After reading a specific post on the Parallax forum I got interested in the Seeed Studio line of esp32 mcu's, I bought the cheapest one they have and I want to try and include it in an espnow network. It was $5 and is smaller than the end of my thumb.

I've flashed the micropython firmware to the device and tested it with a few simple scripts.

I have another mcu which I have had for about a year now which I have also flashed with micropython, this one is the Lilygo T-Display S3. I may make this my master espnow station.

It has a really nice 320 x 170 display driven by an eight bit parallel bus so it's very fast to update. This one is a little more expensive at $27 but I think the on board display evens it out for me.

Hopefully fairly soon I can post a review of how these two work together.

Very interesting. I can't wait to see what you come up with. I'm still planning on putting my stuff together. Just been trying to deal with some future house issues.

I re-read this and realized, I really need to look into this for possible 6502 / Z80 applications. Both systems use an 8-bit parallel bus interface by default. The Z80 actually has IN and OUT instructions that are designed to input / output a byte from a mapped 8-bit I/O port.

Hi Chris, I do really like this display, check out this channel on YouTube https://www.youtube.com/@VolosProjects he has some great ideas for display projects.
