ODrive – High performance motor control

Description Stepper motors are ubiquitous in hobby robotics projects: If you make a robotics or automation project today, it is very likely you will use them. Almost all DIY projects from 3D printers and CNC mills, to other kinds of projects like air hockey robots, use them. However in industrial automation, brushless servomotors have taken over, and it's clear why: They don't lose steps, are much more powe ...

Range of I2C-bus NXP extends with no-offset buffer

The PCA9525 is a monolithic CMOS integrated circuit for bus buffering in applications including I²C-bus, SMBus, DDC, PMBus, and other systems based on similar principles. The buffer extends the bus load limit by buffering both the SCL and SDA lines, allowing the maximum permissible bus capacitance on both sides of the buffer. The PCA9525 includes a unidirectional buffer for the clock signal, and a bidirecti ...

TI claims zero-drift op amp first

Description The OPA2188 operational amplifier uses TI proprietary auto-zeroing techniques to provide low offset voltage (25 µV, max), and near zero-drift over time and temperature. This miniature, high-precision, low quiescent current amplifier offers high input impedance and rail-to-rail output swing within 15 mV of the rails. The input common-mode range includes the negative rail. Either single or dual su ...

Easy IoT weather station with multiple sensors

A weather station is a fun project that teaches you a ton about electronics with the added benefit being an actually useful little device. The project requires a bunch of cheap parts and sensors totaling less than $15, and the whole thing ends up fitting in your hand. The station creates a web site that monitors temperature, dew point, humidity, pressure, light index, and rain (Thingspeak channel). It’s a p ...
