AT32-Video-EV board
Introduction
The AT32-Video-EV evaluation board is designed to achieve faster data acquisition and application
through video sensor, thus speeding up development cycles.
The evaluation board is built around a QVGA CMOS image sensor — BF3901 (BYD brand), and a
TM
2.4-inch TFT LCD touch display. Standard Arduino
Uno R3 connectors are intended for
connection to the ARTERY AT-START evaluation board or other compatible boards. Through
image processing control mechanism, the AT32-Video-EV board is aiming at driving various
applications such as QR code scanning, image recognition and gesture control.
