No, it's field-programmable. But you can only do it once.

Hehe, I was also tricked into thinking it's an 8051-compatible :-)

Today we are used to luxury of fully integrated microcontrollers - all key components are conveniently integrated into single reliable part: non-volatile memory, SRAM, CPU core, PLL, ADC/DAC, PWM, serial ports, e.t.c It was not like th

USB hub chip, USB<>SATA adapter - eating power for sure... SoC voltage scaling - need to be checked.

I was originally from Belarus, but as you mention - I am indeed in Zürich for some years. Still, I can assure you, 99% of people in Belarus do work on x86, and cutting edge x86 hardware is being sold freely. Technological sanctions failed m

It's just a step. We are not there yet. But we have to continue one step at a time.

Nearly all Linux packages you might want to install - work with nothing special required. Migration to ARM earlier this century made vast majority of open source software portable. Precompiled x86-only surely will not work.

USB 3.0 can eat alot of power due to high speed, if it's always active...

Do you imply that chip is fake and does not work? :-) Do you imply that there are no fake products on Amazon, which is also making chips (AWS Graviton)? Exactly the same issue: https://www.youtube.com/watch?v=y83BS_mK9GE Th

Damn, best products are always in the future :-) Oasis looks very capable and juicy, looking forward to get my hands on it.

My tests show it's slightly slower than Pi 4 and significantly faster than Pi 3 on CPU performance. 1T Coremark: Pi 3: 3504 Lichee: 6900 Pi 4: 7938

I tried it at the beginning, but found it quite complicated. A the moment Hugin is used, which works nearly perfectly, especially on XY stage where you can disable frame rotation optimization.

Power consumption and cost. 10 years on a battery is very hard to achieve for microcontroller. https://sorwatch.net shows that : with much more advanced microcontroller (much more modern tech.node, low power features) - it only

I've seen some made in Thailand. I would expect chip itself & quartz oscillator made in Japan.

Yep, this is my understanding. Also, world practice shows that noone ever got into troubles for posting chip pictures, and in 10 years noone ever contacted me to remove any photos. But companies do get intro troubles for trying to do copyca

I am the author of these photos... If you have a sample of rotten disk - you can send it to me and I'll take a look. Contacts are on the site. Now my hardware is better, CD and DVD are easy to observe without physical damage. I also ca

They are indeed enhanced, but about 2x, not 10x. At the time of the writing I was increasing saturation on all photos a bit in postprocessing. Now I am typically making photographs with RGB illumination which increases saturation optically

Wow, nice memory! Even I missed that. That means HA17555 is most likely also fake.
