i'm working on a USV using the corewing f405 wing v2 but there is no supported ardurover firmware for it, i've tried using the matek f405's firmware and speedybee's but both have problems either with the IMU (speedybee) or the barometer (matek) does anyone have experience with this board? will i be able to run ardurover on it or should i just buy another one?
matek firmware:

i know the board is not defective or anything since i was able to run inav firmware on it and make an rc car out of it, today ill probably try to do waypoint missions with it since it has gps.

heres my entire components list:
Flight controller stack

• CoreWing F405 WING V2 (flight controller board, top plate, and PDB PLUS, running as a set)
• CoreWing Wireless USB Extender PRO (came with the stack, not yet used for telemetry)

Receiver and RC link

• Radiolink R6FG receiver (individual PWM outputs per channel)
• ESP32-WROOM-32 DevKitC clone, with a CP2102 USB-to-UART chip, used as a PWM-to-SBUS bridge

GPS and compass

• Walksnail WS-M181 (GPS over UART, compass over I2C)

Firmware and tools

• INAV Configurator, current firmware setup for the rover
• Arduino IDE, for the ESP32 sketch
• SBUS library by Bolder Flight Systems, for the ESP32's SBUS output

second post i deleted the first one, this one is after more research
project requirements:
gps waypoint guidance
telemetry
flight controller below or around 50 euros, the whole fc+ sensors needs to be below 100
ovverride using a r6fg reciever
i already know about the power side except the power needed for the "brains" of the boat, my esc has a 5v bec integrated tho.

do i go for an f405?

I started learning about ardupilot today, thos project probably is going to use ardurover since its a boat

I want to build a basic unmanned boat, the design of the boat doesnt matter much for now

Budget is strict, keep it around 100€ max, if possible 50€ (budget is only for the flight controller part as i already have all of the other stuff)

Requirements:

Gps waypoint following

Telemetry

Override with something like an rg6gs remote (since i have it already)

What flight controller do you guys suggest?

Do i buy a vhf antenna for walkie talkies? 16 euros, light, 2dbi, <2 vswr male sma so straight onto the rtl sdr

Or a cheap standard marine band antenna? 40 euros, 2.5dbi, <1.5 vswr with a pl259 and cable so needs an adapter

I'm gonna get a nanoVFA in a month so the antenna should be a cheap portable stopgap solution since ill be able to just build my own antennas
