You’ll need Linux and host mode USB for that to work — both a long shot for the ESP32. I think there is another ESP32 variant that has an Ethernet MAC, so that would be an easier place to start. There is a company called Olimex that make some ESP32 Ethernet dev boards (PoE too, I think). That would be a reasonable place to start.
PoE+ miners would be insane! :~)

I dont like wifi due to health issues, You can atleast have a V2 or USB type C so that users can buy their own ethernet to usb type c adapter.
I can understand that, and I am thinking the same way. There is a development kit for the esp with phy but you have still the firmware and tcp stack from the vendor, with all the "goodies". Anyway, there is a fork of the bitaxeultra named Pi-axe. I pointed that allready out here in the german section: https://bitcointalk.org/index.php?topic=5464963.msg63279811#msg63279811The design is as a "hat" for the Raspberry-Pi and you use the Pi Network, LAN or WiFi for comunication and it runs under a normal Linux. The User Mampf of the electronic forum mikrocontroller.net has made this as a hat for the Raspberry-Pi and provided the files for it in github: Pi-axe Hardware: https://github.com/shufps/piaxeMiner software in python for the Raspberry-Pi: https://github.com/shufps/piaxeThe original thread is in german, but you can of corse write in english there: https://www.mikrocontroller.net/topic/561921#new

Health issues? Due to electromagnetic radiation? Because you're exposed to that 24/7 no matter if you turn off your WiFi or not. Think: HF radio, amateur radio, cellular radio, police radio, other people's WiFi networks, and the list goes on. Walk around your home with a software defined radio and check out how much is going on across the whole frequency range..

feedback: please make a ethernet vesion. Due to privacy and security issues, i dont use wifi. Hope the bitaxe HEX makes it or atleast has a USB Type C so one can use a ethernet to type C adapter.
The ESP32-S3 we use in the bitaxe does not have a Ethernet MAC, so this is not an easy change. What sort of privacy and security issues do you have with WiFi? Great project, inline with the Bitcoin spirit! Skot, did you try to use a PWM pin connected to an RC filter, can even be two stages of RC filtering, to get rid of the DAC IC? Let me know if I can help.

Hi Has anyone tried using a voltage value of 1300mv for a few months? could it be exaggerated or dangerous for a long time? Thank you

I don't own the BitaxeUltra, but having worked with similar chips on stick and pod miners in the past, it's generally safe to run any voltage, as long as the chips stay cool enough. In some cases, industrial miners run their chips at substantially higher voltages than the ranges we use on micro-miners, even when using the exact same chips, simply because they have better cooling solutions like high-flow, high-pressure - but very loud - industrial fans, or liquid cooling setups. Do keep in mind that there's a point where your efficiency starts to decrease, simply because the increased power draw from the higher voltage stops yielding substantial improvements in stable clock speed (and thus maximum hashpower), so keep an eye on that as well.

I'm reverting back to the V2.0.4 firmware.
I updated one of them to V2.0.7 and was getting reboots every 4-10 hours.
Stock settings so lets see if this is a firmware or hardware issue.

At the moment I have no problem with the 2.07 firmware. Reverting back is possible with the normal website from the miner? Or do you flash the miner per USB? Just interested to be prepared if I have also step back to a older firmware. Best regards, Willi

Cannot address the exact problem but getting reboots in the same time frame or the hashrate is decreasing to 0TH/s and is stuck until I do a manual reboot. Will flash back to an older version and will monitor it.

You guys make sure to report an issue here: https://github.com/skot/ESP-Miner/issuesIt's much more likely for the maintainers of the firmware to see it there. Do include as many details as you can (e.g. after how much time exactly something happens, what happens, ...) to help them get it fixed.

Yes you can revert back from miners UI / Website. For me V2.0.4 seems to be more stable. You guys make sure to report an issue here: https://github.com/skot/ESP-Miner/issuesIt's much more likely for the maintainers of the firmware to see it there. Do include as many details as you can (e.g. after how much time exactly something happens, what happens, ...) to help them get it fixed. Submitted the bug and added an enhancement request to add suggest difficulty to the UI to help expedite the miner finding its sweet spot on pools.

Yeap you can check on github: https://github.com/skot/bitaxe/tree/ultra?tab=readme-ov-file#bm1366BM1366 -The BM1366 is a undocumented SHA256 mining ASIC from Bitmain. It's mostly used in the Antminer S19XP -Bitmain claims the BM1366 has 0.021J/GH efficiency -The BM1366 is available (new) for around $15 each in small quantities. -The BM1366 has a different footprint and pinout from the BM1397 and BM1387 in previous bitaxe. -The BM1366 appears to roll more than just the nonce on the chip. This is great news, because it allows much longer serial chains of ASICs and new work doesn't need to be sent as often.

Yeah but I am near an Air Force base which routinely knocks out my wifi for 20 or 30 minutes at a time. I would want to run a few of these with an eth cable.

Like, knocked out from RF interference? That's wild. It would be a big job to add ethernet to the Bitaxe. It's built for WiFi from the ground up. I wonder what would happen if you directly connected the ESP32 wifi to a wifi router with coax... Espressif makes a drop-in ESP32-S3 variant with a u.fl antenna connector. I assume some attenuation would be necessary.
