@@vnagaravi Actually It was success in the second attempt. In the first attempt I ripped a one pad due to not having enough flux. Having the lesson learned, second time I was very carefull and it works!! /dev/mmcblk0p2 115G 1.9G 107G 2% /
i too realized too late that 8GB is an awfully low amount of memory and SD cards dont work. they dont tell you that when your buying them. also how do they produce more CM4 boards when these emmc modules are obsolete? the scalper market fd the real consumers hard here. you have to go through china's resale market to get one.
Even if these specific ones are obsolete, you can probably just grab any module and size you like, as long as the BGA pin layout is the same. As for how they can still produce new CM4 boards: It's all a matter of having the right contracts. The RPi Foundation is not buying at resellers like we do, they have direct agreements with the manufacturers.
Nice! I had found those too, but didn’t get one because they were more than twice as expensive as the 128 GB ICs - and those were not exactly cheap already. 😅 My hot air station doesn’t calibrate very well. I set it to 480 °C, but that is probably more like 440 or 450 on more accurate stations. Air speed was 70 or 75 (of 200) from what I remember.
