+
* Digital I/O There are 32 number digital input/output:
−
* 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-Core+]]''' aims at high performance applications which require large SRAM/EEPROM/Flash and more I/O ports, '''[[Microduino-Core]]''' is for main stream applications.
 
−
 
 
−
* 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-Core+

Microduino-Core+ is an 8-bit microcontroller development core board based on Atmel ATmega1284P and ATmega644PA series as the core and it is an open-source controller module compatible with Arduino UNO. Beside Microduino-core+ has the features of Microduino-Core, the number of input and output of Flash, RAM, EEPROM of it has been greatly improved, and the pin conforms to the norms of Microduino, and the players can upgrade core to core+ smoothly, without modifying the arduino code basically.

  • Open source hardware circuit design, and compatible-with Arduino programming development environment;
  • Same with Arduino, Microduino can use ISP download line to program to 「bootloader」 flexibly;
  • The unified Microduino interface specification and abundant peripheral modules can be connected and extended with other modules and sensors conformed to the Microduino interface specification conveniently and flexibly;
  • 2.54 spacing mother of interface is convenient to integrate into the hole plate.

Specification


  • Microduino-Core+According to the different core and clock frequency, there are four different versions at present:
MCU type Flash SRAM EEPROM Clock frequency Work voltage
ATmega644PA 64K 4K 2K 16M 5.0V
ATmega644PA 64K 4K 2K 8M 3.3V
Atmega1284P 128K 16K 4K 16M 5.0V
ATmega1284P 128K 16K 4K 8M 3.3V


  • Digital I/O There are 32 number digital input/output:
    • Labeled on the module of D0, D1, D2~D13 and A0~A7, and the 10 （D14~D23） more than core .
  • Analog I/O There are 8 analog input/output:
    • Labeled on the module of A0~A7;
    • Each provides a 10-bit resolution（that is 0~1024）. By default, analog value measurement range is from GND to VCC voltage value;
    • Please refer to analogRead() function.
  • There are 8 PWM supports:
    • Labeled on the module of respectively D7,D8,D9,D10,D12,D13,D22,D23.
    • Please refer to analogWrite() function.
  • There are two serial port supports:
    • Labeled on the module of Serial[D0(RX),D1(TX)] and Serial1[D2(RX),D3(TX)].
    • Connected with USBTTL,it will occupy D0 and D1. If the ports D0 and D1 are also occupied by other modules, this will lead to the communication with USBTTL is abnormal and the program can not be downloaded.
  • There is one SPI support:
    • Labeled on the module of D13(SCK),D12(MISO),D11(MOSI) and D10(SS).
  • There is one 12C support:
    • Labeled on the module of SDA(D20),SCL(D21).
  • There are 3 external interrupt supports:
    • Labeled on the module of D2(interrupt0),D3(interrupt1) and D6(interrupt2).
    • Please refer toattachInterrupt()function.
  • Support the ISP download function.
  • Support the AREF end.

FAQ

  • Q:How do I judge that the voltage of the Core+ is 3.3V or 5V?
    • A:Look at the resistor. If the R1 is welded, it is 3.3V. And if the R2 is welded, it is 5V.
  • Q:Can I use 3.3V voltage to supply power to the Core+ of 16m clock frequency?
    • A:It is not recommended . If the voltage is too low, it is easy to be unstable.
  • Q:Can I use 5V voltage to supply power to the Core+ of 8M clock frequency？
    • A:Yes, you can.
