  • Bring oscillation source Audino 9012 drive Work Voltage:3.3V-5V Set bolt hole, easy to assemble PCB Dimension:3.3cm*1.3cm It and your Arduino will be able to play melodies. This is a small buzzer for the Sensor Shield. It creates different sound based on the different frequency of I/O toggling. Pin Definition : Vcc : 3.3V-5V GND : The Ground I/O : I/O Interface of SCM
  • The cable is easiest way ever to connect to your microcontroller/Raspberry Pi/WiFi router serial console port. Inside the big USB plug is a USB<->Serial conversion chip and at the end of the 36" cable are four wire - red power, black ground, white RX into USB port, and green TX out of the USB port. The power pin provides the 5V @ 500mA direct from the USB port and the RX/TX pins are 3.3V level for interfacing with the most common 3.3V logic level chip-sets.
  • CH340 is a USB bus convert chip and it can realize USB convert to serial interface, USB convert to IrDA infrared or USB convert to printer interface. In serial interface mode, CH340 supplies common MODEM liaison signal, used to enlarge asynchronous serial interface of computer or upgrade the common serial device to USB bus directly. More detail about USB convert to printer interface please referring to the second manual CH340DS2. In infrared mode, add infrared transceiver to CH340 can compose USB infrared adapter, realize SIR infrared communication.
  • The MB102 is a breadboard power supply module manufactured by the YuRobot . This module has the marking 545043 and MB V2 on the printed circuit board (PCB). It provides dual 5 V and 3.3 V power rails, and has a multi-purpose female USB socket.
  • Just like a joystick on game console. you can control x, y and z dimensions input by this joystick module. It can be considered as combination of potentiometers and one button. Data type of the x, y dimensions are analog input signals and z dimension is digital input signal. thus the x and y ports connect to analog pins of Sensor Shield, while z port connects to digital pin. When using, it can connect with Arduino sensor shield,and connect Arduino corresponding pins through Arduino sensor cables.
    • Drive a 2-phase bipolar stepper motor or two DC motors with the L298 dual H-Bridge chip, mounted on this handy breakout board along with all necessary peripherals!
    • It is ideal for robotic applications and well suited for connection to a microcontroller requiring just a couple of control lines per motor. It can also be interfaced with simple manual switches, TTL logic gates, relays, etc.
  • 4-channel relay output modules, relay output contacts 250A 10A. Input IN1, IN2, IN3, IN4, the signal line LOW effective. VCC, GND power input, can relay a separate power supply relay power input of JD-VCC. Uses: support all MCU control. the industrial sector PLC control smart home control Wiring: VCC: positive power supply system GND: System power supply negative IN1 - IN4: relay control ports

  • 1.Output Current: 1.5A (min), 2.2A (typ) 2.Input-output voltage differential (VI-VO): 40Vdc (max) 3.Adjustable output voltage range: 1.2 ~ 37V 4.Operating temperature: -55 Celsius ~ 150 Celsius 5.Current output: 1.5A 6.Voltage Input: 4.2 ~ 40 V 7.Operating temperature: 0 Celsius ~ 125 Celsius 8.Characteristic frequency: 100MHz 9.Module size: 35.6 mm x16.8 mm 10.Input Method: VIN input is positive, GND Input Negative 11.Output: VOUT output positive, GND output negative
  • Reading Sensing and Controlling current flow is a requirements in a wide variety of application including, over-current protection circuits, switching mode, battery chargers, power supplies, digital watt meter and programmable current source, etc.. The ACS721 current reading module is based on ACS712 Sensor which can detect AC, DC current signal accurately. The maximum AC / DC can be detected using ACS712 will reach 30 amp and present current signal can read via analog IO port of Arduino, Product available for this module are 30A, 20A, 5A. for this demonstration we will used the ACS712 30A.
