I tried to connect my RFM69HCW to Arduino Nano 33 BLE, so that I won't be needing a logic level shifter to downgrade the voltage, since Arduino Nano is already 3.3V. Upon checking its data sheet and pinout, I noticed there's no dedicated pin for CS (Chip Select).
Which pin should I use as CS in the Arduino Nano?
Which pin should I connect the DI0 pin of RFM69HCW in the Arduino Nano?
