Blog #2: Getting Started with MAX40080 Current Sense Amplifier

taifur

What is a Current sense amplifier? The simplest technique for measuring current is to insert a small resistor, also called a current shunt, in series with the current to be measured. The voltage across the current sense resistor is measured, and the ...

Safer 3D printer with Current Sensing - Blog 2 - getting started with the Current6 Click

aspork42

What am I making? The project goals here are to use a current sensor to monitor the electrical current going to the hot end and heat bed on a 3D printer. If overcurrent (wires get shorted); we open a relay and make alerts. If undercurrent, the wires ...

Rover Motor Control - Blog #1

milosrasic98

In this blog, I present what I will be doing for the Experimenting with Current Sense Amplifiers design challenge. For the Just Encase design challenge I made a LoRa controlled rover that had 4-wheel drive with gearboxes that used rubber bands so they can slip. My plan is to upgrade the gearboxes to geared version, but keep the motor and driver safe using the provided current sensor as well as try doing some more precise…
