Currently emonSD-03May16 (just!) fits on a 4GB SD card. This only leaves 40Mb free in the data partition for data logging and only 280Mb free in the root Linux partition.
All SD cards we ship via the shop including pre-installed in all emonPi and emonBase include an 8GB SD card with the data partition expanded to fill the card.
I’m working on the next release and considering just moving to an 8GB min SD card size. I think given the low cost of SD cards (in bulk 8GB cards were cheaper than 4GB!) I would not recommend anyone uses a 4GB card anymore. Using a 4GB card will just create issues with running out of space in the near future.
Do you think this is a reasonable move?
The extra space will create space for future dist updates and allow platformIO (for onboard firmware compiling and uploading) and HomeAssistant to be installed and configured.
