The Capacitive Touch Keyboard uses the MPR121 IC from Freescale with 12 touch sensitive keys/pads. The MPR121 IC detects the touch by measuring change in capacitance of touch pads and talks via I2C interface. It’s designed to work with both 3.3V and 5V systems and has all the necessary level shifting and regulator on board.
The ADXL345 3-AXIS (±2g/±4g/±8g/±16g) Module is a beautiful addition to our offerings of accelerometer sensors. Interfacing via SPI (3 or 4 wire) or I2C digital Interface. Usable at 3.3V or 5V with on-board regulator for 3.3V and level-shifting circuit.
This is a module for ACS712 ±20A hall-effect based AC/DC Current Sensor with just 1.2 mΩ resistance of input path from Allegro. And outputs a proportional analog voltage on Vo pin of 185 mV/A centered at 2.5V with a typical error of ±1.5%. It operates from 4.5 V to 5.5 V and is intended for use in 5 V systems.
The BMP085 from Bosch is the best low-cost sensing solution for measuring barometric pressure and temperature as well as altitude. Interfaces to the MCU via I2C interface and is designed to work with 3.3V and 5V systems, equipped with 3.3V regulator, I2C level shifter and the pull-up resistors for the I2C pins.
This is a DS1307 based Real Time Clock module that keeps track of the Date / Time even after the system is powered off or reprogrammed . Comes with a CR1220 battery to retain the Date / Time info after power off for up to 5 years. And Communicates with the Microcontroller via I2C interface.
This board consists of the FT232RL IC with pin header & screw terminals for the UART and other signals from FT232RL. Also it has a dedicated 3.3V regulator. Can run on 3.3V and 5V logic levels which can be selected via the Jumper. And all the pins of FT232RL brought out on the 14 pin header.
The TCS3200 Module is a color sensor designed to detect the intensity of colour of light incident on it. It outputs a square waveform, with frequency proportional to the intensity of incident radiation and with the help of 4 filters Red , Green, Blue and Clear we can determine the colour. This module comes with 4 white LEDs for illuminating the object to...
