Other key parts include the CSD95472Q5MC, BM1370_MODE1, TPS53667, AP3211 and MCP1824T-0802E. By type, the board carries 331 capacitors, 63 resistors, 30 ICs, 15 inductors, 3 diodes and 2 modules.
From the project
8-Asic Miner based on the NerdQaxe
Rev3.4: - 6 Phase Buck Converter - Added curcuit to read the internal temperature of each asic
The NerdOCTAXEγ runs with a modified version of the AxeOS: ESP-Miner-NerdQAxe+ (Releases for NerdOCTAXE-Gamma)
To flash the Lilygo T-Display you can use the Webflasher
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! Also…
