COMBO SENSOR TINYSHI ELD (13-DOF) 9-AXIS,
TEMPERATURE/HUMIDITY , PRESSURE, LI GHT
ASD2511-R-N-T-P-L
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.
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.

NOTES
o
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.
