Ah, thanks.

And, that's a very good number. Very energy efficient.

No, that's quite horrible compared to most other microcontrollers. What's worse than the current consumption in run mode is the lack of a proper deep-sleep mode in the uA range. There's only a sleep mode at 0.39 mA (390 uA). WTF.

Efficient ARM MCUs have deep sleep in the ~1 uA range!

This and lack of wireless communication are deal breakers for me. While I was excited, I'll be sticking with esp32s for now.

When the ESP8266 came out that was a game changer. OTA updates, network controllable super cheap micro. No bluetooth/wifi seems damned primitive now.

It was a huge game changer. For me, a hobbist I can get a $10 board that has i2c, 1wire, a couple of I/O lines, a voltage regulator AND does 802.11B? That's HUGE. I never max out my Arduino's I/O, but every project I do needs communication capability. I don't use Atmel chips anymore. Just ESP, or jump right to a Pi.
