Hi @ajb2k3 - Thanks for the reply. I gather it will take awhile before the M5 gets its hardware updated - the current NRND status is rather "fresh", from 10/2021.

@felmue appreciate the quick response and link - will have to wrap my head around the specific info to the Core2 configuration. I'll try my best to decipher it but don't be surprised if I come back with my tail between my legs and a few questions ;-).
Thanks,
Manfred

@felmue - UART2 has moved, really? the "current" espressif module data sheet in the download section of the current M5 Stack (Core 2) products still indicate GPIO 16 & 17. I feel a rabbit hole in the making....

In general, I would like at least 2 UART Rx channels. The M5 Stack comes with 3x UARTS according to the spec sheet.

From another internet source on the subject of UART and ESP32, I found the following:

• U0UXD is used to communicate with the ESP32 for programming and during reset/boot.
• U1UXD is unused and can be used for your projects. Some boards use this port for SPI Flash access though
• U2UXD is unused and can be used for your projects.

So, I thought, easy-peasy....I can count on being able to use UART1 and 2 - the M5 Stack (Core2) should be able to manage this, correct?
(I don't plan attaching any GPS-Module, etc, so....2x UARTs should be the minimum available)

But your having mentioned that the pin layout is different makes we question how reliable the M5 documentation really is (?).

Appreciate any feedback...also bookmarked your pinning page, thanks.

Hello Community & more importantly M5,

The most recent datasheet for the ESP32 Espressif module ESP32-D0WDQ6-V3 lists this module as "NRND" (not recommended for new designs) - apparently Espressif has updated its hardware. Is M5 planning to update their Stack products in the near future - and if so, when and what chip will be used? I'm looking in particular at the M5 Stack Tough and need to new what the available GPIOs, etc. will look like.

Thanks,
Manfred
