DESCRIPTION This TinyShield features four of our popular TinyShield Sensors on a single board! 9-Axis IMU: This sensor lets you measure 9 degrees of freedom (9DOF) with your TinyDuino and features the ST LSM9DS1 - a system-in-package featuring a 3D digital linear acceleration sensor, a 3D digital angular rate sensor, and a 3D digital magnetic sensor.The LSM9DS1 has a linear acceleration full scale of ±2g/±4g/±8/±16 g, a magnetic field full scale of ±4/±8/±12/±16 gauss and an angular rate of ±245/±500/±2000 dps. Temperature/Humidity: This sensor lets you measure temperature and humidity with the TinyDuino. Based around the Silicon Labs Si7020-A10 sensor, this allows for accurate temperature measurement (+- 0.4C) and precision relative humidity readings. Barometric Pressure: This sensor allows you to measure barometric pressure (and determine altitude) and temperature with your TinyDuino. Based around the Bosch BMP280 sensor, this allows you to measure barometric pressure with a +/- 1hPa absolute accuracy, and temperature with a +/- 1.0C accuracy. Ambient Light: This sensor features a TAOS TSL2572 Ambient Light Sensor, that approximates human eye response to light intensity under a variety of lighting conditions and through a variety of attenuation materials. Accurate ALS measurements are the result of TAOS’ patented dual-diode technology and the UV rejection filter incorporated in the package. In addition, the operating range is extended to 60,000 lux in sunlight when the low-gain mode is used.

Due to the low current, this board can be run using the TinyDuino coin cell option Pins Used A5/SCL - I2C Serial Clock line A4/SDA - I2C Serial Data line Dimensions 20mm x 20mm (.787 inches x .787 inches) Max Height (from lower bottom TinyShield Connector to upper top TinyShield Connector): 5.11mm (0.201 inches) Weight: 1 gram (.04 ounces) NOTES This TinyShield uses I2C communication and incorporates level shifters and a local power supply to ensure proper and safe operation over the entire TinyDuino operating voltage range up to 5V. You can also use this shield without the TinyDuino – there are 0.1″ spaced connections for power, ground, and the two I2C signals along the side of the TinyShield to allow you to connect a different system. Warning: Revision 4 boards have a mistake on the silkscreen, the pin marked VCC is actually SCL, the pin marked SCL is actually SDA, and the pin marked SDA is actually VCC. If you connect this up the way it is marked you will not damage the board.
