DOGS²

Open-source hardware

The first tool you connect to a new board.

DOGS² combines two programmable power supplies, current measurement, and everyday data-terminal and bus-sniffer tools in one compact standalone station.

Why DOGS²

Your bench is crowded.
Your USB ports are full.
Power almost anything. From almost anything.

01

More space to work

Replace a small pile of first-line instruments with one pocket-sized station.

02

No host computer required

Use the built-in display, encoder and controls for standalone operation. Bluetooth SPP provides terminal data, commands and telemetry, including current graphs in a compatible phone app—all without occupying another USB port.

03

Start where every board starts

Power is the first connection. DOGS² adds current visibility and diagnostics at that same moment.

Dual programmable power

Two rails.
One clear view.

Control two power rails independently from the same compact device. Set voltage and current limits, monitor actual output values, and view current graphs on the built-in display or in a phone app.

Channel A
LDO · 1.3–20 V · 2 A peak · 12.5 µA current-measurement resolution
Channel B
DC/DC · 1–48 V · 5 A peak · 50 µA current-measurement resolution
Input
5–90 V DC or USB Type-C
Regulation
CV / CC / overcurrent shutdown

Published v1 engineering-sample parameters, subject to testing and tuning. Peak current ratings are not continuous-current ratings; measurement resolution is not an accuracy specification.

Built-in tools

From first power-up to the first useful signal.

DOGS² is not a replacement for your oscilloscope. It is the compact set of tools you reach for before it.

Current-consumption graph on the DOGS² built-in display

Measure

Voltage and current monitoring, a logic probe and a frequency-meter input. View current-consumption graphs on the built-in display and in a compatible phone app over Bluetooth SPP.

I²C sniffer running on DOGS²

Inspect buses

UART and RS-485 terminals; CAN receive, filtering and transmission; a LIN bus sniffer; and an I²C passive sniffer and master terminal.

Signal generator running on DOGS²

Generate

Square-wave generation from 1 Hz to 100 kHz with a 3–20 V output, adjustable duty cycle and output control.

Current status

Working hardware.
Development in public.

Five v1 engineering samples have been assembled. View current graphs directly on the device and inspect LIN traffic alongside the power, measurement, signal generation and other interface tools. Hardware characterization and firmware tuning continue.

Why DOGS²?

One name.
Two meanings.

DOGS² stands for Dual Output Generator Supply Station. The name is also dedicated to the creator’s two dogs—Tessa, a German Shepherd, and Lissa, a Yorkshire Terrier—whose portraits appear on the boards.

The creator

Built by an engineer.
For engineers.

DOGS² is designed by Sergei, an electronics engineer with decades of hands-on experience in embedded systems, industrial electronics and product development. The project grew from a practical need: fewer instruments and adapters on the bench, without losing the tools required for everyday board bring-up.
