      @hosky well, you could use the esp32 built in ADC to read pin 4 bat volt, or wire the 5V pin to a voltage divider and then to a GPIO, such as 16 and digitalRead it.

      Help with USB VID/PID for Circuitpython

      @zhang-lilygo As VID we could use USB_VID = 0x2E8A (that's the Raspberry Pi foundation) and simply need to request a new PID in the Google form, linked in https://github.com/raspberrypi/usb-pid . But this has to be done by the Lilygo company. Can someone from Lilygo please request this PID? We have a post from https://github.com/Xinyuan-LilyGO/LILYGO-T-display-RP2040/issues/5 that the request was done in May 24, 2022. But no PID so far.

      Can someone from Lilygo request the PID again? And a second one for the T-PicoC3? The board description is complete and working with Circuitpython 8.1.0 but it is not published because the PID is missing.

      @luki743 LilyGO T-Display S3, easy;
      T-Embed not so much.
      The T-Embed repository is here:
      https://github.com/Xinyuan-LilyGO/T-Embed
      You only need one GPIO and gnd if the sn65hvd230 is powered by the other device.
      CAN takes a single digital output (GPIO) from the ESP and converts it to "differential" + signal, - signal.
      The "Grove" connector maybe configured as CAN and maybe a few spare GPIO on that unpopulated development pad on the lower left of the image.

      @etolocka Yes, it does. It's the red component marked C3, which is a compact "ceramic antenna" shown in the upper right image.

      @jcorbella You will need:

      a separate power supply rated for the pump a small relay or mosfet to switch the pump to help isolate the pump motor from the ESP32 circuitry all grounds connected to a "common" no power interconnections, I.e. power isolated between LilyGO and pump power supply

      You can heat it with a hair dryer to melt the glue a bit. This allows easy removal of the screen structure without damage.

      Hi! This site is mostly user supported, I am a user.
      China was on holidays last week, so they may be "catching up"
      This email sales@lilygo.cc got an immediate response and they were sincerely interested and helpful.
