I hoard as many spares as I can. Fun fact: for the first run of the Eurorack #1222, I ordered 100 pcs three times from different sellers only to have them come back saying to pay more money or cancel order. All of which I rejected on principle. I rejected an offer for $4 apiece that should have been $3.50 and ended up paying $7 in stead.

Im glad i picked up 10 before the shortage. with what some folks charge for nanos nowadays, you may as well get teensy or similar.
Same location, same listing at 39.99 back in January is now going for nearly 80 buckazoids

Except, Teensies are twice the price now too
yeah, but check this out:
20 bucks for 3, and they are WAY better than even a teensy.

Yup, it happened very quickly.
Definitely options out there. I got some of the LGT8F328P that are supposedly an “upgraded” and “mostly compatible” Nano with a 32 MHz clock. In the end, because of the Tuner code relying on the clock and the differences I had to rewrite the code and then half of them didn’t actually work in the end anyway. The 168P Nano can fit @lookmumnocomputer’s original Tuner code, but not @Jos’s with the nice startup animation…

Without checking, I’d assume power consumption is not in line with a Nano, which becomes a concern when you’re trying to not scare people off from buying your module.

Both codes can be very much optimized for memory… both code and data space…
I’ll bet a Eurorack #1222 @Jos’s can fit in a '168

Woah, and it has Bluetooth?
Normally I hate Bluetooth, but have thought of doing a module so I can modulate the synth using a Wii Nunchuck…
EDIT GitHub - hrgraf/ESP32Wiimote: Tiny Arduino ESP32 library for the Wii Remote controller yeah this is totally doable! Hmmmmm And it has a built in DAC? This thing kicks ass

As pointed out in the questions & answers section, the pinout shows 38 pins, but the product photo has only 30 pins. One photo says “Better than 30 pin ESP32 module” but that same photo shows 30 pins and some of the answers say what they received was 30 pins.
So who knows what the hell these people are selling.

I picked them up recently, I’ll report back unless I forget lol.
In terms of power consumption, it’s looking like it’s very tunable for different needs, but it sounds like you can get it to be less than the nano.
When I get this particular board with the ESP32, I’ll be able to do some a and b tests.
The power consumption should mainly come from wireless communication. If you disable that, the sleep modes etc might not even be needed. In an application where you would use wofo or Bluetooth, such as a midi to cv wireless deal, you might just power it separately, and not on the modular power rails.
This thing has a lot of functionality that’s great, but not necessary for all projects. Properly tuned, you have two cores that run quick with 512k ram. In terms of what I’m used to, things like a lot more adc etc is what you’d get from a teensy, but this thing looks suped up. You could probably make a whole polyphonic wavetable synth and output the audio straight from this thing.

I’m currently playing with the esp32 audio kit. Thanks for the power links.

There are also some tricks to reduce power consumption for arduinos

Watching with interest. Please do report back.

This, and any Atmega328P DIP packages are just impossible to find right now save paying these prices just for the chip.
I’ve been grabbing those green pill boards off of *mazon. They’re cheaper and more powerful than a Nano, but of course the non-avr architecture (and non-blue pillness of them) makes it so all open source code has to be adapted for everything.
Great for learning to code, terrible for finishing projects in a timely manner

Once I build a few units of a batch to make sure everything checks out, I tend to go into assembly line mode for the rest. To wit, this is 100 boards stuffed with 800 jack sockets:
