  • I'm looking for modules like the 07 and 12 - ones with castellated pads on them, so I can make a board and stick them down to it. Through-hole pins are a non-starter.

    How do I know for sure whether the modules have 4MBytes (32mbit) or 4Mbit of flash?

    Is the kind with the ceramic antenna better in terms of RF performance?

    @Ollie: How do you implement the 433mhz comms? Is it sending only, or receiving too?
