2 PACK 2.8inch ESP32 Solo Miner LCD Display Cryptocurrency Solo Miner¶
Description¶
2.8 inch BTC Miner with Cheap Yellow Display(CYD)
This ESP32 2.8-inch display module is a HMI (Human Machine Interface) touchscreen designed specifically for mining rigs, featuring a 320*240 resolution LCD screen. It uses the ESP32-WROOM-32 module as the main control processor, equipped with a dual-core LX6 microprocessor with a clock speed of up to 240MHz. Highly compatible with NMMiner Official software, it's ready to use immediately after flashing, with deeply optimized firmware that significantly boosts mining hashrate to 1000KH/s. Integrated Wi-Fi and Bluetooth functionality support independent 2.4G WiFi mining, eliminating the need for an external computer and allowing for convenient operation via Bluetooth and WiFi.
The CYD uses resistive touch technology and comes with a resistive pen. For expanded functionality, the board includes a TF card slot, multiple peripheral/I/O ports, a USB (TTL converter) port, a USB-C interface, a speaker port, and a battery port, providing greater expansion possibilities. It supports development environments such as Arduino IDE, Espressif IDF, Lua RTOS, and Micro Python, and is compatible with the LVGL graphics library. It also supports openHASP, providing an efficient and reliable solution for cryptocurrency mining.
Besides mining, the 2.8-inch display can also be used in smart furniture control panels, industrial control systems, medical device interfaces, and other IoT applications, offering a comprehensive and reliable display solution.
