@eliott I'm not sure about this product.
Are you asking for the exact firmware that shipped with your watch when new?
Here is a link to example sketches at the LilyGO repository:
https://github.com/Xinyuan-LilyGO/TTGO_TWatch_Library/tree/master/examples
To be sure, you may raise and "Issue" on this site, which may take a long time.
I have found that a nice inquiry at their office address works:
sales@lilygo.cc
Also LilyGO suggest this GitHub repository:
https://github.com/sharandac/My-TTGO-Watch
Hope this helps!

Yes. ESP32 supports CAN and these are featured S3 boards.

RE: Unable to make T-Display S3 work with LiPo battery
Sounds like the ol' GPIO 15 must be turned on HIGH issue.
This enables the display power and the circuit that uses and re-charges the battery.
I made a support repository for new users here:
https://github.com/teastainGit/LilyGO-T-display-S3-setup-and-examples
My examples are the simplest possible sketches that use the display, TFT_eSPI and Serial.print functions, as a sort of tutorial.
Hope this helps -TerryIf you are not running one of my sketches, you should add:
#define PIN_POWER_ON 15 // LCD and battery Power Enable
#define PIN_LCD_BL 38 // BackLight enable pin (see Dimming.txt)just before the setup and then in setup add:
pinMode(PIN_POWER_ON, OUTPUT); //triggers the LCD backlight
pinMode(PIN_LCD_BL, OUTPUT); // BackLight enable pindigitalWrite(PIN_POWER_ON, HIGH);
digitalWrite(PIN_LCD_BL, HIGH); -
RE: T-Beam SUPREME - Charging battery when off
@luffe LilyGO products...generally yes, they charge all the time while plugged in to USB.
You should conduct a simple test with your actual unit, as the documentation is very sparse.
(I could not find a schematic for your board)

RE: How to operate T-Display-S3 Touch out of the box
@danardi It is indeed annoying and it gave me trouble, but I figured out that you can edit the pinconfig.h that appears in the Arduino IDE off to the right with your own SSID and Password and avoid the ESPTouch nonsense. (this 'ESP touch" has nothing to do with the optional touch screen, BTW)
If you are new to LilyGO T-Display S3 I made a support GitHub repository here:

RE: Boot-Problem: LilyGO TTGO-S3 Touch
HotHead here!
So, the HotHead sketch works on battery, yes?
Could you post your temperature code here so I could run it on my LilyGO T-Display S3 ?

RE: How to flash T-01C3
@teastain2
(you need to cross over TX to RX so that the TTl TX is the LilyGO RX !) -
RE: JST-GH connector on T-Camera S3 ?
@jip The recommended battery is this:
Panasonic Lithium Ion 18650 3.7V, 3400Mah
You can put 5V into the two prong battery plug and the regulator will bring it down to 3.3.
The unit will still work, somewhat @ 3v. -
RE: Is T-watch 2020 V3 water resistant?
@ivan Hi Ivan, this site is a volunteer user community site and anything I say is simply "advice".
LilyGO make no claim of waterproof, but it seems well sealed.
I think accidental splashing such as washing hands would be OK.
Otherwise I would "Damp-Cloth" it as you say!

RE: How do your turn on and off the LCD screen for the T-Display S3 AMOLED board?
@roblatour An AMOLED screen has no backlight because each pixel is an individual LED, so printing a black image uses the least current.

RE: Using VSPI GPIO Pins for Interrupts on T-SIM7600E/G-H
@mijail-makaroff-0 They can be used as GPIO and therefore interrupts.
The old Arduino boards had dedicated I/O, but ESP32 uses a 'GPIO multiplexer'.

RE: Detecting USB Power in code on T-Display-S3
@hpro This only a community site, with mostly me.
You could try their GitHub repository and raise an issue:
https://github.com/Xinyuan-LilyGO/T-Display-S3/issues
Lithium batteries do not lose voltage as they are used up, They all of a sudden die!
My suggestion was to calibrate the voltage at USB conditions and anything less than that, accounting for ADC drift would indicate that it was on battery only, no USB.

RE: Detecting USB Power in code on T-Display-S3
@hpro You could...use the ESP ADC function on pin GPIO4 to read the Battery Voltage.
in my experience it shows~ 5V on USB and some lower values on Battery.
The ESP has a terrible built in ADC that is not calibrated, stable or linear...but it's free.

RE: How to mount the T4 S3?
@butane Hi!
I would say that it is intended to be mounted in a frame for a desk or inserted into a panel for industry.
This would be an excellent 3D printer project!
Maybe search the Net for anyone who has done this.

RE: I2C - wich pins for SDA and SCL
Hi! Any of the pins SHOULD be able to support I2C :
I would avoid the pins for the optional W5500 board as shown here.
