Description
This INA219 breakout measures high-side current and bus voltage for the Raspberry Pi power-monitor project.
Project compatibility
- Connect VCC to the Pi’s 3.3 V rail and communicate over I²C.
- Place the screw-terminal current path in series with the positive side of the load being measured.
- The standard board measures buses up to 26 V and currents around ±3.2 A with its onboard shunt.
Before wiring
Never place the current terminals directly across a power supply; the monitored current must flow through the shunt in series. Respect the module, wire and connector current limits. The terminal block and header may require soldering.
