FREENOVE Bitcoin Miner Solo Lottery Miner - ESP32 Dual-Core - 3.5-inch Touch Display - Wi-Fi + BT

Overview

Meet the Freenove Bitcoin Miner Solo Lottery Miner, a compact, hobby‑friendly device designed for hands‑on exploration of mining concepts. It can operate as a complete miner once the setup is completed and the miner software is installed or upgraded. You only need USB power and a Wi‑Fi connection to get started, and a smartphone helps with the initial configuration while a computer can assist with software installation and upgrades. Note that the miner software may not be pre‑installed, and you may need to update to access the latest features.

Compact hardware with room to grow

The onboard ESP32 module is a dual‑core 32‑bit processor capable of up to 240 MHz, paired with 4 MB flash, 520 KB SRAM and 448 KB ROM. It includes 2.4 GHz Wi‑Fi and Bluetooth 4.2 LE, providing convenient wireless access to your network and nearby devices.

• Dual‑core ESP32 for responsive UI and local processing
• Wi‑Fi and Bluetooth for wireless setup and control
• Generous flash and RAM for future software upgrades

Onboard display for at‑a‑glance status

The 3.5‑inch TN TFT screen with 320×480 resolution and an ST7796 driver shows app states, progress bars, and alerts. It uses a single‑point resistive touch, which may require a bit more pressure to recognize input; if needed, use the included stylus or a fingernail for reliability.

Versatile ports and ease of expansion

Multiple interfaces invite experimentation and growth. You’ll find a memory card slot, USB‑C, serial, SPI, I2C, input pins, a speaker, a battery port, a RGB LED, and BOOT/RESET keys—plus several GPIO options for DIY tweaks.

• Memory card slot for data and logs
• USB‑C, serial, SPI, and I2C for broad connectivity
• Dedicated pins and indicators to help with debugging and customization

Guided learning and ready‑to‑run code

The package includes example projects aligned with ESP32 and the LVGL GUI library. A tutorial link is printed on the product box to guide you through setup and basic code workflows, helping you get up to speed quickly even if you’re new to microcontrollers.

Practical use cases

• Desk‑side mining experiments and learning how hardware interacts with network software
• Prototype IoT projects using the ESP32 module and LVGL GUI library
• Hands‑on troubleshooting and upgrades with a compact, self-contained device

What’s included and what you’ll need

What you receive includes the display, ESP32 module, and essential connectors. You’ll typically need a computer for software installation and a phone for initial Wi‑Fi configuration. A straightforward setup path helps you begin exploring flexibly.
