Use as JPG RGB MODE
For example, you can do it with GIMP.

New CH552 firmware for Short-Wifi-Issue of M5Atom/Stick/TimerCAM/etc. : About 9 months ago

Hello @RolfF

It's a design mistake.
It is a basic mistake to add 5V to 3.3V system.
5V enters the RF circuit, causing deterioration or damage.
There are many cases where ATOM has already broken.
