RE the substantial heatsink that is a feature of the “Alta”, I was wondering whether you might be able to tell me if I can safely and easily remove it?
I ask because I want to use the Alta as a drop-in replacement for a Raspberry Pi 3B+ in a pi-top [3] laptop shell.
Whilst I have been able to fit the Alta inside the shell, in order to be able to use it I need to connect the cooling bridge from the Alta’s GPIO pins to the B2B connector on the shell’s Hub.
Due to the way the cooling bridge is shaped, I can’t do this without removing the Alta’s heatsink.
Normally I wouldn’t worry too much about removing a heatsink but normally that’s because I’ve installed the heatsink myself. I received the Alta as a present and am just a little apprehensive about removing the heatsink without Libre Computer’s guidance.
I would really appreciate your support in this matter and look forward to hearing from you soon.
The heatsink can be removed.

Thank you for your quick response.
I should have been more specific because what I’m really seeking advice on is:
Can the heatsink be easily removed by hand* without any risk of de-lidding the CPU/RAM, or causing damage to the PCB?
*in the same way I would remove a heatsink I’d applied myself with thermal pads to a Raspberry Pi 3B+, for example
Yes, you should be able to remove it without damaging anything.

Great - thank you very much for your help!
@librecomputer is there a hardware enablement table showing mainline kernel status for the A311D, like the one Collabora has for the RK3588?
Looking at another thread, I’m trying to understand if there’s anything I need to do to connect a PWM Servo Board using I2C to the Alta board.
When I used Le-Potato, I did have to enable i2c-1 interface, and that was pretty straight forward. but that is not the case with the Alta board.
I know I’m not an electronics expert, so am asking for some help/guidance to advance my project (autonomous RC car)
Thanks!

Hello, Could I please have some clarification:
I’ve received an Alta labelled AML-A311D-CC-V1.0C
Documentation and files available reference:
V1, V01-preprod and V02-preprod
Which of the three boards does V1.0C correspond to, or is this a fourth, yet undocumented board variant? I don’t want to accidentally flash the wrong firmware image.
V1.0C means V1 with Type-C
Revisions are minor increments, eg V1.1C
Minor versions have no software changes.

Oh thank you for that! I’d missed your reply but that’s a really useful resource to have!
