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?

The only two examples I can thing of are not Arduino and not prototypes (these are production units) but the Wi-Fi module for Garo EV chargers is a Raspberry Pi with an angled GPIO header.[0]

Also, the Wi-Fi module for Ebeco floor heating thermostats is a custom PCB with a SMD mounted ESP32 board. They never show that side of the PCB in the photos online but I have one and that's what it is.[1]

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

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 ha…

You can use arduino with any of the cheap ESP32 boards as well. That does not distinguish this particular board, with it's 3x price tag from others.

Looking 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…

I agree. MCs like this are an absolute marvel of modern technology and the fact that they’re as cheap as $21 continues to blow my mind. It just seems disproportionately inexpensive considering how complex and powerful these things are.

This has not been my experience at all. Random cheapie ESP32 board bought off Alibaba performs/is exactly the same as expensive one with better marketing bought off Adafruit, Sparkfun, etc.

It'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.

What is "sherlocking"?

Is it battery friendly and is it handling deep sleep properly? No? Then this is yet another board with a esp32 (but overpriced)

The ESP32 notably does not come with monitor, keyboard, disk drives, or mouse.

To those that are in the embedded space, what are some websites that I can lurk to get a better understanding? Places to buy parts? Where do you start?

(assuming you are in the US). Go to Amazon, buy an ESP32 beginner kit, which should come with an ESP32 dev board, a handful of different sensors and components, and a breadboard and some wires. It will also have some sample code. Go through a few of the basic modern IoT "hello world" examples, like making a web-enabled temperature sensor. Then google for "ESP32 [foo]", where foo is some random idea that you have for…

I need some sort of basic guide to like, the actual hardware. Bought one of these but not keen to fry things accidentally...

Can you expand a bit on the value for the money? This board is $21 with headers... I've seen a ton of esp32 boards for much less. What do you think makes this board worth the extra cost?

It has Bluetooth, Wi-Fi and an IMU built in which is very useful for a robotics project I'm currently working on. Plus it has a huge amount of RAM and flash compared to an ATMEGA Arduino

Seconding this. Just not having to muck about with a second board for the IMU was worth it for me, but also having wifi onboard at a time before the pico W got released was good.
