Yup. Title. I’m gonna have to learn how to use confluence.

Communication with Jetson vs SPI/CAN/ETC/WHATEVER WE WANT

  • needs much more research.

  • need to confirm what data is being transferred. Is the camera module being handled by the jetson entirely? are we just getting position from cv? what’s the plan……

Some quick links

RTOS (zp) on Jetson?

CV on RTOS?

  • might have issues ← come back to this.

RPi vs Jetson

Below we find our comparisons between our different device considerations. These are the specs for the device module, not the developer kit.

Supported communication interfaces

GPIOs

Supports GPIO, I2C, I2S, SPI, UART

Supports UART, SPI, CAN, I2C, I2S, DMIC & DSPK, GPIOs

Supports GPIOs, I2C, I2S, SPI, CAN, and TTL UART with flow control

Cost

Starting from $35 (increases depending on RAM)

$149

$999

Starting at $299

Jetson TX2 NX is $199 but is smaller and has less RAM.

Notes:

Between RPI4 and Jetson Nano, RPI4 is slightly better in terms of Display and CPU. RPI also has built-in wifi (which is nice). The general computing performance between both devices is relatively similar; however, when it comes to machine learning, 3D graphics, or very complex algorithms, Jetson Nano is better thanks to its GPU.
