New feeds for UAV accessories :PPM encoder module,3DR Power Module,Optical flow sensor board


New feeds No.1: PPM encoder module


PPM encoder module is used to translates up to eight PWM (pulse width modulation) signals into one PPM (pulse position modulation) signal with ATMEGA328 IC, allowing you to connect a PWM receiver to a PPM-compatible autopilot with one wire, which on the one hand reduce the interface of the main chip and on the other hand save the space on PIXHAWK. As a result, you’ll get faster processing and reduced points of error.

New feeds No.2: 3DR Power Module


The 3DR Power Module is a simple way of providing your control board with data of the current consumption and voltage measurements of a LiPo battery so that the control board can estimate the remaining flight durations according to the remaining and power capacity and the real time current consumption calculated by the received data. This 3DR Power Module has the function of BES which can provide stable power supply to the control board.

• Max input voltage: 18V

• Min input voltage: 4.5 V

• Voltage and current measurement configured for 5V ADC

• 6-pos DF13 cable plugs directly to APM 2.5’s ‘PM’ connector

• Dimension: 23mm*22mm*10mm

• Net weight: 19.2g

New feeds No.3: Optical flow sensor board


This is the optical flow sensor board that is based on the optical effect of mouse sensor that allows you hover with your mulit-rotor platform at low altitudes (like indoor environment) without the need for GPS. This device also has more advanced features concerning odometry and obstacle avoidance.

  • Standard4.2mm IR MeGa lens 
  • High speed motion detection 
  • ADNS-3080 optical sensor
  • Up to 6400 fps update rate
  • 30×30 pixel resolution
