The First Release of ESP-WROOM-32 Module Datasheet
https://www.electronics-lab.com/first-release-datasheet-esp-wroom-32-module/
It has been a while from the announcement of the new SoC ESP32 from Espressif. Recently, Espressif released the ESP-WROOM-32 module which is based on ESP32 SoC, the big brother of the well know ESP8266 WiFi module. ESP32 is a 2.4 GHz Wi-Fi and Bluetooth combo chip with dual CPU cores and a very rich […]
Charge-pump topology doubles voltage
https://www.electronics-lab.com/charge-pump-topology-doubles-voltage/
Michael Dunn has designed a circuit that is able to double the input voltage and breaks DC path. I once needed a voltage doubler circuit with no DC leakage path between input and output, and ended up devising this unusual 556- (dual 555 timer) based circuit with a “floating” voltage output. Charge-pump topology doubles voltage […]

An optical micro-displacement sensor from Omron Electronic Components Europe is capable of resolving 10 microns – one tenth the diameter of a human hair or the thickness of a coat of paint. by Graham Prophet @ edn-europe.com The high resolution of the Z4D sensor suits it for paper thickness and multi-feed detection office equipment and […]
iPhone Battery Charger / Tester
https://www.electronics-lab.com/iphone-battery-charger-tester/
mozzwald.com has designed an iphone battery charger /tester. I have seen technicians often replace batteries when they may not necessarily need to be or ignore the fact that they could be the cause of the issue at hand. To remedy this I designed a basic iPhone battery charging breakout board system. The system can charge […]

Silicon-air Battery A New Achievement in Energy Storage Area
https://www.electronics-lab.com/silicon-air-battery-new-achievement-energy-storage-area/
Researchers from Jülich Research Center (Jülich, Germany) announced their new invention, a silicon-air battery. The new battery features high energy density so it’s a lighter and smaller battery solution. Silicon-air battery is made of silicon which means it’s cheap to make from virtually unlimited resources rather than a rare earth material. It can deliver energy […]
