It’s a pretty swanky looking chip.

I’ve been following the guys who write the Arduino code for the ESP’s, they are working on the port as we speak. The new version is getting good feedback too with lots of extras and abilities…
Once the code is released I think we’ll have to have a play with a couple !

Having RTC makes a huge difference for me

Need to see the data on the RTC as some of them are appalling at keeping accurate time. The fact they have made a big fuss about the RTC I would hope its a proper one !
The old ESP8266 has a basic RTC but its just a tick counter for doing ‘Sleep’ really + you can see its not accurate even over a short count like 60 seconds.

Think you’re in luck… from the spec sheet
- External 32 kHz crystal oscillator for RTC with calibration
- Two timer groups, including 2 x 64-bit timers and 1 x main watchdog in each group
- RTC watchdog
That looks Proper !
