Joy-IT DEBO DVA 16-bittinen virta-, jännite- ja tehonvalvontakortti INA226:lla (SBC-DVA)

Embedded developers and IoT enthusiasts often need precise power profiling for their Raspberry Pi or Arduino projects, and the Joy-IT DEBO DVA 16-Bit monitoring board answers that call directly on the workbench. Built around the INA226 chip, this compact module measures bus voltage up to 26 V DC and current up to ±3.2 A with 16-bit resolution, streaming calculated power data over I2C at up to 128 samples per second. The 0.1 Ω shunt resistor with 1 % tolerance keeps measurements stable, while configurable alert thresholds let you flag over-current or under-voltage events in real time.

Key specifications

Why choose it

Unlike basic current sensors, the DEBO DVA 16-Bit delivers lab-grade accuracy in a breadboard-friendly form factor. You can monitor a solar charger, log battery discharge curves, or profile a motor driver without extra components. The wide I2C address range lets you stack multiple boards on one bus for multi-channel measurements, and the programmable alert pin can trigger an interrupt or shutdown routine when limits are exceeded.

Ideal use cases

• Real-time power monitoring for Raspberry Pi and Arduino projects
• Battery-powered device characterization and energy profiling
• Over-current and under-voltage protection circuits
• Solar panel and DC-DC converter efficiency testing
• Educational labs teaching I2C sensor integration

Good to know

The board ships as a bare module with pin headers, so you can solder it directly into your prototype or use jumper wires. It draws negligible power from the logic supply and leaves the measured circuit isolated from the I2C side. For quick start, Joy-IT provides example code for common microcontroller platforms, and the INA226 datasheet offers full register-level documentation.
