The Teensy 3.1/3.2 is one of the best Arduino compatible boards out there. With projects ranging from LED walls to electric vehicle controllers and not lacking a large array of wonderful libraries, it has enabled hundreds of makers and tinkerers to create awesome stuff. Now you can take your project anywhere with mobile capability and GPS positioning! Small enough to fit into bicycle handlebars, light enough to be mounted to small drones and RC cars, powerful enough to read and write in CAN networks; the TinyTracker is versatile for many applications, yet priced similarly to large shields.

• Weight: approx 10 grams without battery and antennas
• Approximate consumption: <300mA @ 10 second continuous data posts, <100mA @ 5 minute continuous data posts
• Optional 10DOF MEMS sensor board (accelerometer, gyro, compass, altimeter)

Teensy 3.1/3.2 I/Os available after installation

• One Serial port (Port #2)
• SPI Port
• I2C Ports
• 6x PWM, 5x Touch, or all Analog I/Os
• bottom pads are accessible and can be used for the 10DOF sensor board

Use cases (what we've tested or currently running)

• Electric bicycle rental security, incl. sending CycleAnalyst readouts (on Serial Port #2) to a remote server
• Mounted to a DJI Phantom 2 in case of loss, sends position to server every 10s, SMS position on demand (could read CAN data from Naza, not implemented in software yet)
• Connected to a Nissan Leaf CAN-BUS for battery/charge data and remote commands
• Daily tracking a Ford delivery van, incl. battery state, fuel state, other CAN data
• Mounted inside a carrying case with very expensive audio equipment in case of theft

Please note: The kit is offered built and functionally tested and ready with antennas, but the Teensy is not included (unless added as an option). Some simple soldering is required (header pins), although we can solder the two boards together upon request. You will need a Nano SIM with a basic 2G data plan. Sample code for GSM/GPS to SQL server functions is supplied, but CAN and other libraries will need to be applied by you. We are happy to recommend known working libraries.
