Thanks, I am having setup issues at the moment myself with the M5Stamp that is driving me crazy.

Deepsleep and power saving modes are yet to be worked on because I keep getting distracted.

Delete the driver, shutdown the Mac fully, total power down (not log out or restart)
Turn on Mac install the driver the immediately fully power off the Mac again.
Power back up and try again.
The drivers are very finicky
works with OSX 10.14 but 10.15 is finicky again.

I'm running a MBP 2012 Catalina

It's not a usbmodem, that why it fails.
It should appear as tty.SLAB_USBtoUART

have you shut your computer down and restarted it since installing drivers?

Nice, thanks for sharing.

They are available only as PH2.0 4P connectors you can order them from china or on eBay but they are white SMD mount devices as you can see in this image.

The coloured ones I are spare from M5Stack projects and haven't been able to find a source of them yet.

If you still can't find them message me I can sell white THT ones for GBP £4 for a pack of 10 but there will be P&P to be paid on top of that price.

Hi, Adam here.
This is not an issue with the m5stack devices but is a known issue with the host computer and the driver.

There is a known conflict in both windows and OSX where there is an existing driver preinstalled which corrupts the installation of the the new driver.

Have you shut the computer down after installing the driver and restarted the computer afterwards?

Search the forum for the "Cold Boot Method"
The API number should be shown on the screen once the wifi setup on the device is complete.

Here is my work in progress book https://github.com/Ajb2k3/UIFlowHandbook/blob/master/quickblockref.pdf that should be able to help you.

The M5Stamp uses an ESP32 PICO D4 and so any library that supports the Pico D4 is usable.
You just need to make sure to define the pins correctly in your code.
StickC and Atom are both Pico D4 and should be ok but will have different pins defined.
