Language:	English  • 中文

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 Flash 32 KB（ATMEGA32U4）. 4 KB during it is used to guide the program. SRAM 2.5 KB（ATMEGA32U4） EEPROM 1 KB（ATMEGA32U4） Clock speed 16 MHz 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.
