Scooterputer™ Sensor Shield

Scooter. Motorcycle. Snowmobile. ATV. Boat. E-Bike. The power of GPS. The ease of Arduino®. Pop this sensor packed shield onto an Arduino microcontroller for a powerful, high-tech dash for your ride. The Scooterputer gathers vehicle and travel information which can be viewed on one of our GLCD Displays, or on your smartphone using one of our apps and optional Bluetooth Module. Includes a fast, reliable GPS unit and on-board screw terminals for optional magnetic sensor, external ignition pulse sensor, and additional temperature sensors. All features needed for a fully operational Scooterputer are provided; but remember - open source hardware and software gives you the power to customize and adapt to meet your personal specifications. Use Scooterputer to get started, then add your own sensors and modify our software programs to make it your own.

Bluetooth RN42 Module

Add our Bluetooth RN42 Module to your Scooterputer Sensor Shield to use your own Android smartphone as a Scooterputer dashboard. Our smartphone apps display the same information as our GLCD Display products. Or use two Bluetooth Modules as a cable replacement - one on the Scooterputer as master and another on the GLCD Display as slave. And it's easy to interface with any microcontroller: just 2 pins, TX and RX at 5v or 3.3v levels, are needed for data exchange.
