    No. Just get Here+ documentation and really just use UART to decode the information being sent by the GPS module

    Try HobbyKing. I buy most of the stuff from there.

    for a combination that could house and lift RPi? No. This battery wouldnt be able to provide the required power hence your copter wouldnt take-off.

    I prefer buying stuff from UAV related products from HobbyKing (https://hobbyking.com).

    Solar panel to fly a DJI phantom sized UAV would weight roughly around 50-70kg! Solar cells do not deliver much current, therefore, no you cannot make a a solar power quadcopter as of now.

    Also, LiPo is recommended as it provides the required Power-Density and Energy-Density requirements. (Images source: https://www.gelest.com/applications/batteries/)

    No! SBC and Microcontroller work on 3.3V/5V/6V/12V which is a standard with electronics domain. SBC and microcontroller are low powered items (5V-3A compared to 11.1V-30A motor) and cannot dictate the overall voltage of your system. Usually SBC and microcontroller are already fitted with in-built voltage regulators.Also if you haven't noticed, RPi and Pixhawk requires 5V/6V while I recommended the use of 3S LiPo battery (11.1V/14.8V).Usually your ESC (unless its OPTO) has voltage regulator built in. What it does is, it takes input from the battery, and outputs 5V/6V from the servo connector. This output is used to power the SBC and flight controller.If your SBC doesn't support 5V/6V then you can always buy a suitable BEC (Battery Eliminator Circuit) to match the output requirement. Motors…

Motors are the key element that consumes the most power and dictates the required voltage of the system. You need to make sure you match the manufacturer's requirement otherwise your SBC and flight controller would be working fine, but your vehicle would either burn its motor or wouldnt take off

    TELEM port has a power limit. I used to power RPi but takeoff and sudden maneuvers would restart RPi. I recommend using a BEC to be plugged in to servo rail and powering you RPi through the rail (BEC). By the way, LiDAR doesnt take much power compared to RPi (almost negligible)

    Hello! Thanks for the appreciation. You can find the application at Benewake's website as well, just Google it, hopefully you'll find it

    Hello Qazi, Thanks for reading my post. I am very much aware that those hex code is not at all necessary. If you had a chance to research the product, you'll must have come across that there are two commands "42 57 02 00 00 00 04 06" and "42 57 02 00 00 00 01 06" for decimal and hexadecimal formatted output (change being in the 3rd last number). I initialize this so we all get same output and our code "works properly". Also, the code was tested numerous times before posting. Please consider the fact that this post was written back in Jan 2018 (approx 2 years ago). I bet there's a mismatched/missing library issue, I'd love to help you regarding this issue if you can be specific about the warning/error that you're getting (could be hardware or software as well…

  • (Update) Hey KalpeshB4! I was facing the sameissue earlier today, turns out I had a loose connection. I cut the wire and thejumper and soldered it, and now it's working perfectly fine.

  • Correction: LiDAR can sense from 30cm to 1200cm (12m). Are you using the same model?

    I am not sure about the environment you're using to test your LiDAR. LiDAR can sense up to 12m (12000 cm). In outdoor conditions the value can lie between 30cm to 7000cm
