Hi, without looking into the schematic, I would say it is the voltage regulator. The schematics can be found on github. https://github.com/micropython/pyboard/blob/master/PYBv10b.pdf However, this is not a 8 pin IC. Thus without a little more information it is hard to guess. If it is indeed the volt...

Hi,

if the sensor communication does not require a lot of fast data sending, try the SoftUART approach.

I was able to talk to a serial display from a d1mini using this library.

Hi, welcome to the forum. Please try to be specific about the problem in the post itself. Screenshots on an external page my not work for long and then, this thread turns into a useless piece for other users. As far as I can see you misunderstood the import nature of python. If you use import networ...

Hi,

The toroidal transformer is rated at 6VA - it was the smallest stocked at my usual supplier (CPC/Farnell). It fitted in the box so I used it. A smaller one would undoubtedly suffice if you can find one. As for hand tools I was trained in metalwork where we were required to produce work in mild stee...

First posts do not allow bbcode as some spammers used it to send pictures not only of naked PCBs but of other naked things....
As we need to approve the first posts and they always open up full for approval, we had an office-rules violation from time to time
Now it should work for you

Hi and welcome, writing to an LCD display is not as easy as you tried. In fact what you did was to write ASCII to the UART port. However, even if the display is connected to the UART port it is usually not 'smart' on its own, how should it know what to do with the information you send? What is text ...

In that case go for a RPi instead of a micropython board. A Pi-Zero if it has to be small....

Hey Peter, sorry for being quit on this for a longer period. Nice to hear you had more success with the new modules. I will go an order some to compare your findings. Would be really nice to see what is the exact difference between the different generations. We might be able to ask the vendor. Somet...

To add to this miracle: Other projects seem to happily use the sonoff units. I searched but could not find any similar issues or threads for that matter. E.h. espeasy seems to supports them. However, the sonoff units had several hardware releases. I believe I still use an early version and I know Pe...
