Hi, The description includes:

"Add one I2C bus expansion interface and one UART expansion interface for customer DIY use".

What are these PINs? Where can I find these. I need these PINs to connect an ESP8266. Thanks.

You can find them in the AUX-2 connector

Thanks a lot ! Is this motherboard suitable for Ender-3 PRO? The hot bed (24V / 220W / 2.6 ohm / 9.2A). The AUX-2 connector SDA0 SCL0 pins what outlets ?

The board is named E3 as Ender3. The screw holes are spaced the same as Ender3

Hi, Can I use "#define SERIAL_PORT_2 3" in Marlin?

radek8 commented 2 years ago

No. You use

define SERIAL_PORT_2 2

In the processor specification, pins P0.10 and P0.11 are listed as Uart2 I wrote it at the beginning of the ticket

You can also use UATR0 But then you will have nowhere to connect the touch screen

The index for the letters RT and TX indicates the serial port number that you must define in Marlin. RX2, TX2 set port 2 in Marlin RX0, TX0 set port 0 in marlin
