【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..
Yahboom Single Board Computer K210 Developer Kit with AI Vision RISC-V Face Recognition Camera Touch Screen Programmable Development Board (Complete Kit) (K210)
K210 developer kit adopts RISC-V processing architecture, a mini full-featured development board kit designed for machine vision and auditory multi-modal recognition. It can be widely used in smart homes, smart robots, security monitoring and other fields.
Board comes with HD camera, capacitive touch screen, on-board indexing electronic components, such as three-way switches, RGB lights, gyroscopes, speakers, ESF8285-WIFI module, microphone array interface, etc. In addition, all IO ports of the K210 chip are led out through the pin header, which is convenient for users to expand..
Supports 3 development environments of Windows/Linux/Mac OS. When the computer and the K210 development board are connected to the same WiFi, they can communicate with each other, that is, combined with IOT to achieve remote control.
The development board comes with a factory test program, but the demo program needs to be burned in by yourself. Yahboom provides a large number of open source courses and materials, and supports online after-sales technical services..
