What did you personally accomplish this week on the project?
This week, I wanted to find a board that best suited our project. While Siena looked into raspberry pi boards, I looked into the Nvidia Jetson Orin Nano Super Developer Kit.
Below are the components of the board.
Price ($250)
I researched the basic setup that needs to be done when we get out board.
Hardware board setup: https://developer.nvidia.com/embedded/learn/get-started-jetson-orin-nano-devkit#intro
Software setup : Nvidia JetPack (software stack) – including Tesnsor RT, pytorch, etc
Choose to build project from source:
https://github.com/dusty-nv/jetson-inference/blob/master/docs/building-repo-2.md
After the steps above, pytorch will be installed, and either python or c++ can be used.
Below is a link to start coding our own image recognition program

For a live camera demo,
An MIPI CSI Camera can be used (port 9 of the board image above).
Raspberry Pi Camera Module 2 ($12)
AP-IMX290-MIPIYUVx1 – harder to buy
AP-IMX334-MIPIx1 – harder to buy
We can also use USB webcams (port 6 of our board image above).
Logitec C270($22)
Logitec C920($60)
For LCD, we can use
7 Inch IPS LCD Touch Screen Display ($46)
5 Inch IPS LCD Touch Screen Display ($40)
The one concern is that there aren’t many resources out there on LCD displays for Nvidia Jetson orin nano boards. I’m pretty sure the two displays above will work with the cable from DP-HDMI (jetson orin nano does not have an HDMI port, only a DP).
Another option is to use TFT LCDs and use the gpio pins on the board. This will be a cheap option for us, since the costs will be below $30, but the display will be small.
More research has to be done on how to communicate the output data to our LCD. Communication methods will vary based on the LCD we decide on.
Is your progress on schedule or behind?
My progress is pretty much on schedule, but I want to focus more on the LCD aspect next week. I want to decide which display our project will use (will it be connected via DP or GPIOs), and exactly how the software side should progress to deliver our output data to the display.
What deliverables do you hope to complete in the next week?
I hope to have chosen our board, and to have a plan on how the output data will be delivered to our LCD. I don’t think we’ll have our board by next week, but based on our board decision, I plan to look at the datasheets for hardware configuration of the LCD and research how the communication will work from the board to the display.
