Hello @User1234567

1: The ESPAsyncWebServer seems to be pressing the M5Stack's ButtonA.

M5.BtnA.wasPressed() conflicts with WiFi

The MAX40200 is a great idea.

1. I want a power switch for M5Stack 700mA BATTERY MODULE.
2. I have switched on the Battery side.
   Example 1: AA, AAA battery adapter for M5Stack.

The library has been released!
It is a library that can be used in common with M5Stack / Core2 / Tough / CoreInk / Paper / StickC, CPlus.
Buttons, touch panel, IMU, 5V output on / off to external port, etc. are available. It can also be used with ESP-IDF.

Hello @Dieter_P

I don't own ATOM Lite (ESP32-PICO-D4), so I haven't checked it.

1. Does the problem occur when using WiFi?
2. You need to check the signal of GPIO39.
   ：

In M5Stack (ESP32-D0WDQ6-V3), there is a case where GPIO39 works without permission when using WiFi.
M5.BtnA.wasPressed() conflicts with WiFi
https://forum.m5stack.com/topic/3262/m5-btna-waspressed-conflicts-with-wifi
：

Supplement：
Example of using GPIO39.
M5Stack Basic (ESP32-D0WDQ6-V3)：PULL UP with 100KΩ.
ATOM PSRAM (ESP32-V3-02)：PULL UP with 5.1KΩ.
M5Stamp Pico (ESP32-PICO-D4)：PULL UP with 5.1KΩ.

GPIO is written in PinMap of M5Unified.

@lwtsde said in M5Paper STL Files available?:

M5Paper

Hello!

It depends on the accuracy of the 3D Printer.
M5 Paper requires high accuracy.
You need a high-precision printer.
The accuracy of the printer for amateurs is about 0.4mm width.
I think it is impossible because the accuracy is low.

Hello@F3l1x

In the example below I am using lcd-image-converter.
lcd-image-converter
https://sourceforge.net/projects/lcd-image-converter/
Select 8bit or 16bit for Block size and create xxx.c.
Use M5.Lcd.pushImage(x,y,imgWidth,imgHeight,(unit16_t *) xxx);
