Efficient DC 12V to 5V conversion for low-power electronics, evaluation of six modules
I am currently working on a vehicle-installed Arduino project. The device is designed to be powered constantly and I decided to use the car battery as the constant power source. I am designing the device for low power consumption, consuming 50mA or less, ’cause who wants to get stuck with a flat battery, right? Car ...

MLT-BT05 BLE module - a clone of a clone??
Previously I covered the HM-10 Bluetooth Low Energy (BLE) module and its clone, the CC41-A.  Those are two popular modules that allow simple BLE communication through a serial interface and are handy with Arduinos and other hobby micro controllers. Make sure you read that article first as it provides important background for this curious update. ...
