【Same function as the original Arduino】It great for learning the basics of how sensors and actuators work, and an essential tool for your rapid prototyping needs
【CHIP UPGRADE】Upgrade the main control chip to ATMEGA328P-AU.And it same as the original arduino pin layout. It compatible with all expansion boards.
【ADDED A 500MA SELF-RECOVERYFUSE】Compared with the original ARDUINO, a 500ma self-recovery fuse is added, which automatically disconnects the circuit when short-circuited to avoid component damage.Change the plug-in pins of the original ARDUINO to SMD pins to avoid short circuit of the development board contact conductors, which is safer.
【Added 10 LED marquees driven by MOS tubes】which avoids the problem of insufficient output current of the IO port of the single-chip microcomputer, and can directly drive a small DC motor through the IO port.
【EASY TO USE】Change the original USB-B type interface to MICRO-USB interface, which is more convenient to use.
