If you don’t know what to choose between the raspberry pi 4 and the jetson nano it is something very normal in order to control, give some commands to a drone my friends and personally used the raspberry pi 4.
This is what happened first we bought the jetson and gave up on it and bought the raspberry pi 4 both of them are different but they can be used for the same purpose. For applications like image classification, object identification, segmentation, and audio processing, this powerful computer allows you to run many neural networks simultaneously.
Raspberry pi 4 Vs Jetson Nano (4GB)
The jetson nano is more expensive than the raspberry pi 4, the hardware in terms of the CPU the raspberry pi 4 Quad-core A72 CPU at 1.5 GHz and the jetson nano Quad-core A57 CPU at 1.43 GHz got a slightly lower CPU than the raspberry pi 4, in terms of memory both of them got 4GB DDR4 RAM,
in terms of GPU the raspberry pi 4 has got a video core VI (GPU: Broadcom) and the jetson nano has got a GPU of 128 CUDA core Maxwell the big difference in both of them there a multiple GPU on jetson nano both of them support 4k in terms of display in the raspberry pi 4, there is 2x micro HDMI Up to 4k,60fps and the jetson nano has 1x HDMI& 1XDP Up to 4k,60fps both of the ports offer H.264 & H.265 hardware decoding up to 4k at up 60fps with the right software both of the devices use a microSD card as storage.
In terms of networking the raspberry pie use Gigabit Ethernet & Wifi & BT 5.0 and the jetson nano Gigabit Ethernet(& E-keyed M.2).In terms of port, the raspberry pi 4,2x USB 2.0 & 2X USB 3.0 and a MIPI CSİ &DSİ Connector and the jetson nano 4x USB 3.0 and MIPI CSI both have a header that allows having power over the internet. When it is coming about the power the raspberry pi 4 is connected with a USB-C power with 5 volt
and the jetson nano is connected with the Micro USB or the barrel jack.
The jetson nano offers a more significant upgrade over the raspberry pi 4.

I wouldn’t say that the Jetson Nano is an upgrade over the Raspberry Pi 4, as the Cortex-A72 CPU of the Pi 4 is actually an upgrade over the Cortex-A57 of the Jetson Nano (see https://en.wikipedia.org/wiki/ARM_Cortex-A72). Also, if it is a drone you want to make: the Jetson Nano is more heavy than the Pi 4 and needs more cooling. The GPU of the Jetson Nano is way better, but you might perhaps want to have a Raspberry Compute Module 4 (CM4), connected to a camera in a drone that sends its data to the Jetson Nano on the ground to be processed -or a Jetson Xavier or Orin for that sake.
We had cooling issues with the Jetson Nano and the Pi 4 is lighter, we also wanted the drone to be under 5kg.
