FREENOVE ESP32 Bitcoin Solo Lottery Miner with 2.8" Touch

The FREENOVE Bitcoin Miner Solo Lottery Miner is a compact, programmable ESP32 device with a 2.8" touch display that can run solo-mining software when supplied with USB power and Wi‑Fi.

This pocket-sized unit combines an ESP32 dual-core microcontroller with a 240x320 TN touch screen, multiple I/O ports and a suite of example projects so makers can tinker with mining, IoT and graphical interfaces. It ships with a resistive stylus, onboard peripherals (speaker, RGB LED, card slot) and code tutorials available online, enabling both beginners and experienced developers to prototype display-driven applications or experiment with Bitcoin solo-lottery mining after installing or upgrading miner software.

How do I get the miner running for the first time?

Initial setup requires USB power and a smartphone for the guided Wi‑Fi pairing; miner software may need to be installed or upgraded from a computer. FREENOVE provides an online tutorial and code samples to walk you through flashing firmware and configuring the solo-lottery miner.

• Power via USB‑C and connect to 2.4 GHz Wi‑Fi
• Use smartphone for first-time network setup
• Download miner binary or upgrade tools on a PC when required
• Follow FREENOVE online tutorial for step-by-step instructions

What hardware and ports are included for projects and extensions?

The board integrates an ESP32 microcontroller (dual-core, 240 MHz) with 4 MB flash and multiple external connections for peripherals and expansion. You’ll find a memory card slot, serial and SPI ports, input pins, speaker port, battery connector and BOOT/RESET buttons to support a wide variety of maker projects.

• ESP32: dual-core 32‑bit up to 240 MHz with Wi‑Fi and Bluetooth 4.2
• USB‑C power and serial programming port
• SPI, general input pin header and serial interfaces for sensors
• MicroSD slot, speaker port and battery port for portable builds

How does the 2.8" touch display perform for UI and graphics?

The device uses a 2.8" TN TFT with 240×320 pixels driven by an ST7789 controller and a single-point resistive touch panel. It works well for simple GUIs and LVGL-based demos provided in the examples; note resistive touch requires pressure, so use the included stylus or a fingernail for best response.

• 240×320 pixel ST7789-driven TN TFT for clear icons and text
• Single-point resistive touch; stylus included for accurate input
• Compatible with LVGL GUI examples from FREENOVE
• SPI communication minimizes wiring for displays in projects

Can I use this for learning ESP32 programming beyond mining?

Yes—FREENOVE bundles example projects and LVGL GUI demos so you can learn ESP32 peripherals, display control, Wi‑Fi and Bluetooth features, and how to structure embedded applications. The kit is well suited for experimenting with IoT dashboards, media playback via the speaker port, or portable battery-powered prototypes.

• Example code for ESP32 peripherals and LVGL graphical interfaces
• Bluetooth and Wi‑Fi examples for connectivity experiments
• GPIO and SPI ports enable sensor and actuator integration
• MicroSD and speaker support for multimedia or data logging

Who is this for? Makers, educators and hobbyist developers who want a small, display-equipped ESP32 development platform that can also be used to experiment with Bitcoin solo-lottery mining. If you like hands-on setup, flashing firmware and customizing code, this unit provides the hardware and online tutorials to learn embedded graphics, connectivity and mining software—while keeping power and size minimal. It’s not an out-of-the-box high‑rate mining appliance; expect to install or upgrade miner software and follow the provided guides to reach intended hashing performance.
