ESP32-S3-BOX LITE?

Are the 3 buttons on the front programmable? I would like to use this micropython.

I.E What are the GPIO numbers for the buttons? I looked at the docs and the schematics but was not able to figure that out.

esp32 s3 box and micropython - printing to the screen

Howdy! Wondering if anyone has used any of these esp32 s3 boxes to run MicroPython? https://www.espressif.com/en/news/ESP32-S3-BOX_video I have been able to flash the ESP32 S3 BOX lite for MicroPython, which is great. But I do not know how to print to the screen. Or any details about the screen? I t...

LILYGO TTGO T4 V1.3 ILI9341 2.4 inch LCD Display

Howdy.

I got this new board:

https://www.tindie.com/products/lilygo/ ... d-display/

It's very nice and easy to use.

I think it's a bit new. Anyone seen a 3D printed housing for it?

I tried https://www.yeggi.com/ but didn't find any real hits.

Thanks!

D1 Mini NodeMCU ESP-WROOM-32 to ili9341?

Howdy. Just bought this ESP32 D1 Mini: https://www.amazon.com/dp/B08RDDFWFJ Trying to connect it to a 2.8 inch ili9341. Are there any good instructions for this? This seems like the pinout: http://www.esp32learning.com/wp-content/uploads/2017/12/esp32minikit.jpg and this seems like a good connection...

Re: USB to TTL and BreadBoard Power supply?

Will try a new adapter as soon as I can locate a good candidate - Thanks!! I tried a 12 V / 1 amp. It did not make it all work. That's OK. The reason I was doing this was because I thought there were power issues but seems like I am making worse. FWIW, I put in all back simply using a USB cable as ...

Re: USB to TTL and BreadBoard Power supply?

What sort of supply are you using with the red board? I can't tell if there is a wall-wart connected to the connector at the top right. That supply should be >= 700 ma, preferably a 7 to 9V, >= 1A supply (I read that 12V makes the red board run hot.) The red board is probably like most of them and ...

Re: USB to TTL and BreadBoard Power supply?

Are the grounds on the two supplies connected? Without connecting the breadboard and USB grounds, they have no common frame of reference. Thanks Craig. I replied but I don't see my post yet. I am reposting now. In short, they were not connected. I was thinking they did not have to be (I then resear...

Re: USB to TTL and BreadBoard Power supply?

Could you make sure power supply of FTDI board is enough? As you know, supply current is required to be at least 500 mA for ESP module. Thanks. So it looks like for this board, in 5V mode the maximum current draw on this pin is approximately 500 mA. On checking it seems like I was getting 20 ma fro...
