Questions answered in NewMsg-RF905 manuals
Can the CSN pin be tied directly to ground when using a single RF905 module?
No, CSN is the SPI chip‑select line and must be driven high for the RF905 to accept data.
What is the current consumption in power‑down mode?
The module draws about 2.5 µA in power‑down mode.
