Helium Analog
Extension Board


The Helium Analog Extension Board measures DC voltage (0-24V) and current (0-500mA) and works with analog sensors that vary voltage or current depending on their reading. Common sensor standards include 0-5V, 0-10V and 4-20mA and are often seen in automotive and industrial applications.

The Helium Analog Extension Board uses the INA219 current/power monitor.

For Digital input/output (reading switches, driving LEDS, etc), check out the Helium Digital Extension Board.
