Navitas Semiconductor has introduced the G4H08MT23GB4 2300 V full-bridge SiC power module family in the SiCPAK™ form factor, with an 8 mΩ RDS(ON), an aluminum nitride active-metal-braze substrate and isolation above 5 kV. The modules use fourth-generation GeneSiC™ Trench-Assisted Planar™ architecture for solid-state transformers, grid-scale battery energy storage systems, solar inverters and EV megawatt charging…
In previous tutorials, we discussed the Inter-IC Sound (I2S) digital audio protocol and the I2S peripheral on ESP32 chips. Now, let’s apply these concepts in a hands-on project. This project turns an INMP441 I2S microphone and ESP32 into a live, browser-based audio visualizer. ESP32 captures sound through the microphone, analyzes each block of audio, and…
In the previous article, we covered how the I2S protocol works, from its three wires (BCLK, WS, SD) to the clock arithmetic that ties them together. We also looked at the one-bit delay that trips everyone up and the controller/target and transmitter/receiver roles. That’s the foundation for everything that follows. In case you could use…

The central test is whether a robot’s safeguards still protect people when the information they rely on is manipulated. Safety and security teams can begin by tracing the inputs behind each protective decision, challenging them, and revisiting the evidence as the robot changes. They can start with these five questions: What does each protective function…
If you’ve ever said “Hey Google” to a phone sitting across the room, you’ve used embedded AI. However, the phone didn’t stream every second of audio from your location to a data center while it waited for the wake word, the phrase that activates the assistant. Instead, a tiny neural network running on a low-power…
Welcome to the Engineering Deep Dive: Highlights & Technical Questionnaire This collection outlines key engineering challenges on our Electro-tech-online forums across multiple domains—including power electronics, motor selection, PCB manufacturing rules, circuit simulation, and RF…
UM 3561 is an excellent Siren generator IC widely used in Toy applications and Surveillance systems to generate different tones. It a ROM (Read Only Memory) IC which can be operated in 2 pen cells and it functions normally down to 2.4 volts. Using only a few components, it is very easy to construct a…
