Other key parts include the BM1368_MODE1, TPS53647, CSD95472Q5MC, AP3211 and MCP1824T-0802E. By type, the board carries 206 capacitors, 51 resistors, 22 ICs, 4 inductors, 3 diodes and 2 modules.
From the project
Miner with 8 Asics based on the NerdQaxe+
The NerdOCTAXE+ 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 BM1368 to achieve an average Hashrate of ~5Th/s at ~100Watts (approx. 110Watt at the wall... i have not measured it yet)
- uses the NerdAxe / NerdMiner display - 3-Phase Buck // The TPS could handle 4 Phases... currently thinking of changing it to 4-Phase design - Standalone, no Raspberry Pi or other PC needed - AxeOS with improvements and enhancements - slightly modified version of ESP-Miner-NerdQAxe+ - Influx DB…
