It ships with example code and a link to online tutorials; note that miner software may need installation or upgrading on a computer to reach the higher reported hashing rates. The device requires USB power and Wi‑Fi to run miner software, and a smartphone is recommended for the first setup step.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the miner function and what setup is required?\u003c\/h3\u003e\n\n\u003cp\u003eThe miner runs on the onboard ESP32 module and uses Wi‑Fi for network connectivity; it can operate as a complete solo lottery miner after software is installed. First‑time setup typically uses a smartphone to join the device to your network; upgrading or installing miner software is done from a computer when higher performance is desired.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eRequires USB‑C power and 2.4 GHz Wi‑Fi to operate.\u003c\/li\u003e\n  \u003cli\u003eSmartphone simplifies initial configuration; computer needed for software upgrades.\u003c\/li\u003e\n  \u003cli\u003eMiner software may not be preinstalled; tutorials and code examples are provided online.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat hardware and connectivity options are available on the board?\u003c\/h3\u003e\n\n\u003cp\u003eThe FREENOVE unit integrates an ESP32 (dual‑core, 240 MHz) with 4 MB flash and multiple ports for expansion.
