The RTC module is a member of Twig. It is based on the DS1307 clock chip which supports the I2C protocol. It uses a Lithium ce...

The AM2302 is a wired version of the DHT22, in a large plastic body. It is a basic, low-cost digital temperature and humidity sensor. It uses a cap...

This is a 12-step rotary encoder with a nice 'clicking' feel. It's breadboard friendly, and has a pretty handy select switch (by pushing in on the ...

This is 30 feet of conductive thread spun from stainless steel fiber and wound on a plastic bobbin. Use it to sew up all of your e-textile projects...

As an expansion board, Base Shield v2 has many Grove connectors, making it convenient for you to use Grove products together. And It is compatib...

Rotary encoders are used similarly to potentiometers. They're different from potentiometers in that an encoder has full rotation without limits....

The Arduino Ethernet Shield 2 connects your Arduino to the internet in mere minutes. Just plug this module onto your Arduino Board, connect it to y...

This temperature & humidity sensor provides a pre-calibrated digital output. A unique capacitive sensor element measures relative humidity and...

This is a breakout board for Honeywell's HIH-4030 humidity sensor. The HIH-4030 measures relative humidity (%RH) and delivers it as an analog ou...

New! we are now carrying an 'assembled' version of this shield, with all the components pre-soldered. NOTE: You will only need to solder on either...

The new version of XBee Shield is a standardized and stackable shield compatible with Arduino. You can easily stack any modules from the Bee serie...

Trinket may be small, but don't be fooled by its size! It's a tiny microcontroller board, built around the Atmel ATtiny85, a little chip with a lot...

Finally we have an I2C-interface temperature & humidity sensor in a nice enclosed style. This sensor contains a DS18B20 temperature sensor and ...

This is the new-released SD card V4.0 shield. It provides a storage space for your Arduino. Users can read/write SD card via Arduino's built-in SD ...

The Motor Shield is a driver module for motors that allows you to use Arduino to control the working speed and direction of the motor. Based on th...

This is the LilyPad revision of our FTDI Basic. It is the same as our other FTDI Basic, but has a purple LilyPad board which is half the thickne...
