NerdMiner V2 Desktop Bitcoin Solo Lottery Miner
Plug-and-Play ESP32 Crypto Dashboard & Micro-Miner (ESP32-2432S028R)
The NMMiner NerdMiner V2 is a compact, plug-and-play desktop Bitcoin lottery miner and crypto dashboard built directly on the popular ESP32-2432S028R ("Cheap Yellow Display") development board. Driven by a dual-core ESP-WROOM-32 processor, this device comes pre-flashed with open-source NerdMiner firmware to perform low-power SHA-256 solo Bitcoin mining over 2.4 GHz Wi-Fi. While its average hash rate of ~960 KH/s makes finding a valid block statistically equivalent to winning a national lottery, it serves as an engaging, low-energy (~1W) educational tool and real-time crypto monitor for Bitcoin enthusiasts.
Beyond its mining functionality, the device features a bright 2.8-inch 240x320 TFT display with resistive touch capabilities to render dynamic graphical dashboards. Users can switch between visual screens displaying real-time hash rates, total submitted shares, current Bitcoin market prices, block heights, and network difficulty without requiring an external computer. Equipped with an onboard MicroSD slot, custom light sensor, and USB-C power delivery, the NMMiner combines functionality and novelty into a sleek desktop crypto display right out of the box.
