U.S. availability

PyBoard D is only listed on the official store, based in the UK. The international distributors, such as Adafruit, Sparkfun, and RobotShop don't list the D on their websites, only the v1.1. Can the D only be obtained from the UK?

Thanks.

Re: 20x4 LCD

... and not upload it to esp32? And then it gives an error that the module was not found. I use EsPy and Thonny IDE. There are means with ampy (Adafruit) that allow you to run code, from your computer, on the ESP32 - look at the "run" option in the ampy documentation or help. I would imagine ...

Re: MQTT connection and client.check_msg() problem
