RE:
I kind of left it last night, but was curious to go look into and learn a little more about the ESP stuff.
It looks like the ESP I have is ESP-WROOM-32D. This does, if I’m not mistaken, have the 4MB of PSRAM.
Out of curiosity, just wondering if Bart had these same issues with his own controller, I went to look to see what he was using.
He is using ESP32-WROVER-E, which I believe has double the PSRAM at 8MB like this one for $10.78.
If this is compatible, I will buy one and test it on my machine in the Jackpot.
While I totally understand your commitment to making things lower cost, and we all appreciate it, what I wouldn’t want to see happen as the use of the Jackpot spreads is that issues related to memory, etc. cause massive amounts of support and headache for you.
After all, this is the brains, so if there is ever a place to spend an extra $7, this is it. If $7 makes it more stable, it is well worth the cost, and I don’t feel like it should be non-starter for anyone that is already willing to spend $500-$1000 building machines like this.
The last thing we want, and I’m sure you want, is $7 standing in the way of actually being able to use this fancy new toy we just created.
