ESP32 2.8" Touch Screen Development Board Kit, WiFi ESP32-2432S028R for Programming Learning, IoT Projects & Desktop Tech Display DIY Projects

Introducing the RCmall Heltec NerdMiner V2, a compact Bitcoin mining device featuring a vibrant 2.8-inch display for real-time monitoring of your mining operations. This DIY kit comes with the ESP32-2432S028R module at its core, capable of achieving hash rates up to 377KH/s. The kit includes everything needed for assembly: a pre-programmed control board, mounting hardware, connection cables, and a protective case with precise cutouts for optimal functionality. The built-in LCD screen provides clear visibility of mining statistics, network status, and WiFi configuration options. Perfect for cryptocurrency enthusiasts looking to explore Bitcoin mining or those interested in learning about blockchain technology through hands-on experience. The device offers a user-friendly interface and comes with detailed assembly instructions. Note that some technical knowledge may be required for setup and configuration. This educational mining tool combines practical functionality with an interactive learning experience, making it ideal for both beginners and experienced crypto enthusiasts. Specially optimized algorithm firmware enhances the hashrate to 410KH/s, increasing the probability of winning the lottery by 420% (Nerdminer v2 only 55KH/s). The display will turn off after 1 minute without operation, and you can wake up the screen by pressing any key to avoid light pollution. We offer long-term support for our services, https://t.me/NMMiner. By double-clicking the USER key, allows you to switch to a desktop clock mode with the BTC Lottery runs in the background.
