PCB Design for Bitcoin Mining

flux

I can’t continue editing the project right now because execution credits are unavailable.
Current project state:
  • The project is still empty: 0 components and 0 nets.
  • No schematic, layout, or documentation has been created yet.
  • The project still has the placeholder name “Peaceful Chocolate Interocitor.”
What remains to design:
  • Define the mining architecture: ESP32 controller + Bitcoin mining ASIC + power system.
  • Select a real SHA-256 mining ASIC that is available and documented.
  • Add ESP32, ASIC support circuitry, oscillator/clocking, programming interface, and boot components.
  • Add display interface, likely I2C/SPI OLED or TFT.
  • Add fan connector and fan power/control circuitry.
  • Add main power connector sized for ASIC current.
  • Design regulators for ESP32, ASIC core voltage, I/O rails, and fan rail.
  • Add thermal protections, current sensing, fusing, and decoupling.
  • Verify the ASIC datasheet wiring and run schematic review.
  • Create PCB placement with ASIC thermal copper/heatsink/fan airflow considered.
  • Route power carefully with wide copper pours, short high-current paths, and proper grounding.
Important design note: a Bitcoin mining ASIC is not like a normal microcontroller peripheral. It usually needs very high current at a low core voltage, careful clocking, heavy decoupling, thermal management, and often proprietary control protocols. Before building the schematic, we’ll need to choose the exact ASIC part/module and power target.
When credits are available, the first thing I’d do is gather requirements and select parts:
  1. Target hashrate or ASIC family.
  2. Input power source, e.g. 12 V barrel jack, ATX PCIe, USB-C PD.
  3. Display type and size.
  4. Fan voltage, probably 5 V or 12 V.
  5. Whether this is educational/low-power or intended to mine continuously.
