Finally arrived.
Some issue with fitment. Thanks to plastic enclosure you just need to push it harder. Acceptable result for development with no enclosure on hands.

TS now can read livedata from 1f_rev2 wideband.
Next step is settings.

PS communication is over UART 115200. Next step is CAN.

DAC output works! Next step to merge the DAC code into official repo and fix PCB dimentions.

It's getting really interesting. Unfortunately I have 5 boards to assembly with rev2. But you are already in rev3 :lol:.

I think I will wait until the things be more stable. Also the stm32 mcu seems be out of stock. On this board do you use a Chinese version?

stm32/gd32 questions is now clarified on https://github.com/rusefi/rusefi-hardware/blob/main/wideband-F103/readme.md my boards are a mix depending on what was available at time of order.

Also added a link to rev2 firmware binaries.

At the moment I am not sure if I will be ordering rev 4 on Tuesday or much later, overall this F103 is very much in the air.

I have bought today two gd32f103. I will assembly the rev0.2 to see if works properly. I have also with me two ch32f103 do you think that will be possible make this one works also?

No plans for ch32f103 sorry, each extra chip is huge amount of effort.

Will take time to receive the GD32. I have have spare boards let's see if I can make CH32 works :lol:

Nissan uses 4 wire "middle band" sensors, do these have anything in common with our WBO logic?

Nope, they're basically just "source voltage and measure current" type devices, no active control really needed.

@Dron_Gu: Which enclosure is this? It looks very nice :)
Thank you!

But with slight modification (planned for V2) should also fit into https://aliexpress.ru/item/4000811747039.html

Stock ECU
hard wired to battery
quick engine restarts seem to have a problem:
on engine cranking controller seems to go into heating mode where it takes a while to re-heat what is supposed to be a hot sensor

Re: F103 Wideband Controller

Battery voltage drops down to 8.53V (actually seems even lower) during cranking. This cause controller to switch to SensorNoHeatSupply state and after battery voltage rises above 9.5 - start heating from the beginning.

 LSU adv five wire pinout
Something like 2017-2019 Audi A4 Upstream Front Oxygen Lambda Sensor 8R0906262 8R0906262E would be the sensor
