NMMiner Manuals & User Guides

NMMiner, also known as NMTech, specializes in the development of micro-mining hardware designed for Bitcoin solo mining. Utilizing the ESP32 series architecture (including Xtensa32 dual-core processors), NMMiner produces "lottery miners" that operate with minimal power consumption (typically 0.5–1W). These devices, such as the NM-CYD and various USB-stick form factors, allow users to participate in the Bitcoin network with a chance to mine a block solo, serving as both educational tools and entry-level crypto hardware.

The brand supports an active community of developers and hobbyists, offering open firmware and easy-to-use web flashing tools to optimize hash rates. NMMiner devices often feature integrated displays for real-time monitoring and support WiFi connectivity for seamless setup.

• How do I reset my NMMiner device?

  To reset the device, press the physical 'reset' button once. For a factory reset or to clear configuration status, you may need to long-press the 'boot' or 'user' button depending on the specific model (e.g., NM-CYD, NM-USB).

• How do I configure the WiFi on NMMiner?

  On first power-up, if the device cannot connect to a known network within 15 seconds, it will create a hotspot named 'nmap-2.4g'. Connect to this hotspot, and your browser should redirect to the configuration page (or visit 192.168.4.1 manually).

• What mining pools are supported by NMMiner?

  Due to limited chip resources, NMMiner works best with low-difficulty pools such as public-pool.io (port 21496) or pool.tazmining.ch (port 33333).

• How can I update the NMMiner firmware?

  You can update your device firmware using the web-based tool at flash.nmminer.com, which requires connecting your device to a computer via USB.
