LILYGO TTGO T5 2.66 inch E-paper device

The device does not turn on (device leds stay dark) when connected to my computer.

1. Check you have a USB to TTL (T-U2T) connector connected between the device and your USB cable.
2. Check the device is not faulty by connecting it to a power supply, instead of the computer. The red power led should light up.

One solution is wait until all folders and files have synchronised with iCloud before building.
