Hi,
I'm working on a thermal imaging camera project using an AMG8833 and was just wondering if a 0.96" OLED display would be too small to display the temperature readings. This is my first project with an Arduino so I'm a bit nervous when comes to using certain components, I.e not wanting to use a larger display that requires 5V as my Arduino Uno REV3 only has one 5V pin and thats for the AMG8833.
Any help is appreciated, thanks!
...which has a supply voltage of 3 to 3.6V.
Are you wanting to display all 64 temperature values?
If so, a 0.96" display is not the way to go
Post a link to the AMG8833 module you have. Some have a voltage regulator and logic level shifters for use with 5V Arduinos.
my Arduino Uno REV3 only has one 5V pin
That can be used to power more than one small device, but you must obey the manufacturer's advice on current draw (less than 100 mA is probably OK).
So I should be able to use my 3.3v pin to power the AMG8833? Every YouTube video and other forum I've been to and asked on just states to use the 5V pin to power it however I'm assuming they didn't know I wanted to use a display. In theory I should be able to use any 5V display now? I only queried about a 0.96" as its cheap and can operate at 3.3, with a larger size I can comfortably fit all 64 on?
Hi,
I was following this guide https://projecthub.arduino.cc/jdanielse/1dfb5ad8-555f-476f-bb9f-4ec3dee95bd1 firstly on it, in which he states that it can be used 3-5V
Please post a link to the product page for the AMG8833 module you have.

That sensor is for 3.3V logic (I/O) connections only.
You will need logic level shifters to connect that to a 5V Arduino. Not advisable.
Do you have any other recommendations of AMG8833 that i'd be able to use then? Or do you just mean this one in general?
That was another solution, however as its a project for college, I was trying to keep costing low. Do you have full link to your project anywhere? I'd love to see how you have done it!
I do not have a full link to my project.
I use 2 AMG's, an ESP32, and a machine learning algorithm (KNN) to detect small, medium, and large animals and trigger events based upon animal size.
I used wires and solder and protoboard to make my project.
The Adafruit AMG8833 module has logic level shifters built in and can be used with either 3.3V or 5V processors.
But it would be cheaper to buy a 3.3V Arduino board, which you can connect directly to any 3.3V sensor or display.
5V logic will soon be a thing of the past, so it is time to move on.
