FREENOVE ESP32 Bitcoin Solo Lottery Miner 2.8" Touch

The FREENOVE Bitcoin Miner Solo Lottery Miner is a compact, programmable ESP32‑based device with a 2.8" touch display that runs hobbyist bitcoin mining software and hands‑on ESP32 projects.

This pocket‑sized unit combines a dual‑core ESP32 microcontroller, a 240×320 TN touch screen, and a set of I/O ports so makers can experiment with mining software, graphical user interfaces, and embedded projects. 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.

How does the miner function and what setup is required?

The 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.

• Requires USB‑C power and 2.4 GHz Wi‑Fi to operate.
• Smartphone simplifies initial configuration; computer needed for software upgrades.
• Miner software may not be preinstalled; tutorials and code examples are provided online.

What hardware and connectivity options are available on the board?

The FREENOVE unit integrates an ESP32 (dual‑core, 240 MHz) with 4 MB flash and multiple ports for expansion. You’ll find a microSD slot, serial and SPI headers, an input pin connector, speaker port, battery connector, RGB LED and convenient BOOT/RESET buttons for development and troubleshooting.

• ESP32 with Wi‑Fi and Bluetooth 4.2 (LE) for wireless projects.
• USB‑C port for power and possible data connections.
• SPI, serial, input pins and microSD for peripherals and storage.

How is the 2.8" screen and touch interface used for projects?

The included 2.8" TN display with ILI9341 driver provides a 240×320 pixel canvas for GUIs and status displays. The screen uses a single‑point resistive touch layer—this works well with a stylus or fingernail and enables LVGL‑based graphical interfaces shown in the sample projects.

• ILI9341 driver, 4‑wire SPI communication for efficient drawing.
• Resistive touch requires firmer pressure—stylus included for accuracy.
• Compatible with example LVGL GUI code for quick interface prototypes.

What kind of code and tutorials are included or available?

FREENOVE supplies online example projects for ESP32 development and LVGL GUI demonstrations; a tutorial link appears on the product box. The examples help you run miner software, build custom displays, or connect peripherals; community and manufacturer resources cover flashing firmware and debugging.

• Example ESP32 projects and LVGL GUI demos included online.
• Tutorial link printed on the box—no paper manual inside.
• Community guides useful for installing or upgrading miner software.

Who is this for: The FREENOVE Bitcoin Miner Solo Lottery Miner is aimed at makers, hobbyists, and developers who want a compact ESP32 platform that doubles as a learning‑friendly bitcoin lottery miner. It’s suitable for people comfortable flashing firmware and following online tutorials, and for anyone who wants a small touchscreen device to prototype IoT, GUI, or lightweight mining experiments rather than a plug‑and‑play, high‑performance ASIC miner.
