uMesh – A self-contained, battery operated ESP32 module
https://www.electronics-lab.com/umesh-self-contained-battery-operated-esp32-module/
Jarrett published a new project. It is a battery powered ESP32 module. I’ve been working on an ESP32 module. Part of the problem I’ve been seeing with inexpensive IoT dev boards, is that the design around the power system hasn’t been very good. Here’s my attempt to fix that. This is a battery-ready module with […]
Using NXP’s NXQ1TXH5 Qi Charging Circuit
https://www.electronics-lab.com/using-nxps-nxq1txh5-qi-charging-circuit/
Adding wireless charging to furniture and other consumer goods is a nice way to add some oomph to an otherwise boring product. NXP’s NXQ1TXH5 provides an interesting, albeit difficult-to-prototype way around the problem. Creating a Qi-compatible is as easy as assembling the example circuit shown in figure one. From a technical point of view, the […]

The Grove – Infrared Temperature Sensor Array (AMG8833) is a high precision infrared array sensor which based on advanced MEMS technology. It can support temperature detection of two-dimensional area: 8 × 8 (64 pixels) and maximum 7 meters detection distance. We provide both Arduino and Raspberry Pi demo for this sensor. It will be a […]
NXP’s MMA8451QR1 Accelerometer
https://www.electronics-lab.com/nxps-mma8451qr1-accelerometer/
Process computer designs usually start out with an accelerometer. As reliability problems creep in, making the switch to a more “professional” solution is beneficial. Accelerometers are based on the MEMS principle: instead of being a purely solid-state affair, the inside of the chip contains a micromechanical motion sensor along with a small mass. In addition […]

Coinciding with the BT815 and BT816 advanced graphics controller ICs being ramped up into volume production, Bridgetek has introduced a series of accompanying entry-level development modules. Supporting a range of different display configurations, the compact (54.1mm x 85.60mm) VM816C modules each feature a BT816 device. Through these items, engineers will be able to utilise the […]
Using Ferrite Beads for Ringing Control in Switching Converters
https://www.electronics-lab.com/using-ferrite-beads-ringing-control-switching-converters/
“Ringing” is a common term referring to the undesired oscillation that occurs when a power semiconductor switch turns on or off in the presence of parasitic inductance and capacitance. Energy stored in the parasitic junction capacitance of the switch is released during the switching transition and rings with parasitic inductance coming from the stray fields […]
