Version chaos, USB Power Supply, Fan invertion, max temp BM1366

[TheRockaXXX]

Hello everybody,
i have a few question, i can't find a solution for. Thanks for your help.

1. I don´t understand the Versions: v2.1, v2.2, Bitaxe Ultra 201 or 202.... What is the secret and the differences between the Versions and where can i get the information about?
2. Is the USB C Port also usable for power supply the device?
3. Should the fan blow or suck? My default setting is "inverted" and the fan blows air. Seems to work, but that the normal setting?
4. What is the highest temperature with which the BM1366 should work? My average temperature is about 53 Grad Celsius.

I hope, you can help. Maybe i haven't found the right place to find the information. Where can i look it up?

Thank you very much!!!!

The master branch is the latest released version. It uses the BM1366 chip. Everything else is for development. If you want to be involved in that, you should check out the OSMU discord.

2. Is the USB C Port also usable for power supply the device?

USB will power up the bitaxe, but is inadequate for mining.

3. Should the fan blow or suck? My default setting is "inverted" and the fan blows air. Seems to work, but that the normal setting?

There is some debate about this. I prefer blow. The esp-miner "inverted" setting doesn't change the fan direction. It's for the PWM idle state.

4. What is the highest temperature with which the BM1366 should work? My average temperature is about 53 Grad Celsius.

53 is great. 60c is fine, I wouldn't go above 70c. There are no hard rules here.

I hope, you can help. Maybe i haven't found the right place to find the information. Where can i look it up?

We're a little light on documentation as everything is still work in progress. If you want to know the latest and greatest, you should check out the OSMU Discord; link on bitaxe.org

Thank you very much!!!!

I tried to join your discord https://discord.gg/pF9smpe3yE, but the invitation link is invalid. Is the server full?

Thanks!
