Yes, they exposed the ESP32 SPI pins on their unstable board. Why do you ask?
The worst part is they're still selling the trash. And when you go to the forums to ask them for help they blame it on the ESP32 being "unstable and weird" - they actually said that! tossers.

If they expose directly the ESP32 SPI pins, how could you blame them?
I mean, assuming the chip is correctly powered, if the SPI does not behave as it should then it cannot be a problem of the board.
Also, in my experience, interfacing SPI displays is tricky.

My first thought is it wasn't powered correctly, and my first suspect is cheap capacitors or otherwise cheap voltage regulation. That's just a guess though, it could be anything. These aren't exactly simple devices despite the cost.

I have used the standard ESP32 board for a complicated project using I2C, SPI, Wifi and ULP code. Worked like a charm, never noticed anything weird or unstable about it. Probably a case of wanting to shift the blame to someone else.

Get back to me once you get an RA8875 to work with it. I'll save you some time. You can't do it. I can't do it. The guys at Nuts and Volts couldn't do it.
Because it's broken.
SPI may have worked for little non-sensitive devices. It will not work with the RA8875 40 pin TFT touch.
Adafruit is overpriced trash.

No worries, I will follow your advice and never buy an Adafruit version. 
As to the original ESP32's version: SPI really did work well on that. I used it quite a lot to shift a lot of data to and from the built in Serial flash, thousands and thousands of recorded analogue data samples which were neatly sent to a remote server using the WiFi component. Really nice performance for a 7...8 Euro unit.

I love the chip. It's solid, regardless of what Adafruit says. The platform is gold.

I don't think I would condemn them that hard. I have never purchased any microcontrollers from them but have bought some devices. Their programming libraries are good for starting out. I am using a couple of temperature modules and a Temp/Humidity/Pressure module for an exercise to use Blazor, running on a Pi, as a dashboard. Started at Adafruit. No worries. Now, the temp module is $4.95 from them and $0.77 from Alibaba (+ $1.75, 30-50 days shipping). I would guess that all of that stuff is sourced from China. I have never tried to get support from Ada, but I guess you could view your experience 2 ways. One way is they were honest with you, and maybe ask for your money back. The IoT world is full of hype, cheating, and lying as well as good stuff. I like the good stuff (always look at the datasheets).
Like they say: Good, Cheap, Fast: pick any 2.
Pi's rock and start at about $8.
The I2C bus was never really intended for the way we use it, FWICS.

This is merely a parade of joy.
These selections, on the other hand, and political and I warn away those who don't want to enter this soon-to-be-locked down thread.
Also relevant from the very self same movie:

I guess a good portion of the USA will demand the movie be banned. Especially in rural states. Well - the book burnings have, fortunately, been averted.
And the rest of us ? We can have a good laugh at it and get on with the business of living.

You are out of line, Balboos. Your post is political and you know it.
If I posted similar posts, Sean would ban me for good. You do it, nothing happens.
Double standard.

You did not see, in person, the joy in the streets I witnessed.
Apparently, nationwide.
It's an event - an experience - that cannot be; should not be - forgotten.
What is telling, however, is you're making yourself some sort of victim-to-be, some sort of martyr in the making. I will skip enumerating from the pathetic-yet-laughable script, of the same nature, read aloud by what I see as "the other side".
There's a bunch of people, not all of them in Washington, DC, that just plain have to get over themselves. Or, at the least, reminisces about their past posts and realize that "what goes around comes around".

not my point. my point is that I have already been banned on this site. I have also been told my next infraction is a ban for life.
I am shedding light on the double standard. Certain members get away with EVERYTHING on this site, other, do not.

I've been wrestling with a problem all morning for what I thought would be a simple clock that also fetched weather information and exposed a tiny website on the home network at http://clock.local that will get the time and weather information. Simple, right?
The trouble I've been having is trying to get this thing to do WPS connect in the background. Everything has to be interrupt driven because I have no threads/scheduler and that's fine, but then I basically need a coroutine (like yield in C#) around all of the call backs because i have to ...
and I just figured out the solution.
woo. I'm leaving this here because i love when that happens.
Anyway, I love not having to deal with threads. I love that callbacks are safe to set global variables from.
Everything is so bloody simple. Yay.
But also, everything is so bloody simple. Boo!
Expect more articles. These things should keep me in material for at least the next month.

One problem with that is garbage collection. By nature garbage collectors tend to want to reserve a lot of memory. It's possible in theory to do .NET on a limited host, but maybe not something so limited as an ESP32. I could be wrong.
C++ isn't so bad, especially when coding these little things. There's no room for templates (what C# calls generics) so the code isn't actually that confusing. Most of it is C ish. There's very few reasons to do pointer ops so you won't typically be using things like * or -> except maybe * occasionally when dealing with strings.
Another option for some of these things is micropython which is python with a stripped down runtime.

You won't even get to the GC problem until you solve the bloatware problem on both fronts!

Yeah, although the CLI itself is pretty compact, so if it shipped with a stripped down CLR i think it would probably be fine but for the GC.

It is C++: templates can be used and have their usage (possibly you mean STL containers and the like...).
