      I'm designing a battery-powered lamp for tables with M5StickC and,

      1. Can I replace the 80mah lipo with a 3300mah? (I don't want to use the battery HAT)
      2. How do I disassemble M5stickC beyond the 2 screws? (It's not easy to lift the board and get access to the battery.)
      3. Are there libraries to program RGBW neopixels for UIFLOW?(https://www.adafruit.com/product/2858)

      Thank you!

        Hello @akshaypatil

        1. what exactly do you mean by 'replace'? You can 'attach/add' any battery on the outside, but almost any larger capacity battery will not mechanically fit inside M5StickC.

        2. AFAIK you cannot lift the two boards without separating them first - that is what I did when I took these pictures.

        3. I don't know.

        Cheers

          all you need to do is connect 5V directly to the led strip between the M5StickC and the led strip.

          UIFlow, so easy an adult can learn it!
          If I don't know it, be patient!
          I've ether not learned it or am too drunk to remember it!

            @felmue Thank you! Sorry for the late reply, got busy with something.

            Which ports do I add the battery externally? To "bat" and "gnd"?
            I was going to leave it barebones since it's not easy to find an alternative esp32 pico kit with a battery charging circuit onboard. (tiny tiny size)
            Would be cool to have an esp32 mounted on top of a li-ion cell, like how they have the protection circuits.

              yes, 'bat' and 'gnd'. I suggest you also check out the M5StickC schematics.
