Sentry2 is a vision sensor which is designed by K210 - an advanced 64-bits RISC-V neural network processor. This device integrates a variety of advanced vision algorithms, which can meet the basic vision processing needs. The on-board ESP8285-WiFi chip can be programmed in for Arduino IDE to realize online-recognition, image transmission, AIoT and other applications. ESP8285 can be used as a controller for K210 which is help for AI programming without external controller. Applications: Robots, Smart Cars, Creative Design, STEAM Education, Maker, Toys, AIoT Sentry2 can be connected to a controller via the output port, or connect to computer by a USB cable. The output port can be set as UART mode or I2C mode, device address and baudrate can also be modified. Color: As Shown Material: Plastic+Metal Package Contents: 1 x Module
