Microduino-CoreUSB

Microduino-CoreUSB 8-bit microcontroller development board with the ATMEGA32U4 series as the core,and it is a open-source controller module compatible with Arduino Leonardo.

The difference between Microduino-CoreUSB and Microduino-core and Microduino-core+ is that the Microduino-CoreUSB contains a microcontroller and USB communication, equivalent to （Microduino-core + Microduino-USBTTL）, and its pins conform to the microduino specification. Microduino uses java , the development environment of C language, same with Arduino. Players can use Arduino IDE, cooperating with software such as Flash or Processing , with Microduino and other electronic components,modules and sensors to make many funny interactive works.

Features

• It contains microcontroller and USB communication, so you can directly download programs through the USB port, having no more need of Microduino-USBTTL；
• USB overcurrent protection；
• Small, cheap, stackable, and open；
• Open-source hardware circuit design, and programming development environment compatible with Arduino ；
• Same with Arduino, Microduino can use ISP download way, to program to「bootloader」 flexibly；
• Unified Microduino interface specification, and abundant peripheral modules, can be connected and extended quickly, conveniently, and flexibly with other modules and sensors conforming to the Microduino interface specification；
• 2.54 spacing Female Header interface is convenient to integrate into the hole plate.

Specification

• Digital I/O There are 22 digital input/output terminals：
  • Labeled on the module of D0~D13, and A0~A7.
• Analog I/O There are 10 analog input/output：
  • Labeled on thee module of A0,A1,A2,A3,A6,A7,D8(A8),D9(A9),D3(A10) and D4(A11)；
  • Each offers a 10-bit resolution（ that is 0~1024）. By default, the measurement range of the analog voltage is the value from GND to VCC；
  • Please refer toanalogRead() function.
• PWM support. There are 8：
  • Labeled on the module of respectively SCL,D3,D4,D5,D6,D7,D8 and D9.
  • Please refer toanalogWrite() function.
• Serial port support. There are 2：
  • USB virtual serial port Serial；
  • Labeled on the module of Serial1[D0(RX),D1(TX)]。
• SPI support. There is one：
  • Labeled on the module of D13(SCK),D12(MISO),D11(MOSI),D10(SS).
• I2C support. There is one：
  • Labeled on the module of SDA(D18),SCL(D19).
• External interrupt support. There are 5：
  • Labeled on the module of SCL(interrupt0), SDA(interrupt1), D0(interrupt2), D1(interrupt3), and D2(interrupt4).
  • Please refer toattachInterrupt() function.
• Support the ISP download function.
• Support AREF end.

Development

• 1.Downloading programs to Microduino-CoreUSB , players need to use Microduino-USBTTL module.
• 2.The tutorial of setting the development environment and installing the driver is as following：
  • Microduino Getting start

• Program Microduino BootLoader
  • If BootLoader is damaged, you need to use Arduino UNO or existing Microduino to program bootloader to the damaged Microduino ；
  • Players can refer to： Do you know how to use Arduino UNO to program bootloader to Microduino-Core？.。
