Hey!
Has 3 Qwiic Rfid readers with ID12 LA on. These have short reading distances. Sees that it only supplies 3.3V from Qwiic pcb. Can I feed with 5v from external supply to possibly increase the reading distance?
Sorry for my bad English …
Hi Stellan.
We’ve not tried this at 5 volts, but I don’t see anything right off that says you couldn’t use 5 volts as a power source. Just don’t exceed 5 volts.
Hey!
I tried to power Rfid pcb with 5v. Unfortunately, this did not increase the reading distance.
