The Arduino Micro contains everything needed to support the microcontroller; simply connect it to a computer with a micro USB cable to get started. It has a form factor that enables it to be easily placed on a breadboard.
The Micro board is similar to the Arduino Leonardo in that the ATmega32U4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Micro to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port.

Raspberry Pi 5 provides two four-lane MIPI connectors, each of which can support either a camera or a display. These connectors use the same 22-way, 0.5 mm-pitch “mini” FPC format as the Compute Module Development Kit, and require adapter cables to connect to the 15-way, 1 mm-pitch “standard” format connectors on current Raspbery Pi camera and display products.These mini-to-standard adapter cables for cameras and displays (note that a camera cable should not be used with a display, and vice versa) are available in 200 mm, 300 mm and 500 mm lengths.

Measuring conducted emission is the simplest and most affordable method of getting some indication of whether a design can meet EMI/EMC requirements. A Line Impedance Stabilization Network (LISN) is an indispensable part of an EMC pre-compliance test setup.
In cooperation with Würth Elektronik, Elektor has developed a 5 µH, 50 Ω Dual DC LISN that supports voltages up to 60 V and currents up to 10 A.
The instrument measures RF interferences on both channels (the power supply) by means of 5-μH blocking inductances. The internal 10-dB attenuation network – one in each channel – contains a 3rd-order high-pass filter with a cutoff frequency of 9 kHz to protect the input of instruments like a spectrum analyzer from potentially harmful DC voltages or low frequencies coming from the EUT (Equipment Under Test).
