Omega2 annotated pinout (including MT7688 pin names)
-
@luz What PCB did you design? Care to share?
-
@Victor-Tagayun it was a small mainboard hosting the Omega, a ethernet jack, a 4.5..39V to 3.3V converter (single part, integrated), a RS485 serial, two multiplexed i2c connectors and a level shifter for WS281x LED chains.
If anybody is interested in this very particular combination of features, just let me know
This is part of a larger project, which I will publish as soon as all the hard- and software parts work together as intended, from laser cut wood to WS281x kernel driver using MT7688 PWM…

I was looking at the wrong bootstrap-pin in the PDF earlier, UART0_TX should be pulled down, so the pull-down resistor doesn't matter. I was looking at the boostrap-pin on UART1_TX, which is the opposite.
Can I please ask what this PDF file is?

@György-Farkas A PDF-file is short for "portable document format" and is a file format used to present documents in a manner independent of application software, hardware, and operating systems. Each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, graphics, and other information needed to display it. -- https://en.wikipedia.org/wiki/Portable_Document_Format

Really?!

@György-Farkas The MT7688 specsheet, what else?

..., 998, 999, 1000
Thank you very much indeed.

Does someone knows if there is somewhere released the acutal Omega2 schematic? in the Github repository I just find the Omega(1) which mounts the Atheros and not the MT7688.

Not yet. Pls be patient.

Thanks mate! You just saved me a lot of debugging time
