RFM69 breakout board, capacitors?

Added by Rolf over 1 year ago

Hi,
some time ago I ordered a couple of RFM69CW modules + breakout boards. For I have only 3.3V environments, I took the "PCB only" variant. Later I saw in the assembling instruction: "Insert C2, C3 to improve decoupling of the 3.3V supply". What is the specification for C2 and C3, I did not find it in the documentation, nor a circuit layout?
Thanks, Rolf

Compared with the JeeNodes I would say C2 is 100nF and C3 is 4.7μF

BTW: the documentation is on https://jeelabs.net/projects/hardware/wiki/RFM12B_Board at the bottom of the page, just click on "Files" (Dateien when you have german as your language).
