mind+, and Python, making it suitable for STEM education, circuit prototyping, and micro applications such as lighting control, smart doorbells, and temperature alarms.
