External Power supply for STEVAL-STWINKT1B

RMhap.1 · ‎2022-07-26

I wanted to know if there was any external power supply available to power the STEVAL-STWINKT1B board instead of giving it power through the laptop or the provided battery pack. I wanted to implement it in an industrial setup and keep it on for the entire week without the need to change batteries,

Any help would be appreciated.

Did you check the User Manual?

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

Hi @Andrew Neil Thanks a lot for your quick reply. Yes i am aware about the Voltage rating through USB but i was not able to find the current ratings for the adapter, Is it 2amps even for usb power?

If that was your question, why didn't you say so?

It's USB - so it will have to abide by standard USB limits.

Note that the 2A is the limit in the external power supply - not the amount that the board will draw!

If you're not using the battery, you won't have to worry about charging currents!
