- The keyes prototype expansion board is an expansion board used in conjunction with the Keyes UNO R3 development board. It is used to build a circuit prototype. You can directly solder components on the board or connect the circuit through the mini breadboard above. The breadboard and the circuit board are connected by double-sided tape, and the breadboard and the circuit board are separated when sold. The keyes prototype expansion board is equipped with a reset button and a power indicator, which can be used directly. All pins and power have been drawn out, which is very suitable for building circuit prototypes with Arduino.
