hi i need to add following to mega 2560
1 lan enc28j60
2 bluetooth hc-05
3 wireless nf24l01
4 rfid rc522
5 finger print scanner r307
6 display oled
7 keypad 4x4
8 rtc ds3231
9 sd card catalex v1.0 11/01/2013
10 wifi esp8266
is it ok to add all the spi modules in parallel on one mega 2560, if yes then what precautions need to be taken.
as mega has multiple serial ports, will that be helpful
i am new to arduino, was just fiddling, have been able to run the spi devices connected one at a time.
also one more though can i use the serial ports on mega AS SPI
