NerdMiner v2 - Mining Bitcoin on a Tiny ESP32

NerdMiner is an open-source Bitcoin solo-miner built on a small ESP32 microcontroller with Wi-Fi. 

It has a low hashrate of about 56 kH/s, so you won’t earn profit from it—but that’s not the goal. NerdMiner is made for learning, experimenting, and having fun. It’s like a geeky, interactive gadget for your desk.

The device costs around 15 euros and only uses about 1 watt of power, which makes it super affordable and energy efficient.
It connects to mining pools and shows real-time mining stats on a small OLED screen—like hashrate, accepted shares, and more.

Even though it’s not powerful, it’s a great way to understand how Bitcoin mining works without needing expensive hardware. Ideal for tech lovers, students, or anyone curious about crypto and microcontrollers.
