No one is scalping Pis. They simply aren't valuable enough to scalp. There is a massive electronics shortage, in case you haven't heard.

TFA had a quote about them being overpriced on Amazon. Translation: people are indeed scalping them.

Explain how you know they are being scalped rather than the low supply increasing prices.

> but the lack of GPIO It's easy to hack a GPIO together using the USB interface or I2C interface that's inside every HDMI connector.

On-SoC based GPIO driven by register access is pretty dramatically different from GPIO driven over a bus in terms of timing. Also you need a microcontroller at the other end of the USB or I2C. Which means... you need a microcontroller anyway?

You can use a dedicated I2C controlled GPIO expander chip at the other end. For example, [1].

This works in the tens of kHz. Indeed, for high-speed applications you need a different approach. But in that case you probably also want to run a realtime-OS ...

The difference is, there's been an ammo shortage for like 10 years now.

I don't get it. How is that possible? Is it just not profitable to sell ammo? Why aren't they scrambling to meet demand like a normal industry?

Regulations. Dealing with explosives. Capital costs with uncertainty of payback.

If you ever find out, let the rest of us know. It's been an open question for a long time. Manufacturers have been making more and more each year, but still no where enough to meet demand.

Are there any alternatives to RPs in the <$100 range that are more available?

I just checked on digikey Beaglebone Black revision C is way less than 100$ and there is thousands in stock.

I've used Beaglebone's in industry grade projects. To my knowledge they are still in use after several years of operation with no hickups.

Went to the boston one 3 times in the past month. Didn't have any kind of Pi there.

Did you ask anyone? I’ve found they often don’t have stuff out but do have it in the back.

Never tried! Maybe I'll try next time I'm in the neighborhood. Been dying to get my hands on just one pi zero for a project for months now :(

Can you recommend one?

The thing to do here is: Sort by rising price, note the SoC names, look them up on their respective "linux mainline kernel port progress page" (links below), and then look in the vendor sub-folders of the mainline linux Hardware compatibility list ( https://github.com/torvalds/linux/tree/master/arch/arm64/boo... /vendorname/) to look for the DTS of the ODM name of the board. Then you'll need to just figure out a way…

Thank you, that's really helpful.

No problem. The approved resellers are sold out and sellers you've never heard of are selling them at a ridiculous markup over list price on Amazon. That's scalping.

Surprised they are prioritizing 2gb. Much of online chatter recommends buying 4 or 8

2GB is their cheapest and most popular model. At least it used to, nowadays it's probably the 1GB model which they've recently re-introduced to deal with the chip shortages.
