Keyestudio MEGA Protoshield/prototype expansion board V3 for Arduino+breadboard

The Keyestudio MEGA Protoshield V3 is a dedicated prototyping expansion board designed to plug directly into your Arduino MEGA 2560. It is an ideal tool for students, educators, and makers looking to design custom circuits, test SMD chips, or build temporary solderless layouts. With an included 170-hole breadboard and ample soldering space, this shield offers maximum flexibility for your electronics projects.

Custom circuit prototyping space

The shield features a large prototyping area with both connected and unconnected through-holes, allowing you to solder electronic components directly onto the board. For temporary testing, you can easily stick the included self-adhesive 170-hole mini breadboard onto this area.

Dedicated SMD chip support

A reserved surface-mount device (SMD) soldering position makes it easy to mount and test SMD integrated circuits directly on your Arduino MEGA. It also supports welding a standard 28-pin chip to accommodate more complex integrated designs.

Extended power and ground pins

To simplify your wiring, the board extends a dedicated row of power and ground through-holes. It breaks out the 5V, 3V, and Arduino Vin pins, providing ample power resources for all your external sensors and modules.

Onboard indicators and controls

This expansion board is equipped with a convenient physical reset button to easily restart your main controller. It also includes an integrated power LED and a D13 status indicator light for quick visual debugging.

Complete interface breakout

The shield extends out all of the control and power pins from the Arduino MEGA 2560 to accessible headers. It also breaks out the ICSP interface, ensuring you retain full programming and connectivity options for your projects.
