Let me start with I'm watching this for sure! I've got a few remarks after looking at the schematics. I presume you've got the bm1366's connections from tracing the signals on a hash board and not from an 'official'…
Version rolling is not possible with most (stratum V1) pools; the ticket send back to the pool does not include nversion. ntime is no problem though, but you 'only' gain 60x with that, so you will only have to send work…
That's about the block generation on the controller, and that's not hard to do even on tiny hardware (to be more specific regarding the esp32-c3; its a single core that also has to do the wireless comms, and the time…
"irrelevant" is badly chosen. I mean it is unavoidable to always have to send work updates, whereas tickets posted by the miner can be avoided by choosing a high difficulty. I'm no pool operator (obviously), but keeping…
My goal would be to bring the pcb to market and let the end user fiddle with the cooling. Cooling will not be hard as the asic is the sole component on the side of the pcb it is mounted on, so different size heatsinks…
Yes, 15W max as that is the maximum power a usb charger can handle @5V. The miner in the screenshot consumes ~13W from the wall, the efficiency of the charger is 87%, so the miner itself uses ~11.3W at ~250GHs. You've…
The big difference is that the Compac F needs a computer attached to it to run as it uses cgminer software that requires hefty hardware to run on. My miners are standalone and require no computer. Some links to my…
I'm working on a line of standalone miners that use BM1387 and BM1397 ASICs, plus an ESP32-C3. It's been over a year in the making, and I feel ready to create a version for mass production. So, is there actually any…

I did not look at your schematics, but you can (and should if you want to save cost) use Vcore for 1.2V. I have all my miners converted to 1.2V this way. Also you can make the 0.8V with a simple resistor divider from…
