cost-effective SMD DC/DC module, as it offers a very wide output voltage adjustment range (0.8 – 30V), with an impressive 1A continuous output drive current. The output voltage can be pre-set using two resistors or, as shown in this hack, made variable by using a trimmer resistor. ...
AN2834 Application note How to optimize the ADC accuracy in the STM32 MCUs Introduction STM32 MCUs embed advanced 12-bit to 16-bit ADCs depending on the device. A self- calibration feature is provided to enhance ADC accuracy versus environmental condition changes. In applications involving...
our test point center-to-center spacing rule (TP to TP) was a whopping 2.54mm. This seems excessive, especially when I can place discrete surface-mount device (SMD) capacitors as close as 0.4mm apart without many complaints from
The DRV8871 DC motor driver needs just one resistor for limiting the current, and two decoupling capacitors. Then we have two potentiometers connected to the analog inputs of the microcontroller, one for adjusting the range of rotation and the other for adjusting the sensitivity of the servo. ...
Remember the ESP8266 ALWAYS outputs a start up message on GPIO1, so for that short time GPIO1 is ALWAYS an output. So be sure to add a series 330R resistor between GPIO1 and whatever output is driving that input to prevent shorting things out during the startup message. ...
Reflow Soldering usesSMT (Surface Mount Technology)to solder SMD (Surface Mount Devices) on to the PCB. In Reflow soldering there are four stages – Preheat Thermal soak Reflow; and Cooling. In this process solder paste is printed on the track of the circuit board where the component is to...
Modern SMD devices are realized with packages that drastically reduce proximity effects, thus allowing to use small spacing between components on a PCB layer. In some other applications, like CCD sensors for imaging purposes, the coupling between adjacent capacitors is exploited to transfer...
A simple capacitor connected to a battery through a resistor As soon as the connection is made, charge flows from the battery terminals, along the wire and onto the plates, positive charge on one plate, negative charge on the other.
We have successfully been able to use TicTocTrac, complete with charging and data recording/upload, without having to remove it from the case. This definitely gave a TicTocTrac a more finished feel. Thanks Jeremy! To make your own TicTocTrac, you’ll need: a soldering iron with SMD ...
