OsprioMini

Compact OSDP hardware for the bench

The compact OSDP bench companion

Osprio Mini is a hardware OSDP instrument: USB-C to your laptop at one end, RS-485 to the bus under test at the other. You drive it from Osprio View, where capture, emulation, provisioning, conformance and raw serial monitoring each get a focused workspace — switch Mini to the firmware app that serves the job.

Firmware-defined hardware

One device. Five different instruments.

Osprio Mini is a general-purpose hardware platform: what the device actually does is decided by the purpose-built firmware app running on it, and those apps are updatable in the field. Owning the hardware means owning the roadmap too — every app we release afterwards installs onto the Mini you already have, from Osprio View, at the push of a button.

Capture

Mini listens silently on a live bus without adding onboard termination. Osprio View decodes the traffic in real time and gives you the tools to isolate, inspect and save exactly what matters.

Live OSDP traffic decode
Secure Channel inspection
Targeted filtering and quiet-mode folding
Encrypted capture export and offline review

Provisioner

Mini becomes an access control unit for controlled, point-to-point PD commissioning. Set addresses and baud rates, write Secure Channel keys and verify each device before it is moved onto the live installation.

Live quick-step and batch modes
Address and baud-rate assignment
Verified install-mode SCBK keying
Profile-backed deployments and key export

Emulator

Mini joins the bus as either an access control unit or a peripheral device, letting you exercise real hardware from the other side of the conversation. Build repeatable behaviours, send commands and events, and test Secure Channel workflows without needing the missing half of a system.

ACU or PD emulation
Configurable PD capabilities and profiles
Secure Channel and file transfer
Reusable commands, events, sequences and triggers

Learn more →

Conformer

Mini drives repeatable OSDP conformance testing against a real device under test and evaluates its behaviour case by case. Run focused checks or a complete suite, then review results alongside independently captured bus evidence.

PD and ACU test modes
Browsable conformance test catalogue
Individual or full-suite execution
Per-command results with captured bus evidence

Bridge

When all you need is the wire, Mini becomes a transparent USB-to-RS-485 adapter for your existing tools. It provides direct access to the physical bus without imposing an OSDP workflow or adding onboard termination.

Platform Highlights

Focused, wired, and easy to move between tasks

Small enough to bring anywhere

Osprio Mini is barely larger than a coin — small enough to drop in a bag and carry to whatever bench, panel, or lab has the device you need to test. There is no rack unit to mount and no instrument cart to wheel around.

Because it is host-powered over USB-C, getting going is just plugging into your laptop and the bus — so testing OSDP hardware happens wherever you and the device under test happen to be.

One workspace at a time

Osprio Mini runs the single Osprio View workspace you need right now — Capture, Emulator, Provisioner, Conformance, or Serial Monitor — then switches cleanly to another with a quick firmware swap when the job changes.

Focusing on one workspace at a time is what keeps the hardware small and simple; it trades Pro's concurrency for a compact, host-powered unit that does one thing well.

USB-C + RS-485

Just two connections: a USB-C link to your Osprio View host, and a pluggable screw terminal onto the RS-485 bus. No adapters to assemble and no breakout to wire up.

Mini draws its power from USB, never from the bus, and deliberately carries no onboard termination resistor. Its RS-485 interface is designed to avoid changing the installation's termination while it listens and talks on the bus.

That makes Mini suitable for attaching to an existing, correctly terminated segment without silently adding another terminator. As with any RS-485 instrument, connect it as a bus node and preserve the installation's existing topology and two-end termination.

LED indicators

On-device LEDs give immediate visual feedback on what the unit is doing — which app is running, whether it is active, or whether it has latched an error — without the cost and bulk of a full screen or local navigation controls.

It is the right amount of on-device signal for a bench companion: enough to read state at a glance while the detailed view stays in Osprio View on your host. See the LED behaviour reference for exactly what each color and pattern means.

Field firmware upgrades

Update the device in the field as new workspaces and workflows are added to the Osprio View stack, so the hardware keeps pace with the software.

A unit you buy today gains capability over time instead of going stale — the workspace catalog grows and Mini grows with it.

By Design

What Mini leaves out, and what it grows into

No battery assumptions

Host-powered by design, with offline and standalone operation deliberately left out. That trade is what keeps the platform compact, simple, and inexpensive for benched and staged work.

Ready for every workspace

The same small unit covers bus capture, ACU and PD emulation, PD commissioning, conformance testing, and raw USB-to-RS-485 bridging — one firmware app at a time. You are not buying a single-purpose tool.

Deterministic embedded timing

Mini runs time-sensitive OSDP work on its embedded microcontroller instead of relying on desktop scheduling. Bus responses and protocol timing stay close to the wire while Osprio View handles configuration, control, and results.

Future workspace path

Aligned with the Osprio View workspace model, Mini can gain new firmware apps and workflows in the field, extending the hardware you already own instead of forcing a replacement.

Works With Osprio View

Use the same workspaces on a smaller hardware platform

Osprio Mini supports the current Osprio View workspace catalog through purpose-built firmware apps. Mini runs one app at a time, switching cleanly when the job changes.

Capture Workspace

Use Mini for live bus capture, secure channel inspection, and replay-focused review workflows.

Emulator Workspace

Switch into emulation when you need ACU or PD emulation from the same physical platform.

Provisioner Workspace

Switch into the provisioner app to commission PDs on the attached RS-485 bus — address, baud, and install-mode SCBK keying — while controlling Mini over USB-C.

Conformance Workspace

Use Mini to run repeatable PD or ACU conformance tests and review each result alongside captured bus evidence.

Serial Monitor

Switch to the Bridge app for transparent USB-to-RS-485 access, raw byte inspection, macros, and interactive transmit.

FAQ

We get these questions a lot

Does Osprio Mini need a battery or external power?

No. Osprio Mini is host-powered over USB-C — it draws power from the laptop or device running Osprio View, with no battery to charge, which keeps it compact for bench and staged work.

Can Osprio Mini run all Osprio View workspaces?

Yes. Osprio Mini runs the current Osprio View catalog — Capture, Emulator, Provisioner, Conformance, and Serial Monitor through the Bridge app — one workspace at a time over USB-C, switching cleanly when the job changes.

Can I use Osprio Mini as a traditional USB-to-RS-485 converter?

Yes. In Osprio View, switch the firmware app running on Mini to Bridge. Serial Monitor then drives it as a transparent USB-to-RS-485 bridge, and compatible host software can use the serial interface exposed by the Bridge app. You can switch it back to any of the OSDP apps whenever you need them.

Why not use an off-the-shelf USB-to-RS-485 converter?

A generic converter leaves protocol timing and bus responses to the host operating system, where scheduling behaviour and jitter vary. Mini runs the OSDP side on dedicated hardware, delivering consistent, real-time responses to bus activity and meeting OSDP physical-layer timing requirements even at high baud rates. The architecture also scales cleanly: dozens of Minis can connect to one host and emulate arbitrary PDs against an ACU for large-scale and stress testing. Read more about the Osprio system architecture.

How is Osprio Mini different from Osprio Pro?

Osprio Mini is compact and host-powered over USB-C and switches its firmware app to change workspace; Osprio Pro is battery-backed, runs every workspace from one unified firmware image with no app switch, and adds a display, secure element, and Bluetooth for untethered field work.
