Development Board Kit Upgraded RFID Starter Stepper Motor Learning Module

Item Type: Development Board Kit <br>Material: Resin <br>Working Voltage: 5V <br>Input Voltage: 7-12V (recommended) <br>UT Voltage: 6-20V <br>Digital Input/Output Pins: 54 Channels <br>Analog Input Pins: 16 <br>3.3V Pin Current: 50mA <br>Flash Memory: 256kb, of which the boot program occupies 8kb <br>SRAM: 8kb <br>EEPROM: 4kb <br>Clock Frequency: 16MHz <br>Purpose: Electronics, programming introductory learning kit<br>1、Completely solve the incompatibility and instability of traditional 2560 boards on for win7/win8 systems <br>2、The main control chip for 16AU has been retained and the USB chip 16u2 has been replaced <br>3、In most applications, these USB interface chips are only used for serial port "flashing" and communication. Using a professional USB chip can not only reduce the cost, but also meet the application <br>4、The external interface adds SDA and SCL on the basis of the 2011 version (position on the left side of AREF). The I0REF interface can provide a voltage reference to the shield. And for the compatibility of future series products, a port is reserved on the left side of IOREF <br>5、The RESET circuit is improved compared to the 2011 version. Prevent accidental reset of RESET, RESET circuit is more stable1. Can be powered by USB connection or external power supply, and the power supply will be switched automatically. <br>2. The development board can run with an external power supply voltage of 6?20V. If the power supply voltage is less than 7V, the voltage that the 5V pin can provide may be less than 5V, which may cause the development board to not operate stably. If the input voltage exceeds 12V, the voltage regulator may overheat and damage the development board. The recommended operating voltage range is 7?12V.<div>1 x For Improved Version</div><div>1 x USB Cable</div><div>1 x 30 Bread Lines</div><div>1 x YB-102 830 Holes Bread Wire</div><div>5 x Yellow LED</div><div>5 x Red LED</div><div>5 x Green LED</div><div>10 x 1K Resistor</div><div>10 x 10K Resistor</div><div>10 x 220R Resistor</div><div>1 x Male to Female Jump Wire 10pin</div><div>1 x 10K Potentiometer</div><div>1 x Passive Buzzer</div><div>1 x RGB Color Module</div><div>1 x Relay Module</div><div>1 x 9V Battery Button</div><div>1 x Active Buzzer</div><div>1 x 74HC595</div><div>1 x Infrared Receiver</div><div>1 x LM35dz</div><div>1 x Flame Sensor</div><div>2 x Ball Switch</div><div>3 x Photoresistor</div><div>4 x Button&nbsp;</div><div>4 x Button Cap</div><div>1 x Remote Control</div><div>1 x 4-Digit Digital Tube</div><div>1 x 8x8 Dot Matrix Module</div><div>1 x 1-Digit Display Tube</div><div>1 x Stepper Motor Driver Board</div><div>1 x Stepping Motor</div><div>1 x Servo SG90</div><div>1 x 1620 LCD</div><div>1 x XY Game Joystick Module</div><div>1 x Temperature Module</div><div>1 x Water Test Module</div><div>1 x Rfid522 Key Identification Card</div><div>1 x Sound Module</div><div>1 x Time Module</div><div>1 x 4x4 Key Board</div><div>1 x Pin Header</div>
