In Axon lite
All internal thermal sensors are set as disabled

Is it because of some issues that you have done it intentionally?

If not can you please guide how to turn them on?

Axon Lite: tsadc node was kept disabled in the past kernel builds.
The latest kernel package exposes all the thermal zones properly at

To get the latest package, run the following commands

sudo apt update
sudo apt reinstall linux-image-6.1.75-axon-lite linux-headers-6.1.75-axon-lite

Or a simple apt update + upgrade will work fine if you are on an older build

Then perform a reboot to see your temps

Let me know if you face any issues.

Thank you

Also regarding the Supply in Axon lite

Are there any pads available to supply power to board other then C type supply?

You can use the battery connector for the purpose of direct DC supply, but DO NOT pump above 4.1-4.2 volts into it.

What if we want to power up board via 12 V DC SMPS

You can solder the 12V input here if you have the equipment
USB_DC_IN will be marked as “+” and GND as “-” on the actual board
