MOSFET Selection
To make the system efficient as possible the Rds of the LED should be as low as possible. Having a logic level of 3.3 V on the board will make selecting a power MOSFET slightly more difficult - Most 5 V DC barrel jack PSU’s start to max out between 6-10 A (Though the connectors max current rating is a bit how ya going at that amount).
This guide retouched the info that I’ve learnt from the forum and uni: https://www.digikey.com.au/en/blog/how-to-select-a-mosfet-for-logic-circuits-or-gate-design
