EDIT: At 550/1250, I get 28.3 W at the wall and 27.3 W in AxeOS
I provide only 120V AC input to the PSU, making it even less efficient.

At 550/1250, fan fixed at 80% my LV07 hashrate is 1050GH/s, Asic temp is 55C, VR temp =51C, gui says 26.9 Watt, AC measured is 28.6 Watt
At 600/1200, fan fixed at 80% my LV07 hashrate is 1120GH/s, Asic temp is 55C, VR temp= 52C, gui says 26.9 Watt, AC measured is 28.5 Watt
Same power consumption but just over 6% more hash capacity.
Asic lottery ..
Worth checking out what each LV07's individual sweet spot is.
Thank for feedback, Today i hook it up to a mw psu and do some tests.
I modded the fan system, machined the heatsisnk and replace the thermal grease, designed new panels for mounting noctua fans now im getting asic temp to 38c and vr 33c. Maybe my asics are tired.

Edit: confirm there are 5/6w of difference between axeos and smart plug (tried 3 different kinds) maybe a small sw bug.  The discrepancy get larger ( over 10w) with custom overclock.  

23w > 29w (meanwell psu) using default values.

edit: just flashed via uart. all good, thank you!

Well done! And thanks for the feedback on your success!

Hi and thanks, I modded the box a little with a better fan and new thermal grease: ASIC temp 39°C / VR 33°C. Your firmware has been running smoothly for many hours without a single issue, 550 MHz / 12.5 V ~ 1.05 TH on average.

I only see a significant discrepancy between my smart plug and Axeos power monitor. The smart plug (which I know is accurate) reports that the miner is drawing 27 W at the wall, while the dashboard only shows 22.5 W. I guess this difference is due to PSU efficiency, with the extra power likely dissipated as heat.

Would it be useful to have an estimated real power draw on the dashboard?
Something like:
Power 22.5 W (-10/15% (editable) PSU efficiency: 4.5 W = 27 W)
assuming one is using the stock power supply?

Thanks for your work!

Would anyone lay down a schema of the pins? there are 6 and not sure which one to use.

The pins are labeled on the back of the board, see the picture in the top left corner.



Connect the ground of the adapter to the GND of the ESP pin. Then connect adapter TX with P_RX and adapter RX with P_TX crosswise.

To make the ESP32 flashable, you must switch to boot mode: Connect GPIO0 (IO0 on the LV07) on the ESP32 to ground (GND on the LV07). Then press the reset button on the back of the LV07 with a paper clip. Only then disconnect the ground from GPIO0.


Thank you so much, i mean they are in order like this:

io0 - rx
gnd - tx
3v3 - en (last square pin)
(in the order of flipped image)

as for boot mode, i keep rx-tx attached then swap from io0 to gnd after clicking the switch?

Correct?

Greetings, i have been reading this for a while, i want to flash my lv07, i dont have the clamp so im gonna solder pins use wires to hook up my uart adapter.
Would anyone lay down a schema of the pins? there are 6 and not sure which one to use.
Thanks for the great work that has been done, and tia!
