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

Re: The Nano ESP32
#22The price of these aren't quite as egregious as the incredibly dated ATMEGA8-based Arduino Unos, but these still aren't really priced competitively to other offerings on the market. This is even considering other ESP32-S3 boards.
why aren't we seeing feature-rich dev boards based on the same platforms ?

What's the difference?
The OG ESP32 and successors esp32-S2 and ESP32-S3 use an ISA from company Tensilica called Xtensa LX6 (LX7 for the S3). The ESP32 C and H series use RISC-V. Xtensa is pretty well supported by compilers at this point, but RISC-V is on the rise and will have better support going forward. At this point in time, the S3 is the speediest ESP32 and is well supported, so it probably doesn't make a big difference. ISA: https:…

there are new 2022-23 cell phones available for $50-70, including the cameras, battery, display, case, gps, DAC, usb, radio, accel ... why aren't we seeing feature-rich dev boards based on the same platforms ?
Number of units sold has to be enormous to make a profit on low margin items.

It's not just this, but also that Espressif CEO's expressed their desire to focus on RISC-V[0]. Thus, a new Arduino platform is being created out of a deprecated family of MCUs, the Tensilica-based ESP32s. 0. https://www.eenewseurope.com/en/espressif-moves-exclusively-...

Re: The Nano ESP32
#28I 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
You would always make a custom board for an actual mass appeal product. If it's not a mass made product why do you care? Pick the easiest one regardless of cost.
This is essentially a dev kit. With the ability to easily mess with it. You don't care about the cost here because it's not really an expense when amortized.

#30To 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?
