Workbench Wednesdays

Multi-layer ceramic capacitors (MLCCs) are so ubiquitous that you see them on almost every printed circuit board. Engineers and supply chain managers often ask whether polymer …

I dive into Pico Technology’s latest PicoScope oscilloscope software, PicoScope 7. Using a PicoScope 2000A (from the element14 Community), James walks through key measurements and …

The B&K Precision DAS60 is a data recorder. It features 6 wide-range voltage inputs, 16 digital channels, and RTD thermal sensor inputs and comes in a small compact form factor. In …

Check out NXP’s latest microcontroller boards. These boards of their new MCX-A and MCX-N microcontrollers. The form factor is what NXP calls Freedom (FRDM.) The MCX line of …

A long time ago, I made a video suggesting math was unnecessary to determine proper pull-up resistor values. Like most generalized statements, that suggestion is not always true. …

In August 2022, Nordic Semiconductor announced its first Wi-Fi product. The nRF7002 is a dual-band (2.4 and 5 GHz) Wi-Fi 6 compatible companion IC. It does not have a …

During the component shortage, I got to know Raspberry Pi’s RP2040 microcontroller. It is a dual-core Arm Cortex-M0+ with about 262 kilobytes of RAM. The feature I like most is the …

Often I hear this question: “how can I get better solder joints?” Without looking at anything they are doing, I already know that they could be using more flux. Or, as I point out …

A powerful, but an underused feature of digital oscilloscopes is the trigger circuit. Learn from James how to use an oscilloscope’s trigger to find glitches, measure pulse widths, …

When running on a battery, it is important to know what parts of your circuit draw the most current. Profiling is a process where you look at sections of code or interactions with …
