The NM-RF-Hat
Main Features
1. Hardware-Level Conflict Resolution: The RF Switch Breakthrough：
• The Problem Solved: The notorious SPI bus conflict when integrating multiple modules (CC1101, SD Card, Display) is over. We’ve implemented a Hardware RF Switch that allows you to seamlessly toggle between RF modules.
• Plug-and-Play Stability: No more firmware hacks or complex pin remapping. Simply flip the switch to ensure stable, reliable operation across all integrated components.
• Minimal Wiring: Designed for simple connection to the ESP32-2432S028 (CYD) via a few dedicated lines ( 2x4Pin Cable, 1x5Pin Cable, 1xTF male Extension Cable), turning a complex DIY project into a clean, modular assembly.
2. Maximum Integration: All-in-One RF & Utility： This single PCB integrates every critical module the Bruce community demands, making it the most feature-complete companion board available:
Module Frequency/Type Function Sub-GHz CC1101 (433MHz) Remote Control, Sensor Capture 2.4GHz nRF24 Wireless Protocol Analysis NFC/RFID PN532 Read, Write, Emulation IR Control IR TX/RX Infrared Signal Capture/Replay RF433 OOK TX/RX Basic RF Transmission Power Mgmt USB-C, BAT Circuit Charging, On/Off Switch Expansion GNSS Header GPS/Location Tracking If you have CYD (ESP32-2432S028) already, only need to flash Bruce-CYD-2USB firmware.
3.NM-RF-HAT GPS Module | Plug & Play：
This NM-RF-HAT new version GPS module features a true plug-and-play design with no drivers or complicated setup required.
It delivers fast satellite acquisition, high sensitivity, and stable positioning even in weak signal environments. Compact and widely compatible with development boards, IoT devices, robotics, and vehicle tracking applications, this module offers strong anti-interference performance and low power consumption for reliable long-term use.

Where to get the NMMiner firmware?
To get the firmware,
- you can get it from NMTech’s github.
- you can flash the NMMiner firmware to your device from the NMMiner web-flash-tool.
- Web Flash Tool: https://flash.nmminer.com
If you accidentally lose your license or flashed other applications, the web flash tool will help you find and recover it (do not need any fees). So don’t worry to erase the board for other applications, you can reflash the NMMiner, and there’s no need any activation. If you don’t have a license yet, you can directly jump to the activation page from the web flash tool. The nm-bot-chain, nm-usb-chain, Heltec Vision Master T190 (NMMiner) , CYD-NM, NM-TV-154, are NMMiner Inside devices, no longer need to activate.
How to config the NMMiner easily?
With the NMMiner web-flash-tool, https://flash.nmminer.com, you can config the NMMiner more easily.
Update the firmware
Step 1: When you first get the device, you should choose the device type you have, choose it and Connect and Program.
Step 2: When the NMMiner works well, you can see the WiFi and BTC address configure input box Input your WiFi SSlD and password, BTC address, config the device. lf everything is ok, you can see the Hashrate report from the Console.
Console Only
If you don’t need to update the firmware, just check the Console only, the NMMiner will run, then you can config it as【Update the firmware】 Step 2.
NMController Cluster Management Tools
- NMController_client, source code, we put the *_x64.msi and *_x86.msi in tool folder already, just install, only for Windows
- NMController_web, source code, it’s a Python implement, for Windows and Mac.
How to manage my NMMiners?
if you have many NMMiner devices, you can use the Controller software provided by NMTech tomanage all devices within the LAN(local area network), currently support all NMMiners and NMAxe.
You can get this tool from github: https://github.com/NMminer1024/NMMiner/tree/main/tool.
- nmcontroller client, only support the windows system, and maybe you need download the .Netframework.
- nmcontroller web, https://github.com/NMminer1024/NMController web, you just need a pythonenvironment to run it,python nmcontroller.py.
With the NMController, you can quickly enter the device management page.
