Microduino-Core

Microduino-Core is one of core modules of Microduino series, Microduino-Core is an open source hardware and Arduino Uno compatible. It is an 8-bit microcontroller development board, based on Atmel ATmega328P/ATmega168PA series.

Comparing to Arduino Uno, Microduino-Core is featured by:

  • Microduino splits Arduino Uno into two parts: Microduino-Core and Microduino-FT232R modules -- MCU and USB2TTL parts. it means once designers uploaded program into Microduino-Core, Microduino-FT232R will be not necessary anymore, designers could have many Microduino-Core/Core+ modules with only one Microduino-FT232R. The board size becomes very small as only 25.4mm X 27.94mm (1.0inch X 1.1inch), like a quarter.
  • Microduino series uses the U-Shape 27-pin interface (UPin-27), the standard interface of Microduino, all Microduino modules and sensors can be easily stacked and extended, it is delivered ready to plug in.
  • With tiny shape and uniform interface, Microduino series dramatically decreases the size and cost of design prototype, remarkable improves usability and flexibility of Arduino-compatible boards, as well as user experience.

Microduino uses the same development environment as Arduino IDE, designers can use the Arduino IDE, Processing on Microduino for idea realization, prototype development and low volume production.

Microduino uses optiboot for bootloader, it takes less Flash than Arduino default engine and optimizes program uploading.

Currently, there are 4 different configurations for Microduino-Core modules:

Type Flash SRAM EEPROM Frequency Supply
Atmega328P@16M，5V 32K 2K 1K 16M 5.0V
ATmega328P@8M，3V3 32K 2K 1K 8M 3.3V
ATmega168PA@16M，5V 16K 1K 512 16M 5.0V
ATmega168PA@8M，3V3 16K 1K 512 8M 3.3V

Different configurations in frequency and supply voltage:

  • Clock frequency and supply voltage are paired, 8M module is supplied by 3.3V voltage, while 16M module is by 5.0V voltage.
  • A 16M with 5V Microduino-Core module is recommended for desktop equipments or designs; regarding mobile equipments or designs, a 8M with 3.3V module is suggested for low power and battery supply purposes.


Core vs Core+

  • Microduino also provides Microduino-Core+ module, aiming at high performance applications which require large SRAM/EEPROM/Flash and more I/O ports.
  • Both Microduino-Core and Microduino-Core+ use UPin-27 interface -- the standard module interface of Microduino series. The main difference between them is MCU chip: -Core module uses ATmega328P/ATmega168PA, as same as Arduino Uno; -Core+ module uses ATmega644PA/ATmega1284P, its performance is similar to Arduino Mega2560.
Microduino Chip Flash SRAM EEPROM Digital I/O Analog I/O PWM Hardware Serial
Core Atmega168PA 16K 1K 512 23 8 6 1
ATmega328P 32K 2K 1K 23 8 6 1
Core+ Atmega644PA 64K 4K 2K 32 8 6 2
ATmega1284P 128K 16K 4K 32 8 6 2
  • According above table, Core and Core+ are different in Flash, EEPROM and SRAM size, also, they supply different size of digital I/O and hardware serial ports, and there are 10 more digital I/O and 1 more hardware serial ports in Core+. Designers can select specific module regarding different application requirements on function, performance and power.
  • Both Core and Core+ use UPin-27 interface, Microduino program can be smoothly ported between them.
