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
