No, and as a result no 😅 There is no battery connector or circuitry. A cyd powered by battery will require external modules/components I created an issue around this but I haven't made any progress since this |

I just built an esp32-2432s028 with a 3.7V lithium-ion battery, an MT3608 and a TP4056 in a 3D printed case. Unfortunately, so far only between 3 and 5 hours of running time. so far only LVGL display without interactions. |

There are a few things I would do different. On the photo with the battery and drawing they are around the wrong way and if you have the same case from AliExpress move the power module all the way to the edge of the case I used hot glue so I might move, and also might cut the case so getting the SD or is a little easier, I also found hot glue the wires to the board in place as they are very small contacts at t back of the USB and I have a very cheap soldering iron, |

do you need to have two usb ports? in your video the battery was charging via the pre-installed port. Is this because you wanted a dedicated charging port? |

I've been using a Lilygo T-Display-S3 for my hobby work, and you can plug in a LiPo 3.7V battery to the device. On full activity my 300mAh battery lasts about 3 hours. But more importantly, when you plug a USB-C cable into the device, the battery is charged - a red LED lights up, and then goes off when the battery is full.
Is there a battery connector for the ESP32-CYD, and does the USB connector handle its charging properly?
