Meshtastic BASE Board Adds Super IO and Dual-Band Mesh Support

Super IO Board with Base DUO

The Meshtastic BASE board is a modular hardware platform designed for makers who want to build custom off-grid mesh communication devices. Developed by Muzi Works in collaboration with Elecrow, the system targets Meshtastic users who need flexible I/O, clean power design, and easy expansion. Instead of forcing a fixed layout, the BASE board lineup lets users choose the exact hardware combination that fits their project.

Muzi Works offers the Meshtastic BASE board in multiple variants, including Base Uno, Base Duo, and an optional Super IO expansion module. Each board focuses on low power operation and reliable wireless performance. The design supports DIY LoRa radios, portable communicators, and fixed mesh nodes without complex wiring or custom PCBs. This approach makes the platform useful for both beginners and experienced builders.

At the core of the Meshtastic BASE board design is Nordic Semiconductor’s nRF52840 microcontroller. This MCU provides low power consumption, integrated Bluetooth LE, and enough processing capability to handle Meshtastic firmware and peripheral control. The Base Uno targets single-radio setups, while the Base Duo adds support for dual-band LoRa configurations. The Super IO module expands GPIO, serial interfaces, and external device connectivity.

Super IO board front and back

The Meshtastic BASE board runs the standard Meshtastic firmware without modification. Users can configure nodes using the Meshtastic mobile app or desktop tools over Bluetooth LE or USB. The platform supports routing, encryption, GPS integration, and text messaging features provided by Meshtastic. Developers can also build custom firmware using Nordic’s SDK and open-source Meshtastic codebase. A few days earlier, we covered another Meshtastic device from the same company, the Muzi R1 Neo, a portable node that supports long-range communication and location tracking using built-in dual GPS.

Muzi Works sells the Meshtastic BASE board series directly through its online store. The Base Uno is priced at around $25, while the Base Duo costs $35, depending on availability and region. The Super IO expansion module sells separately for about $32. Users can purchase each board individually or combine them to build a complete modular mesh radio system. Purchase links are available on the Muzi Works official website and partner stores.
