Hey Sprite,
All unconnected lines are connected to ground and all connected lines go through a series 33R resistor
We are also not using the lowest bit of green (G2), as we were one pin short and needed to drop something

ESP32S3 RGB565 LCD Screen Flicker
Hi,
We've been having this issue with the ESP32S3 driving a RGB56 IPS LCD where what i can only describe as the screen flicker. Such that the brightness seems to go up and down very quickly. What's odd about it is it only happens sometimes, and its severity (the amount of flicker) can be barely ...

ESP32S3 RGB LCD 565 red issue
Hello,
I've been working on making a LCD screen that uses st7701 SoC with the ESP32S3. I'm using 16 bit data lines with DE enabled. I'm using RGB565. I've created a screen with lvgl to test the colours. As can be seen with the 2nd image with a black background the lines appear how they should. But ...

ESP32S3 inbuilt jtag pin protection
Hello,
TLDR: As the USB D+ and D- will back drive into the ESP32S3 will it damage it when ESP32S3 is not powered on?
I'm in the process of designing a PCB using the ESP32-S3-WROOM-1 module. Now i want to power the board via a 12V SLA battery. The board has the necessary circuitry to step down the ...
