Max power allowed on the USB-C port #259

Closed bartissimo closed 1 month ago

bartissimo commented 3 months ago

Hi,

Can you please advise what the maximum power is you can put on the USB-C port (via USB cable) without damaging the T-Display-S3?

5V * ?A = how many watts max?

Thank you,

B.

There is no maximum requirement, only minimum requirements. A regular 5V 1A adapter is sufficient.

So it is technically not possible to overcharge and damage the device by using a high power USB-C adapter?

I can use any adapter e.g. a 60W USB-C one?

Listen, You can use any high power supply as long as it is no more than 5VDC and supplies the board with no more than 1A, i.e. 5Watts. Most ESP32 GPIO outputs are rated for no more than 20mA, and the total GPIO draw per chip is not more than 200mA. The boards 5V and 3.3V pin traces may not be able to handle 1A without peeling off or fusing open. Any large load, string of RGB, Motors, etc. should be powered from the source 'parallel' to the USB, with common grounds, not From the board.
