BetaFPV Pavo Pico modification | DJI O3 Lite | M10 GPS | FPV Drone | Sub 100g FPV

The Pico patch 2 has a spared UART, why don't we add a GPS on it as suggested officially?
But I have already installed crossfire nano, the total weight with 500mAH lipo is already 100g, is it possible to maintain its weight not more than 100g?
Of course, Flywoo has a O3 lite kids to trim down its weight. However, after several trials, I still feel not very comfortable with the ways to anchor the lite O3 to the Pico cage.
The goal is just to reduce 8g from the total weight. After calculation, it can be done by simply removing the top and bottom of the O3 case. We can use the O3 original antenna and coaxial cable lockers as well.
It is still not enough! Well, we can go further by trimming the camera. As I don't want to buy a new set of ND filters, I decide just to remove the back cover of the camera, so that I can keep using the flywoo ND filters.
Bingo! 100g

Hi how did you add the gps module? is there a build video?

Ótimo vídeo Piloto...

嘩！ sub100g with GPS! 咁呢部雞仔可以飛盡DD 都唔驚唔見了。有無多D實測片

都係, 不過安唔到BUZZER, 炒咗都係有排搵

Hi, with your settings, PP flies super stabe for cinematic filming. Can you share your PIT values, pls.?

[@spacemonkey986]

dont you think it would have been helpful showing where the GPS wired to the board?

[@MrEmn3sty]

Good video!! How did you attach the antennas on the frame??

[@PipaMima]

Hello, which uart you use for gps?

Nice. Fun overview and flight. What is your goal with the GPS unit? I want to add a ViFly Finder Mini to my Mobula8, but hadn't really considered adding a GPS to it.

[@dsjay]

I agree with you Finder is very useful if we lost the quard in bushes. I crashed it and it was almost unable to retrieve it with no buzzer. Although the we can set channel to produce sound by the motors, the volume is so low for such a small motors that I can say it is not suppose to use in that way.
Adding GPS just in case if fail-safe happened, like the video linked below. Now the signal acquire ability was improved much by M10, if there is a spared UART, it is worth to add it.

Thanks for sharing, how much flight time and did you set up and test gps for 'return to home'?

[@dsjay]

I used the 500mAh HV lipo as shown in the video, it can provide a 3-4 mins cruise flight. But if under strong winds, only 2-3 mins MAX. I have not tried the "return home" yet, but the satellite signal could maintain 8 satellites or above during flight.

[@momowong]

Are u using Betafpv AIO FC? I hv a pavo20 with TBS receiver, but the Betafpv controller has not enough UART support for both external receiver and GPS.

[@dsjay]

Yes, this is BetaFPV AIO FC, but they call it batch 2, which is 20A with a spared UART. The first batch FC was 12A only and with just 1 spared UART excluding the one for VTX.
