Why Micro

Small, low-power,
nothing to develop.

The three things embedding needs, on one board.

Embeddable

A small board that fits inside your product.

76 × 48 × 20mm, M3 screw mount, powered over USB or a ZH connector.

Battery / Solar

Years of operation on battery or solar.

0.2W average (on LTE-M) and timer sleep from 1 second.

Firmwareless

No firmware development.

obnizOS is preinstalled.

Use Cases

Where it is used.

Turn your product into a smart product

Embed it and your existing product connects over Wi-Fi, LTE, or BLE.

See the embedding solution

Sensing outdoors and off-grid

Pair it with a solar panel and battery for farmland, parking lots, and infrastructure with no mains power.

See facility monitoring

Failure prediction from vibration and heat

The built-in 3-axis accelerometer and temperature sensor continuously measure motors and pumps.

See failure prediction

From a small PoC to mass production

Evaluate with a single unit, then ship the same module in production.

FAQ

Frequently asked questions

Q. When should I choose Kilo vs. Micro?
Choose Kilo to connect industrial equipment or PLCs over RS232 / 485 / CAN / Ethernet. Choose Micro for embedding into your own product, battery-powered outdoor use, or when you need more GPIO. Both run the same obnizOS, so your cloud-side code and operations are identical.
Q. How do I embed it in my product?
Mount it with M3 screws and supply 5V over USB or the ZH connector. Connect to your own board through the ZH8 expansion header (digital I/O, analog, UART, I2C, SPI). Talk to us about production assembly and certification.
Q. How long does battery operation last?
It depends on sampling interval and connectivity. Sampling once every 10 minutes runs for over a week on four AA batteries, and with a solar panel it can run unattended for years. We size it per use case.
Q. Is firmware development really unnecessary?
Yes. Micro ships with obnizOS preinstalled, and your logic is written in JavaScript on obniz Cloud or through MCP / APIs. There is no on-device coding, cross-compiling, or flashing. If you need a little on-device processing, the Lua plugin is available.
Q. What about security?
TLS 1.2 with elliptic-curve encryption, per-device public-key authentication, and microcontroller-based resistance to kernel-level malware come standard. obnizOS has been in production since 2018 with over 40,000 units deployed.
Q. Can I buy it?
It is currently available through sales inquiries (consumer sales coming soon), as part of obniz solutions such as smart product enablement and facility monitoring.
