PX4FLOW – Smart Camera QUICK START – HARDWARE VERSION 1.3 Features Description PX4Flow is an optical flow smart camera. It has a native resolution of 752×480 pixels and calculates optical flow on a 4x binned and cropped area at 250 Hz (bright, outdoors), giving it a very high light sensitivy. Unlike many mouse sensors, it also works indoors and in low outdoor light conditions without the need for an illumination LED at 120 Hz (dark, indoors). It can be freely reprogrammed to do any other basic, efficient lowlevel computer vision task. 168 MHz Cortex M4F CPU (128 + 64 KB RAM) 752x480 MT9V034 image sensor ●L3GD20 3D Gyro ●16mm M12 lens (IR block filter) ●Size 45.5 mm X 35 mm ●Power consumption 115mA / 5V ● ● http://pixhawk.ethz.ch/px4/ Connectors and Dimensions Status Leds Green: ON Red: ERROR Ø 3.1 mm (M3) Amber: COMMUNICATION Blue: ACTIVITY Reset Switch RST z y x Lens Mount 16mm M12 (S-mount) USB I2C1 Ø 2.1 mm (M2) 9.1 mm 4 1 1 6 USART3 22 mm 30.4 mm PX4FLOW v1.3 35 mm 16.7 mm JTAG USART2 6 24 mm 45.5 mm 1 Pinout and absolute maximum Ratings ● UART3 1 1 Mates 6 pos Hirose DF13 housings Part # DF13-6S-1.25C Crimp terminals Part # DF13-2630SCF (for AWG 26-30 wire) 6 UART2 1 Mates 4 pos Hirose DF13 housings Part # DF13-4S-1.25C Crimp terminals Part # DF13-2630SCF (for AWG 26-30 wire) GND USART3_CTS USART3_RTS USART3_TX USART3_RX VDD_5V 6 Output: 3.3 V (VDD_3V3), 500 mA GND USART2_RTS USART2_CTS USART2_RX USART2_TX VDD_5V I2C1 GND I2C1_SDA I2C1_SCL VDD_5V 4 ● Input: 4.3-6 V (VDD_5V), 115mA onboard use, max. 800 mA for peripherial load Mates 6 pos Hirose DF13 housings Part # DF13-6S-1.25C Crimp terminals Part # DF13-2630SCF (for AWG 26-30 wire) Assembly Instructions 1 USART2 6 ● PX4FLOW acts as a slave and is connected to a host device e.g. autopilot board using the USART3 port.
