Features: 1The circuit board already contains various components required for control operation. You only need to connect to the computer via USB or through an AC?DC adapter, and the battery can be connected to the power socket to start the controller, which makes the operation more convenient. 2The 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 one clock CPU clock frequency of 84Mhz 396KBytes for SRAM 512KBytes of Flash a DMA controller can reduce the pressure of the CPU when doing a lot of calculations. 4A microcontroller board based on SAM3X8ECPU. It is the first learning board based on 32?bit ARM core. It has 54 digital 10 ports (12 of which can be used for PWM output), 12 analog car entrances, 4 UART hardware serial port, 84MHz clock frequency, one USB OTG interface, two DACs (analog (analog?to?digital conversion), two TWI, one power socket, one SPI interface, one JTAG interface, one reset button and one erase button . 5Made 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.
