>easy to obtain hardware such as a Raspberry Pi !!!

MrGilbert 4y ago
I was surprised to learn that there is an actual shortage regarding RPis... I remember the days we were hording these things. "Maybe I have an idea some day, so I better buy two of them." was the motto. Wild days to remember.

  I ordered one in April. Hasn't arrived yet...

I'm not familiar with that book, but if the RPi is used to send or receive data over gpio, serial, parallel, i2c, ethernet etc. then the functions can be replicated pretty much on every SBC out there. Many projects/articles/books use the Raspberry Pi just because it's the most popular and the name alone attracts users/readers/buyers, but, as with many other projects, almost all can be adapted with minimal changes to work using other easily available, and often also a lot cheaper, boards.

  The comment you're replying to was making a joke about the claim that a Raspberry Pi is "easy to obtain", which has not been the case in a long time due to shortages.

    The one you're replying to was making the point that although Raspberry Pis may no longer be easy to obtain there are plenty of similar devices on the market.

      Yeah, I completely misread it.

  RPi tends to be the cheapest ARM SBC so many users don't/won't look beyond it.

    > RPi tends to be the cheapest ARM SBC Not true. It surely was many years ago when it was introduced, but other manufacturers caught up quickly and now you have plenty of alternatives. Also, don't mistake the RPi Pico with other models; the Pico is a really nice product (probably the most innovative one since the 1st RPi) but plays more in the Arduino field rather than with other Raspberries. It can't run Linux for example. Here are some prices of boards one can actually buy. All in stock (often hundreds of pieces available for each model), most cheaper than the Raspberry Pi models and all can run Linux. https://www.newark.com/beagleboard/bb-pocket/pocket-beagle-board-arm-cortex/dp/45AC6372?ost=pocketbeagle https://www.newark.com/beagleboard/bb-pocket/pocket-beagle-b... https://www.olimex.com/Products/OLinuXino/A20/A20-OLinuXino-LIME/open-source-hardware https://www.olimex.com/Products/OLinuXino/A20/A20-OLinuXino-... https://www.aliexpress.us/item/3256804217221880.html https://www.aliexpress.us/item/3256804217221880.html https://www.aliexpress.us/item/3256804758454704.html https://www.aliexpress.us/item/3256804758454704.html https://www.aliexpress.us/item/3256804758464897.html https://www.aliexpress.us/item/3256804758464897.html https://www.aliexpress.us/item/3256804126710955.html https://www.aliexpress.us/item/3256804126710955.html https://www.aliexpress.us/item/3256803404327789.html https://www.aliexpress.us/item/3256803404327789.html https://www.aliexpress.us/item/3256801502837883.html https://www.aliexpress.us/item/3256801502837883.html https://www.aliexpress.us/item/2255800412273026.html https://www.aliexpress.us/item/2255800412273026.html https://www.friendlyelec.com/index.php?route=product/product&path=69&product_id=132 https://www.friendlyelec.com/index.php?route=product/product... https://www.friendlyelec.com/index.php?route=product/product&path=69&product_id=244 https://www.friendlyelec.com/index.php?route=product/product... https://www.friendlyelec.com/index.php?route=product/product&path=69&product_id=151 https://www.friendlyelec.com/index.php?route=product/product... https://www.friendlyelec.com/index.php?route=product/product&path=69&product_id=282 https://www.friendlyelec.com/index.php?route=product/product...

They forgot to mention its a Pi Pico, the microcontroller. Those are not hard to find.

  The w version is a bit harder to find but not by much

  I don't think Hardware Hacker’s Handbook uses the Pico (don't have a copy in front of me) but it definitely uses a Pi 3+ as a demo target.
