ESP32-C6 Gateway. Modular Radios. Battery-Ready.
Wi-Fi 6, BLE 5 and IEEE 802.15.4 on an open ESP32-C6 RISC-V module running Zephyr RTOS — expandable with Wireless M-Bus, NB-IoT/LTE-M and sub-GHz modules on two Click-compatible slots. Battery-backed, Wasm-ready, and manufactured in the EU.
One board. Swap-in modules.
A0 is the ESP32-C6 gateway board. Running Zephyr RTOS, it provides native Wi-Fi 6, BLE 5 and IEEE 802.15.4 with secure boot, flash encryption and a Trusted Execution Environment, plus two BUS1/BUS2 expansion slots (MikroE Click-compatible) for radio and cellular modules. It is powered over USB-C, an external VIN supply, or a single-cell Li-ion battery with on-board charging.

Expansion modules.
Fit the connectivity a deployment needs in either BUS1 or BUS2. In-house modules cover cellular, metering and sub-GHz, while the Click-compatible footprint opens the wider MikroE ecosystem.
Native radios plus plug-in modules.
Wi-Fi 6, BLE 5 and IEEE 802.15.4 are built into the ESP32-C6, while Wireless M-Bus, NB-IoT/LTE-M and sub-GHz arrive as modules on the BUS1/BUS2 slots — all sharing one Zephyr networking stack.
Built for Industrial IoT.
Everything you need for smart metering and industrial automation in a modular, open-source platform.
Wi-Fi 6, BLE 5 and IEEE 802.15.4 are native on the ESP32-C6. Add Wireless M-Bus, NB-IoT/LTE-M or sub-GHz with plug-in modules on the BUS1/BUS2 slots — all sharing one Zephyr networking stack.
Power A0 over USB-C, an external VIN supply, or a single-cell Li-ion battery with on-board MCP73831 charging. Ideal for permanent and battery-backed deployments.
Two MikroE Click-compatible expansion slots take SIM7080G, WMBUS and E07-400M10S modules — or any off-the-shelf Click board — for radio and cellular connectivity.
Secure boot, flash encryption, and hardware crypto accelerators built into the ESP32-C6. mTLS for cloud backhaul. Zephyr RTOS provides memory protection and process isolation for mission-critical industrial deployments.
WAMR (WebAssembly Micro Runtime) on Zephyr lets you deploy and update logic remotely via Propeller. Run AI inference, data transforms, and custom processing on-device without firmware reflashing.
All hardware designs and firmware are open source. Customise and extend as needed.
Where A0 deploys.
Smart Metering
Collect utility consumption data from wireless meters and relay it securely to Magistrala.
Industrial Automation
Monitor equipment health and trigger alerts at the edge without cloud round-trips.
Remote Deployments
Battery-backed operation in locations without permanent power: pipelines, silos, and remote infrastructure.
Edge AI
Execute lightweight inference workloads on-device using Propeller's Wasm runtime.
Deploy Wasm. No reflash.
WAMR (WebAssembly Micro Runtime) on Zephyr lets A0 receive and execute workloads pushed from Propeller over MQTT. Update device logic — AI inference, data transforms, protocol bridges — without shipping a new firmware image.
Add BeagleV-Fire. Get Linux.
Plug A0 onto a BeagleV-Fire RISC-V Linux board and the combination becomes the A1 gateway — full Linux compute with containers, Node-RED, and local AI, plus A0's native and modular radios for device connectivity.
Connects with the full stack.
A0 is designed to run Magistrala and Propeller workloads at the extreme edge.
Running in the field.
A0 hardware is deployed in production environments and backed by European Commission research funding.
Ericsson Smart Factory
A0 deployed for industrial IoT sensor collection and edge processing in Ericsson's smart factory environment, validating multi-protocol wireless at production scale.
ELASTIC Project
A0 hardware was developed under the EU Horizon Europe ELASTIC research programme — validating cloud-to-MCU IoT architectures across industrial edge deployments.
ELASTIC project →Made in the EU
Designed, manufactured, and quality-controlled within the European Union. Eligible for EU public sector and defence procurement requiring domestic supply chains.
Common questions.
What is Zephyr RTOS?
Zephyr is a small, scalable real-time operating system designed for resource-constrained and embedded devices. It is maintained by the Linux Foundation and supports a wide range of microcontrollers including the ESP32-C6 used on the A0 Board.
What is the difference between A0 and A1?
A0 runs Zephyr RTOS on an ESP32-C6 microcontroller, optimised for low power and constrained environments. A1 runs full Linux on a RISC-V compute board (BeagleV-Fire) and supports containers and heavier workloads.
What expansion modules can I plug into A0?
A0 has two expansion slots (BUS1 and BUS2) on a MikroE Click-compatible footprint. In-house modules include SIM7080G (NB-IoT/LTE-M + GNSS), WMBUS (Wireless M-Bus) and E07-400M10S (sub-GHz 400 MHz); any off-the-shelf Click board also fits.
Can I customise the A0 firmware?
Yes. The A0 firmware is open source. You can modify, extend, or replace it. The hardware schematics are also published, so you can adapt the board design for your specific requirements.
Does A0 support Propeller Wasm workloads?
Yes. A0 includes a lightweight Propeller runtime for Zephyr RTOS that allows the device to receive and execute Wasm workloads deployed remotely through the Propeller manager.
