The NerdOCTAXEγ is a 8-Asic version of the NerdQAxe++ with Nerdminer / Nerdaxe Display and is running the BitAxe Firmware as its Core.
It runs standalone and uses 8 ASICs of type BM1370 to achieve a Hashrate of ~9,5-10,5Th/s at about 160Watt + PSU (measured about 175Watts on wall with meanwell PSU)
Highlights:
- uses the NerdAxe / NerdMiner display
- 4-Phase Buck
- Standalone, no Raspberry Pi or other PC needed
- AxeOS with improvements and enhancements - slightly modified version of ESP-Miner-NerdQAxe+
- Influx DB support
- Better charting (10m, 1h, 1d), data doesn't get lost on Web UI reloads
- ASIC clock and voltage adjustable without reboot
The NerdOCTAXEγ runs with a modified version of the AxeOS: ESP-Miner-NerdQAxe+ (Releases for NerdOCTAXE-Gamma)
DISCLAIMER: This device is an highly advanced build and partly WIP. To get 8 Asics and the voltage regulator soldered properly can be very hard and frustrating if you are not used to soldering Asics or soldering in general. Using that amount of power, this device isn't a toy and you should know what you are doing - stay safe!
PCB: For example with the JLC Plugin for Kicad you can export the files out of Kicad to order directly from JLCPCB or any other PCB-Manufacturer
BOM: You can directly upload the .csv in this repo to Digikey (watch out - this is still a bit of WIP - you could delete the heatsink for example, which is actually in the BOM, but I am currently testing other ones which I will add later on). You will have to order the Lilygo T-Display S3 seperately.
HEATSINKS: Cooling is always a bit WIP. For the Asics I used the Heatsinks for "Fujitsu Primergy RX2540 M1 M2"
FANS: 2x Arctic S8038-7K (Monsters :P). I am currently running this miner with Fan-PWM set to 55%. This is enough to keep the buck at about 60°C and heatsinktemp at about 40°C.
CASE I used a 80x160mm Aluminium-Case which can be found in various lengths on Amazon/ebay/aliexpress etc.
BACKPLATE Step files will be provided soon. Will make some changes to integrate the T-Display better into the Backplate :) I used these XT60 Terminals integrated in the Backplate.
10/14/24: Changed the 4-Layer PCB to 6-Layer to conquer the heavy load on the rather small 1V2-Zone and added a whole 1V2 Layer + GND Layer. This should reduce the PCB-Temperatures, the Buck Temperature as it is located near the "hot" area and the voltage drop between the buck and the Asic Input. This design should be a little more energy efficient - I guess just some %´s, but should be noticable.
02/03/25: Current tested and working design is located in the "LED"-Branch. Refined design "Rev 2.0"-Branch is WIP and not tested yet. Will update as soon as I made the build!
03/04/25: First test of a open-PCB version of the NerdOCTAXE was succesful. Take a look into the LGA_Design-Branch :)
