@m5stack Thanks. If the other solution I am looking at does not work out I will do as you suggest. Thanks again.

@m5stack. Thanks. I am able to do is connect my Arduino Uno to my PC and attempt to upload a program. I have tried reducing the speed to 115200 and the upload still failed.
Even if I had been able to successfully upload a program I have still have not been able to find any information on how to connect the Arduino to the Servo Module (I can see there is an ISP port but with no information anywhere on how it connects to an Arduino).
Thank you for your help but because there is a total lack of basic guidance for the novice user I have decided to abandon the idea of using M5Stack and will seek another way of achieving control of my servos.

m5stack and lukasmaximus. Thanks for your responses. I have followed the instructions from the link and hopefully have loaded everything required, including the CP210 x64 Driver but ‘lukasmaximus’ suggests I might not need it. There was one point where I had to put my thinking cap on – at point 5. There are options for M5Core and M5Stick, M5StickC, Atom Matrix/Lite, and then in larger type ‘M5Stack Library’. After this there are options for M5Core and M5Stick, M5Stick-C, etc. but as the M5Core section called for selecting M5Stack I searched for that and installed it.
I followed the page on: https://docs.m5stack.com/#/en/quick_start/m5core/m5stack_core_get_started_Arduino_Windows?id=_1-click-windows-zip-file-for-non-admin-install-to-download-arduino-ide and loaded the Example – ‘Factory Test’ (although it might not be of much use if I don’t have the right display shield). It seemed to compile OK but when I uploaded it I got the message:

Connecting......................................____An error occurred while uploading the sketch
A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header
This report would have more information with

option enabled in File -> Preferences.
I followed this latter suggestion and the Fatal Error re-occurred with 40 pages of error messages none of which help me! I am now at a loss as to how to proceed – HELP!!!
Lukasmaximus, you suggest there are alternative ways to communicate with the Servo module. I have not been able to find any information yet on the architecture for connecting to the M5Stack system. Assuming I can get the Arduino to work, where do I find info on how to connect it to the M5 Servo Driver Module. I see six pins in the side of the module which aren’t for servos but have not yet found which does what. Another point, there is some different info on what voltage should be connected to the Module. I see the Banggood advert shows ‘6-24V’ then specifies ‘5-7.2V’. The M5Stack website spec. for the Servo Module quotes ‘6-12V’! Any help would be much appreciated. Thanks.

I have been looking out for a system for controlling several servos on my miniature railway. I found the 'M5 Servo Controller' advertised by Banggood and looking at the description it seemed as though it might be suitable. I looked at the M5 website to get more information and although there is lots on the individual modules, etc. I have not been able to find any basic information on the M5 system and what it can and can't do, e.g. it would seem it has to be connected to an Arduino processor?

I am not particularly software literate but have done some very basic Arduino programming but the M5 seems to be very complicated, e.g. having to use ‘Easyloader’, and download CP210x and follow very complex programming instructions, etc. Also, I can’t find any information on how to connect the M5 Servo Controller to either an Arduino or a PC to facilitate programming for getting it to control my servos.

Is there any very basic information available which would allow a novice to be able to understand what the M5 System is, what it can and cannot do, and guide me with very simple instructions as to how I could use the product/system to simply allow me to have 12 buttons each of which commanded a servo to move in a pre-programmed way?
