This page presents the TeensyWiNo hardware.

Quick description

The TeensyWiNo is a powerful shield for the PJRC Teensy 3.1/3.2. This all-in-one shield offers many possibilities: it enables wireless networking and add many sensors to the Teensy 3.1/3.2 module, while keeping a small form factor. Thanks to the Arduino ecosystem, the TeensyWiNo enables fast prototyping of Wireless Sensor Nodes, Internet of Things End-Devices or Connected Devices.

The TeensyWiNo includes:

  • A sub GigaHertz FSK/GFSK/OOK transceiver,
  • Many sensors:
    • Luminosity,
    • Temperature,
    • Pressure,
    • 3D accelerometer,
    • 3D gyroscopic sensor,
    • 3D magnetometer,
  • A Li-Po battery charger and gauge,
  • and a RGB LED.

Please refer to the Documentation page for more information on the the libraries recommended to use.

The TeensyWiNo has been designed by Snootlab.com after a technological transfert from the IRIT lab in Toulouse, France (Institut de Recherche en Informatique de Toulouse). The TeensyWiNo is available on the Snootlab.com on-line shop.


  1. Install the software development tools
  2. Play with the RGB LED
  3. Use the luminosity sensor
  4. Use the accelerometer sensor
  5. Connect an antenna to the TeensyWiNo
  6. Send and receive data between two or more TeensyWiNos
  7. Connect a Li-Po battery and save energy

Technical description

As seen on the wiring, the TeensyWiNo embeds:

  • 1 RFM22b (sub GigaHertz transceiver)
  • 1 TSL2561 (luminosity sensor)
  • 1 BMP085 (temperature and pressure sensor)
  • 1 LSM303CTR (3 axis accelerometer and magnetometer)
  • 1 L3GD20 (3 axis gyroscopic sensor)
  • 1 MAX17043 (Li-Po battery gauge)
  • 1 Li-Po charger based on a MCP73831
  • 1 RGB LED

Please refer to the Documentation page for the libraries to use. The TeensyWiNo’s sensors are connected to the MCU via the I2C bus, while the transceiver is connected via the SPI bus. Sensors and transceiver are powered via the Teensy 3.3V output (internally regulated).
