Feature: 1. The circuit board already contains various components necessary for the operation of the control. You just need to connect to the computer via USB or AC-DC adapter, and the battery can be connected to the power socket to start the controller, making the operation more convenient. 2. The Due using 32-bit ARM core is more powerful than other development boards using 8-bit AVR core in the past. The 32-bit core can process 32-bit data in a single clock; CPU clock frequency of 84 MHz; 3. 96 KB for SRAM; 512 KB Flash; a DMA controller can reduce CPU strain during many calculations. 4. A microcontroller board based on SAM3X8ECPU. This is the first learning board based on a 32-bit ARM core. It has 54 digital ports 10 (12 of which can be used for PWM output), 12 analog car inputs, 4 UART hardware serial ports, clock frequency 84 MHz, one USB OTG interface, two DAC (analog (analog conversion -digital), two TWI, one power socket, one SPI interface, one JTAG interface, one reset button and one clear button. 5. Made of high quality ABS plastic material, hard, durable, corrosion resistant , long service life, more stable working performance and higher working efficiency. More in line with your needs, can bring you a better experience.
