Iduino Due 2013 R3 3D Printer Motherboard Main Controller Panel ARM 32bit Master Plate Compatible with Arduino

The advantage of ARM core:
Using 32-bit ARM core Due, compared with the use of past eight AVR core of other Iduino more powerful.
 
Main differences:
- Core in a 32-bit clock can handle 32-bit data
- CPU clock frequency of 84 MHZ
- 96 KBytes of SRAM
- 512 KBytes of Flash
- A DMA controller, which can reduce the CPU to do a lot of stress of operation
 
Technical specifications:
- AT91SAM3X8E controller
- The working voltage of 3.3 V
- 7-12 v input voltage (recommended)
- The input voltage (limit) 6 to 20 v
- Digital I/O pins 54 (one of 12 PWM outputs)
- The analog input Pins 12
- Analog output Pins 2 (DAC)
- IO mouth total output current 130 mA
- 3.3 V port output capacity of 800 mA
- 5 v port output capacity of 800 mA
- 512 KB Flash (all space can store the user program)
- 96 KB SRAM (two parts: a 64 KB and 32 KB)
- 84 MHz clock rate
 
 
The storage space:
SAM3X 512 KB (256 KB) two pieces of Flash storage space used to store the user program.ATMEL chip in production, has reduced the bootloader presintering written into the ROM.There are 96 KB SRAM, made up of two contiguous space of 64 KB and 32 KB. All the available storage space (Flash, RAM and ROM) can directly address.Wipe button, you can use the board erasing SAM3X data in a Flash.This operation will delete the current load.Under current condition, hold the wipe button for a few seconds, then wipe.
 
The input and output:
- Digital I/O: pins from 0 to 53
- Using pinMode (), digitalWrite (), anddigitalRead () function, every I/o can be used as input and output ports.They work in 3.3 V.Every IO can output 3 15 mA mA or current, or input 6 9 mA mA or current.They also have 100 k the internal pull-up resistor (not on by default).In addition, some pins have special features:
- Serial: 0 (RX) and 1 (TX)
- Serial 1:19 (RX) and 18 (TX)
- Serial 2:17 (RX) and 16 (TX)
- Serial no. 3:15 (RX) and 14 (TX)
- PWM: pins 2 to 13 use analogWrite () function provides eight PWM output. By analogWriteResolution () function changes the PWM output precision.
- SPI: SPI interface (called on other arduino ICSP interface) can be used through the SPI library is SPI interface to communicate.Has led to the SPI pin 6 pin interface position, can and Uno, Leonardo, Mega2560 compatible. The SPI needle is used only for and other SPI communication equipment, cannot be used for burning SAM3X programs.Due to the SPI can be Due to the expansion of the special library to use the advanced features.
- CAN: CANTX and CANRX hardware CAN support, but the Arduino IDE doesn't provide the API
- TWI 1:20 (SDA) and 21 (SCL)
- TWI 2: SDA1 and SCL1. Support the use of Wire TWI communication library
- Analog input: A0 to A11 Iduino Due to there are 12 road analog input, each all the way there are 12 precision (0-4095).By default, the analog input accuracy of 10, and other types of Arduino controller.Through analogReadResolution () you can change the ADC sampling accuracy. Due to the analog inputs pin measurement range of 0 to 3.3 V.If the measurement is higher than 3.3 V voltage, may burn out SAM3X.AnalogReference () function on the Due is invalid.
- AREF pin through a resistor bridge received SAM3X simulation reference. If you want to use AREF feet, you need to be removed from the PCB BR1 this resistance.
- DAC1 and DAC2 through analogWrite () function provides 12 precision analog output (4096 rating). You can create Audio output through Audio library.
