    • RE: M5.BtnA.wasPressed() conflicts with WiFi?

      The cause is the ESP32 bug.

      This is a report of measures for the A button of M5Stack and the B button of M5Stick C to operate without permission.

    • RE: M5Stack Atom Lite: Long response times and wifi connection losses

      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.
