Mini remote, a retrospect.

Thanks for the images.
On the first glance, the so called ‘‘reliable green pcb’s’’ have design date of 2020 while the yellow ones are older 2011 design. Interesting… Are there any marking on the main chip (longest one in the middle) of the green pcb?

Bumping this topic.
I replaced my remote with unfancy one and all the cutout problems are gone. However I will try doing some RF experiments in spring with mini remote on hand and some DIY diagnostics tool.
Still looking for pictures of green pcb mini remotes. I am mostly interested in chips used and layout so if you have such remote even serial numbers no chips are good enough.
