Rockbase Technology (Chengdu, China) is dedicated to making industrial IoT stable, secure, and scalable.

On GitHub, we share tools, libraries, and reference implementations that power our own products. We believe in the power of open source to accelerate innovation in the industrial space.

Here are some ideas to get you started:

• NM-CYD-C5

  Currently, we are collabrating with the NMTech Team to develop the Cheap Yellow Display development board which use the ESP32-C5 dual-band wifi (2.4G/5.8G WiFi). This board aims to be the world's first BTC lottery device which support dual-band WiFi. And it also will support opensource projects such as Bruce and Marauder. Of course, the nm-cyd-c5 will support the nm-rf-hat designed by NMTech Team.

• NM-RF-HAT

  Collabrate with NMTech Team, support the Normal Cheap Yellow Display 2.8 inch and the newest NM-CYD-C5 which use the ESP32-C5 dual-band wifi. Compatible with brucefw and Marauder projects.

• BruceDevices

  The NM-CYD-C5 and NM-RF-HAT support the BruceDevices firmware application.

• NM-Display-28inch

  The 2.8 inch ESP32-S3 display, co-developed with the NMTech Team. Designed for desktop AI assistants, smart home controllers and robotic applications like OpenClaw -- easy to use and versatile.

  • xiaozhi-esp32

    The NM-Display-28inch support the project xiaozhi-esp32, which XiaoZhi AI chatbot leverages the AI capabilities of large models like Qwen / DeepSeek, and achieves multi-terminal control via the MCP protocol.

• esp-claw

  ESP-Claw is Espressif's Chat Coding AI agent framework for IoT devices. It defines device behavior through conversation and completes the full loop of sensing, decision-making, and execution locally on Espressif chips. Inspired by the OpenClaw concept and reimplemented in C, ESP-Claw is lightweight, intelligent, and continuously evolving. With just an ESP32-series chip that costs only a few dollars, you can experience what makes ESP-Claw so nimble. RockBase-iot brach nm-cyd-c5 support board NM-CYD-C5, add built-in nmminer skill for managing NM's devices.

• NM-Display-420

  ESP32-S3 based 4.2-inch E-ink display board. Will publish soon.
