I struggle to understand the appeal of these more premium ESP32 boards. I’m gonna throw the same code on it. It’s an ESP32 either way. What exactly am I buying here for that 3x price

Re: The Nano ESP32
#92Tangent, but can anyone advise how low (and small) in the Arduino lineage one can go and still have the ability to run a ~2-3" touchscreen and power animations at (say) 10 FPS?
I have a project in mind, but I've struggled to find this sort of practical answer oonline...

That would be dependent on the resolution of the display

#94Earlier quoted context omitted.
You (usually) don't use an Arduino in production, you take the ATMEGA chip, or in this case an ESP32 and you make your own custom board from it.
This doesn't answer the question: which industry professionals prototype their embedded products using an Arduino?
Like, you want their names?

#95Looking at how much our school had to pay for Amstrad PC1512 computers, all the ongoing discussion about Nano ESP32 price feels like a joke. You really think that paying $20 for something more powerfull than a PC1512, which when considering inflation, would cost $1722 in todays money, is really being robbed?!? Really, what a wonderfull thing that for $20 I can get something more powerful than what I used to play Defe…
But considering competition wouldn't Microbit be a better fit both for kids and even for students? Price is 10 GBP but you get also accelerometer, compass, 5x5 led array, 2x push buttons, 1x touch button, microphone, speaker, bluetooth le. You can power it with USB, AA battery pack or CR2032.
You can program in scratch, javascript, python and even c++. You can even change firmware to Zephyr RTOS if you want to do some low level stuff.
On top of that you have big ecosystem of extension boards or even robot kit. And tons of open source projects

Let's say 240x320.

It would an alternative yes, we don't need CPU monoculture.
Re: The Nano ESP32
#98It's almost as if Arduino is sherlocking Adafruit. They have offered ESP32 in a small standard-ish form for some time along with basic iot cloud logging services. Adafruit has also used and contributed heavily used libraries to Arduino.
There has long been overlap better Adafruit and Arduino devices.
Even the first Arduino Nano where an Adafruit idea/product

On that logic, I'd be happy to sell you an iPhone for triple the price.

People who don't want to mess around with low level configuration. For me, using an Arduino is the equivalent of prototyping a software in Python instead of doing it in C.
I haven't used any Expressif product, but is easy to find a problem or a bug while programming a MCU if you're new with it, and you don't know exactly what registers you need to edit to configure to set up the hardware correctly, or if there are hardware details, like the use of multiplexing in pins, to deal with.
With Arduino you can forget a lot of the smaller details, and you only have to know what pins to use, how you want to use them, what devices use, and the simple functions Arduino gives to you to use them (which are commom across most of boards).
