BitMaker-hub/NerdMiner_v2
Improved version of first ESP32 NerdMiner
NerdMiner_v2 is firmware for ESP32 boards that implements the Stratum protocol to attempt solo Bitcoin mining — not as a serious mining operation, but as a learning project and desk gadget. Your odds of finding a block are astronomically low (think lottery ticket, except the ticket costs $20 and some electricity), and the project is honest about this. It's for people who want to understand how Bitcoin mining actually works by running it on hardware they can touch.
The board support list is genuinely impressive — 20+ ESP32 variants covered, with PlatformIO build system and pre-compiled binaries for each. The multicore implementation uses both ESP32 cores for hashing while offloading Stratum/WiFi work to separate threads, which is the right approach for this hardware. Configuration via WiFi captive portal (no cable needed after flashing) is a good UX choice for a device that lives on a desk. The midstate SHA256 optimization is there, which shows someone understood the Bitcoin mining protocol at the implementation level rather than just wiring up a library.
The SLS directory is a massive blob of SquareLine Studio UI files and binary assets checked directly into the repo, which makes clones slow and git history nearly useless for those files. The online flasher at bitronics.store is a dependency on a third-party commercial site that could disappear — if you can't compile yourself and that site goes down, you're stuck. The 'In process' todo list includes BM1397 ASIC support, which has been sitting there long enough to look aspirational rather than planned. Security-wise, the default WiFi AP password is 'MineYourCoins' hardcoded in the README with no strong prompt to change it, so anyone nearby can reconfigure your miner's wallet address.
