About Product

Features

i²draw measures the voltage and amperage drawn by the robot continuously throughout a practice or competition and makes it readily available through the Core Device Interface Module.

Ease of Use

Simply plug i²draw into your power line using built in powerpoles and connect directly to the core device interface module.

Affordable Price

Only $30 dollars can get you the sensor and helps to support FLL in Haiti.

Prevent Problems

By measuring current draw during practice, you can prevent fuse blowouts in competition.

About

What its for

01

Prevent Fuse Blowouts

Measure current draw in real time to predict issues and prevent problems in competition such as fuse blowouts which are common. AndyMark motors can draw as much as 11.5 amps each and FTC robots contain a 20 amp fuse.

02

Improve Consistency

Reading voltage and amperage allows you to account for voltage drops over time -- which correlates directly with motor power. This means programmers can now have consistant rpms on DC motors independant of battery voltage.

03

Many other uses

i²draw can be used in infinite ways to improve your robots performance on the playing field. Knowing current amperage and voltage is an invaluable tool which we feel all FTC teams should have access to.
