Is there a minimum clksys speed for gateway or nodes?
-
Hi,
I'm curious to know if there is some practical minimum system clock speed for either a gateway or node?
At the moment I don't have any battery operated nodes but I plan on having them in the future. It just seems like something that would be good to know when planning a design.
Thanks
John

Hello, no there is no minimum frequency but for a serial gateway I would keep it at 16MHz to avoid any missed messages. It also allows a high baud rate on the serial connection.
For battery powered nodes I use them mostly at 1MHz, there's not much interest going lower as you get no more gain in allowed voltage and not any significant gain in power consumption while the processing time increases.
