AR1820 18MP Color Rolling Shutter Camera for Raspberry Pi

Introduction

Arducam AR1820HS camera breakout incorporates ON Semiconductor 1/2.3−inch CMOS active−pixel digital imaging sensor AR1820HS with 1.25um x 1.25um A-PixHS™ BSI Pixel . It can support 18-megapixel (4912H x 3684V) digital still images at 24 fps and a 1080p plus additional 27 percent pixels for electronic image stabilization (2448H x 1378V) in digital video mode at 60 fps and 1080p120 fps.

Arducam developed a special camera driver for Raspberry Pi, which lets you can capture 18MP still image and 1080p video on your existing Pi board.
