Helium Analog Extension Board



The Analog Extension Board connects to the Helium Atom Development Board to prototype connected products using readily available analog sensors.

The Helium Analog Extension Board is great for measuring DC voltage (0-24V) and current (0-500mA) and for working with analog sensors that vary voltage or current depending on their reading. Common sensor standards like this are 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. Refer to the datasheet for further information.

If you're looking for Digital input/output (reading switches, driving LEDS, etc), please check out our Helium Digital Extension Board.

*Requires a Helium Atom Development Board for full functionality.
