ESP32-TV Version 3 - Is it done?

The good news is - they work! Everything is behaving as expected and the new stuff on the board is also working.

But I'm still not completely satisfied. I think there's room for version 4 - what do you think?

0:00 It works!
2:50 We have a microphone!
4:46 SD Card Performance
9:24 I'm still not satisified
10:13 Some Unexpected Inspiration
13:23 Bonus Content!

These are both a work in progress - Use at your own risk!

I've been following this project from the beginning, and the progress you're making is astounding… Really learning a lot… And I'm looking forward to incorporating some of your stuff into my project… Well done and continued success!

Great to see how far this project has come. That non-standard header thing on the screen is such a pain... well, if you get a touch screen out of the rework it might well be worth it. If you're not using sufficient inputs at the same time, a MUX might do it, otherwise I think you'll be stuck with an io expander--going to have to use it only for slow signals...

6:57 - Was listening while eating lunch. Nearly choked on my salad. LOL

Nice project! One of the possible solution for the lack of GPIOs is to add port expander. You still have some space on the PCB, so all the LEDs, power enable signals etc can be handled through the expander.

The alternative screen only uses the same amount of pins as yours really. You could ignore the touchscreen pins, and you can connect /RST to the reset circuit on the ESP.

Well done getting all the bugs out to let David play with balls ROFL! I can see this format being a quite useful with the likes of Home Assistance Assist, it brings to the world a true open source voice assistant with useful video & image playback.

Wow! I have no idea how you can pump so many bytes in such a short time to the display.

Great project
Thanks for sharing your expirences with all of us :-)

[kgchrome]

oh man, this would be great if it could stream from a security DVR as a portable camera monitor. imagine security guards with the ability to patrol with a link back to a camera feed, for example.

Great board. As your not using touch, why don'tyou just not wire them up? or if you do need touch and timing isn't a problem use a PCF8574 8-Bit I/O Expander with I2C and access the touch that way. It worked for me.

[ExpressiveImagery]

This is a very cool project. Thanks for sharing this and your journey in creating it. I see you are using the ESP32 module that has the shielding can around it. If you are not wanting to worry about EMI then how about switching that out for a bare ESP32 so that you have all the GPIOs available for your needs? My next PCB design challenge will feature a bare ESP32-S3 😅

[GarrettBlackmon]

This is so cool man! Any plans to finish this project?

I'd love to get the parts for this and have a little tv chasis 3d printed to assemble. I'm more focused on software, custom pcb design is a bit over my head but if I could buy the things needed to put this together I'd love to play with the firmware and have a little desktop toy that constantly plays futurama on repeat 🤣

[Madmax]

But where is the TV part? I only see a video player. 😁
Great project! 👍

Do you have any recommendations for Bluetooth audio to the MAX I2S amp??

[KimasM]

I not 100% sure but there are pitches that are ment just for soldering those ribon cables directly to PCB's and differrent ones with using with socket. So it could be a case that this screen was never ment to be used with connector in first place that is why connectors doesn't exist for them. I have seen on Aliexpress some of the sellers list same screens with different connectors and specify like PCB solder and for connector with ribbon reinforced even with plastic to not get damage

[leonardsmit]

Rick Astley! The board is truly done ...
Amazing project.

[chethiyawijewickrama]

This is so cool, would you like to share the schematic design with me

[SojournerDidimus]

Can you perhaps save pins with using an I2C breakout to move speaker and microphone off of the IO lines?

[TheEmbeddedHobbyist]

nice just need two one ofr each eye now
if you drop the SD card access doen to two pins. will that not slow the access times down. R u transferring that data over a 4 bit bus?
