Universal programmer to flash firmware to Flyport module while plugged on a Nest carrier board.

General purpose screw terminal with Grove Connector

This new version of button twig contains one independent button, which are configured with pull-down resistor.

The Light sensor module uses the GL5528 photoresistor to detect the light intensity of the environment.

The ingenious PCB design enables you to bend the LED to any position you want, which makes it easy to use it standalone, horizontal or Panel Mount

Chainable RGB LED Twig can provide constant current drive and modulated output of 256 gray

Control color and luminance of a single color or RGB led strip

The angular range is 300 degrees with a linear change in value.

Hall effect sensor

The I2C Touch Sensor is based on FreeScale MPR121, to feel the touch or proximity of human being fingers. This sensor include 2 parts: one Touch Sensor controller, and 4 finger feelers.

This is a simple to use PIR motion sensor with Grove compatible interface. Simply connect it to Stem shield and program it, when anyone moves in its detecting range, the sensor outputs HIGH on its SIG pin.

This Moisture Sensor can be used to detect the moisture of soil or judge if there is water around the sensor, let the plants in your garden reach out for human help.

High accuracy temperature and humidity sensor. It consists of a capacitive sensor element used for measuring relative humidity and a negative temperature coefficient (NTC) thermistor used for measuring temperature.

The Grove - Gas Sensor(MQ5) module is useful for gas leakage detecting(in home and industry). It can detect LPG, natural gas, town gas and so on.

Grove - 3-axis Gyro module based on ITG 3200. It is the world’s first single-chip, digital-output, 3-axis MEMS motion processing gyro optimized for gaming, 3D mice, and motion-based remote control applications for Internet connected Digital TVs and Set Top Boxes.

3-Axis Compass uses I²C based Honeywell HMC5883L digital compass.
