The board is not compatible with Wemos D1 mini (34.2 x 25.6 mm) and shield, but offers a more powerful solution with Bluetooth LE, battery support, and more I/Os. The Wiki is still work-in-progres, and there’s no that much information on the page yet.

Wemos LoLin32 can be purchased for $6.90 + shipping ($8.66 in my case) on Aliexpress.

    Not sure. I would not worry too much about those bugs, unless your application is specifically affected by one or more of them. Processors often have a list of errata.

    @GunterO almost definitely version 0. Version 1 is barely starting production. At some point it will probably transparently shift to version 1 and be impossible to tell, so hopefully they aren’t making tons that will stay in inventory all year.

    Got mine today, trying to flash Blink something with the Arduino IDE… the board does not seem to have an onboard led…
