More space to work
Replace a small pile of first-line instruments with one pocket-sized station.
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.
Five v1 engineering prototypes built. Beta testing is the next step.
Why DOGS²
Your bench is crowded.
Your USB ports are full.
Power almost anything. From almost anything.
No host computer required
Use the built-in display, encoder and controls for standalone operation. Bluetooth connects your phone for data terminals, bus sniffers and live current-consumption graphs—all without occupying another USB port.
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.
Run a sensitive analog rail and a higher-power rail from the same compact device. Set voltage and current limits digitally and watch consumption during startup.
- Channel A
- Linear · up to 20 V / 1.5 A · 12.5 µA current-measurement resolution
- Channel B
- Switching DC/DC · up to 48 V / 3 A continuous (5 A peak) · 125 µA current-measurement resolution
- Input
- 5–90 V DC or USB Type-C
- Regulation
- CV / CC
Engineering parameters are being refined during v1 testing.
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.
Measure
Analog voltage probe, logic-state detection and frequency measurement. View live current-consumption graphs on your phone over Bluetooth.
Inspect buses
UART, RS-485, CAN and I²C receive, filter and transmit tools. An I²C master terminal and passive sniffer are included. LIN and 1-Wire support is in development.
Generate
Square-wave generation from 1 Hz to 100 kHz with a 1–99% duty cycle, plus a power pulse generator up to 20 V / 1 A.
Current status
Working hardware.
Development in public.
Five first-generation engineering units have been assembled. Power, measurement, signal generation and core interface tools are working; 1-Wire and LIN support are in development.
- Hardware revision v1 built and under test
- ESP32 firmware in active development
- A transparent enclosure is in development
- Open hardware documentation being published
- External beta testing planned next
- Crowd Supply campaign is the target commercial step
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.

Inspect it.
Build it.
Improve it.
The v1 hardware design is released under the CERN Open Hardware Licence Version 2 — Weakly Reciprocal. Schematics, manufacturing files, BOMs and design sources are available for review. Firmware and documentation will also be released under open-source licenses; the specific licenses will be stated in the repository.
