So, I've been working on a little project where I need an RFID reader to enable the program on my Beetle board and couldn't find any info on the ISP pins so here they are.
RFID MF522-AN...BEETLE
MISO.................... MI
SCK...................... SCK
SS......................... RX (0)
MOSI.................... MO
GND..................... GND
3.3V...................... 3.3V
RES....................... TX(1)
On most RFID programs you can reassign the SS and RES so I used the RX and TX which relate to digital zero and one.
This leaves the other pins 11, 10, 9, A1, A2, and A3 for other I/O pins.
Hope this helps.
Hasta la vista..
