I’m trying to use a RFM12B module in order to control some radio switches (hopefully not rolling code type - I do not know right now).

My questions are:
- the 10k pull-down for spi are a must or can I ignore them?
- the 4.7k what are good for?
Thank you for your help, and please excuse me for being a hardware noob.
