Specifications:

The MKR PROTOSHIELD L is designed for use with MKR boards, providing a prototyping platform that plugs onto your MKR board using provided female/male headers. This shield enhances the utility of MKR boards by offering a duplicate breakout for each pin along with many solderable through-holes on a standard 0.1” grid (2.54mm), allowing for easy circuit assembly and experimentation.

Technical specifications for the MKR PROTOSHIELD L include:

• Digital I/O Pins: 21
• PWM Digital I/O Pins: The actual number depends on the board it is used with
• Analog Input Pins: 7
• Analog Output Pins: The number depends on the board
• DC Current per I/O Pin: This varies depending on the board
• DC Current for 3.3V Pin: Also varies depending on the board
• DC Current for 5V Pin: Varies with the board
• Length: 61.5 mm (for one version) and 80 mm (for another larger version)
• Width: 25 mm (for one version) and 50 mm (for the larger version)
• Weight: 13 grams (for the standard version) and 19 grams (for the larger version)

Data Logger with MKR Proto Shield

Applications and Projects:

The MKR PROTOSHIELD L, combined with MKR boards, offers a broad spectrum of potential applications, particularly in areas such as data logging, environmental monitoring, and IoT devices, thanks to its compatibility with various sensors and actuators. Here are a couple of project examples and applications that leverage the capabilities of the MKR PROTOSHIELD L and related shields:

• Environmental Data Logger: Utilizing the MKR SD Proto Shield, you can create a project that captures environmental data like temperature and wind speed at regular intervals and stores this data on an SD card for later analysis. This setup is particularly useful for weather monitoring applications where real-time data transmission is not required. After the data collection period, the SD card can be retrieved and the data analyzed to identify environmental patterns.
• Relay Control: Another practical application involves using the MKR Relay Shield to control high-power components, such as lights or motors, via relays. This project can teach you the basics of relay operation and how to activate them through your MKR board. It involves simple programming that toggles the relays on and off, which can be adapted to control various devices in home automation or industrial settings.
• GPS Tracking: The MKR GPS Shield can be utilized to develop a GPS tracking system. This project involves capturing geographic location data and other related information such as altitude and speed. This kind of application is useful for tracking the position of vehicles or other assets in real-time. Additionally, the GPS data can help in creating location-based services or for logging routes traveled.
