Yes, you’re right,
I own the rfid reader module you’re suggesting. It’s tested and it works well. it’s up an running in 5 minutes, but:
1-I want to connect this rfid reader because I’m introducing myself to the world of microcontrollers, electronics, etc…and this rfid module seems a good place to start learning to integrate I/O devices. Today is an rfid module, tomorrow will be another rs-232 or a wiegand module.
2-It seems that it has a longer read distance
3-In wiegand mode, the program does not have to constantly read rs-232 for data, it uses Interrupts to signal the data (if I understood right).
4-The anntena can be placed appart of the module, and can be replaced/improved
5-Can be used as an extension of other modules that accepts wiegand inputs/outputs, or used with other boards.
A) Where I can find if it is safe to plug a 5v signal to input pins?
B) can I configrure any GPIO ports as interrupt port, as explains in
I just want to be sure my board will not become part of the decoration of my house!
Many thanks for an answer, I’m sure it has been asked or it is documented somwhere, but for the moment, I’m a bit lost.
Again, thanks for your patience.
