Overview:

- The UPixels optical-flow module(UP-FLOW) includes an optical-flow chip and a CMOS image sensor.

- The optical-flow module is used to detect the movement of a drone in the horizontal direction during flight, and the module transmits the result to the flight control. The flight control then combines with the altitude data to control the aircraft and achieve automatic hovering.

- This document describes the module's interface, size, and specifications related parameters, so that related personnel can develop based on this module.

Size and Structure:

- This product model is UP-FLOW-LC-302-3C, the hardware part is mainly the main board. As shown in Figure [ UP-FLOW-LC-302-3C size info. ]the schematic diagram of the main board size structure is as follows: Length 22 mm and Width 14 mm.

Functional Block:

- The optical flow module detects the horizontal moving distance of the aircraft in real time in a GPS-free environment, realizing high-precision positioning of the drone.

- The module obtains the image data through the COMS module and sends it to the optical flow chip. The chip uses the camera to capture the screen to get the displacement information of the drone, and then outputs it to the flight control through the UART interface, so as to control the horizontal movement distance of the aircraft and achieve the purpose of hovering.

- The structure of the optical flow module is shown in Figure [ Functional block diagram ].

Optical-flow Module Access Method:

- The optical-flow module connects to the flight controller via the UART interface. The UART data format is 1 start bit, 8 data bits, 1 stop bit, no parity bit, and the baud rate is 19200.

- The optical-flow module and flight control interface sequence is shown in Figure [ The optical-flow access interface ], where UART_ TXD, UART_ RXD is based on the optical-flow module, VCC is 3.0V-5.0V power supply input. The maximum power consumption is 90mW at 3.0V and 150mW at 5.0V.

Chip Overview:

- The UPixels optical flow chip U30-5A is an intelligent visual chip that detects the horizontal displacement of small micro air vehicles (such as quadcopter drones) in real-time through visual methods, used to achieve automatic fixed point hovering of small micro air vehicles.

- The UPixels optical flow chip first collects continuous image data from the image sensor as input, then detects the displacement of the continuous image sequence in the horizontal X and Y directions, and finally outputs the corresponding displacement detection results. Figure [ U30-5A Chip System Framework ] depicts the framework of the UPixels optical flow chip system.

Optical-flow Module Initialization and Data Definition:

- After the optical-flow module is powered on, it will be initialized by itself. At least 100 ms delay is required between powering up the optical-flow module and the initialization.

Note:

- Size is manual measurement, there are exist errors.

- The connecting wire will not include.
