Allegro MicroSystems has expanded its AI data center portfolio with ACS37030, ACS37002, AHV85311 and A89333. The parts support 800 V power distribution and 48 V cooling systems, with the current sensors aimed at fast isolated current monitoring, the gate driver eliminating the need for a separate isolated bias supply and the motor controller supporting efficient…
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…
This article explains how to establish secure communication between two LoRa end-node devices using Lora E5 mini boards. LoRa, which stands for “long range,” is a wireless technology with the ability to send small amounts of data over large distances. Two end-node devices can exchange encrypted messages. The transmitting device encrypts the message before sending…

In the previous article, we looked at what ultra-high reliability means for IEEE 802.11bn, the standard behind Wi-Fi 8. Compared with Wi-Fi 7, it aims for 25% more throughput at a given signal level, 25% lower 95th-percentile latency, and 25% fewer lost packets, especially during roaming. Much of this work happens at the physical layer,…
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…
