  • Tiny and lightweight with high output power. Servo can rotate approximately 180 degrees (90 in each direction), and works just like the standard kinds but smaller. You can use any servo code, hardware or library to control these servos. Good for beginners who want to make stuff move without building a motor controller with feedback & gear box, especially since it will fit in small places. It comes with a 3 horns (arms) and hardware. Specifications • Weight: 9 g • Dimension: 22.2 x 11.8 x 31 mm approx. • Stall torque: 1.8 kgf·cm • Operating speed: 0.1 s/60 degree • Operating voltage: 4.8 V (~5V) • Dead band width: 10 µs • Temperature range: 0 ºC – 55 ºC
  • DS18B20 Temperature Sensor Module

    SKU: E-246 100.00 +GST
    Introduction: These 3-wire digital temperature sensors are fairly precise (±0.5°C over much of the range) and can give up to 12 bits of precision from the onboard digital-to-analog converter. They work great with any microcontroller using a single digital pin, and you can even connect multiple ones to the same pin, each one has a unique 64-bit ID burned in at the factory to differentiate them. Usable with 3.0-5.0V systems. Technical Details: Technical specs: Usable temperature range: -5° to 90°C (-23°F to 194°F) 9 to 12 bit selectable resolution Uses 1-Wire interface- requires only one digital pin for communication Unique 64 bit ID burned into chip Multiple sensors can share one pin ±0.5°C Accuracy from -10°C to 85°C Temperature-limit alarm system Query time is less than 750ms Usable with 3.0V to 5.5V power/data
  • The USB to RS485 module is a cost-effective way to convert RS485 industrial buses to a USB interface. When connected to a PC USB port the USB to RS485 module is automatically detected and is installed as a native COM port which is compatible with any existing serial communication application. Multiple modules can be installed when using USB hubs thus allowing a hassle-free configuration of a multi serial system. Features
    • Reliable RS485 link
    • Automatic Switching between Transmit/Receive mode of RS485.
    • Twisted pair cable can work upto 1.2 Km distance.
    • Ground Output for wire shielding.
    • USB Powered
    • USB Port Plugabble type
    • Designed for industrial environment
    Specifications
    • Any baud rate from 1200 bps to 115 kbps
    • Current: 100mA current at 5V DC taken from PC’s USB Port
    • Modes: RS-485 Half Duplex (2-wire)
    • Built in terminal resistor of 120R Ohm
    • Length of twisted pair cable maximum can be 1.2 Km (Kilometer) Maximum
    • Cable type for optimal range: Two core, Twisted Pair Shielded type, D and D- should be twisted with each other to get optimal range
  • Description: This Ceramic Piezo Vibration Piece Sensor buffers a piezoelectric transducer that responds to strain changes by generating a measurable output voltage change which is propotional with the strength of vibration.So you can know the extent of vibration. Different from digital vibration sensor that only accounts times, this analog one can tell extent of vibration. When the piezoelectric ceramic shocking will generate an electrical signal, Arduino Controller analog port can be perceived slight vibration signals, Also can be realized with vibration interactions related works, such as electronic drums. Marking "A" represents the module is a Analog Sensor, the other side graph represents function of the sensor. Easy identification!  
  • This is an elegant and innovative protective case designed specifically for the Raspberry Pi 2 Model B. Based on the best-selling SB Components' Model B case this two-piece injection-molded ABS enclosure incorporates snap-fit mounting points that hold the Pi securely in place. It provides tough protection for the Raspberry Pi Model B along with access to all the PI consumer ports as well as DSI, camera and GPIO connectors.
  • This is a breakout board for Freescale’s MPR121QR2. The MPR121 is a capacitive touch sensor controller driven by an I2C interface. The chip can control up to twelve individual electrodes, as well as a simulated thirteenth electrode. The MPR121 also features eight LED driving pins. When these pins are not configured as electrodes, they may be used to drive LEDs.
  • MF RC522 is a highly integrated read and write card chip applied to the 13.56MHz contactless communication.It is a low-voltage, low-cost, and small-sized non-contact card chip, a best choice for intelligent instrument and portable handheld devices. The MF RC522 uses advanced modulation and demodulation concept which fully presented in all types of 13.56MHz passive contactless communication methods and protocols. In addition, it supports rapid CRYPTO1 encryption algorithm to verify MIFARE products. MFRC522 also supports MIFARE series of high-speed non-contact communication, with a two-way data transmission rate of up to 424kbit/s. As a new member of the 13.56MHz highly integrated reader card series, MF RC522 is much similar to the existing MF RC500 and MF RC530 when there are also great differences. It communicates with the host machine via the serial manner which needs less wiring. You can choose between SPI, I2C and serial UART mode (similar to RS232), which helps reduce the connection, save PCB board space (smaller size), and reduce cost.
