There is a project going on to ad a new pcb with an nRF52840 into the case as it is better in terms of low power. But it will take time till it is done
I like what I see, but where to get this price tags, could not find them on Ebay or Aliexpress. What I found is some offers of ED060SC4, replacement for an e-book reader. For this there is a STM32 library (github.com/PetteriAimonen/ED060SC4_driver). With your experience, what obstacles do I need to expect?
@@atc1441 the hardest part is how to trigger the node wake up, I understand your method. But so supprise node can wake up by the centre which send command (over the air, long distance, 5m), update and go to sleep. Curiosity about their solution inside ^^. With 2-3times update a day, battery can use for 5 years
Today the deep sleep of most MCUs is so low that this is not problem anymore. They wake up every 1 or 2 seconds and see if new data is available then they sleep again. That happens so quickly that it does not draw much power
I love your voice/accent for tutorials it's so relaxing and easy to follow :)
I wonder how much these cost in bulk
Wow, that's cool… Great Job, man!
Hello, Do you have a link to where you buy them at? There are a lot of them on aliexpress and alibaba.
Hey. ebay is your friend
Where can I buy the display?
Do you sell these pcb spi adapter boards?
I wounder if you can get in exchange for the original chip an ESP32 on a PCB with castellation in there.

That is a valid other option :) the screen looks nice
So cool, can we reuse the price tag. Still not know how they can make super power consumption? ^^ too curiosity.
They only need power when the image does change. After that you can disconnect the battery and will hold the image :)

Where do you get these? Are these available somewhere, or a local find?
Please write a mail to youtube@43u.de :)
What wire are you using to solder those connections?
Magnet wire basically. 32 awg.
Hello, thank you for your help. Can I buy one of your PCBs? Thanks!
I only got the pcb's but not soldered i can share these. The connector is quite hard to solder on.
@@atc1441 Thank you. I found something similar :
Waveshare E-Paper Driver Hat
What do you think about it?
The problem on that one is that the gold contacts are on the wrong side. I talk about it in the video
@@atc1441 You can flip it ... or not? Where is the problem? You don’t need to use the expansion thing.
No the connection would be wrong if it is flipped.
It needs to be a connector for the other side or a multi side connector
BTW what is the original mcu? I guess there is not enough information about it, or you would have already reverse engineered it :)
It is an 88MZ100 Marvell nda and stuff :-/ still trying to reverse it more
I would rather buy a breakout board...
Sure its some work but if no other hardware is around its a solution :)
