- 15:5515:55, 20 January 2024 diff hist +341β N Glossary:ZIF Connector β Created page with "A ZIF or Zero Insertion Force connector is one in which a clamp of some sort is closed to make a good contact after the mating parts have been engaged, instead of the force being applied during insertion. They are commonly used for delicate ribbon cables, and for test rigs where many insertions of devices under test will routinely be made." current
- 15:4415:44, 20 January 2024 diff hist +253β N Glossary:Thermal Runaway β Created page with "Some electronic components and circuits take more current as as they get hotter. Unchecked, this can lead to a positive feedback effect in which excessive heat causes still more heat to be generated, ending in a catastrophic failure and possibly a fire."
- 15:3415:34, 20 January 2024 diff hist +315β N Glossary:SMD β Created page with "A Surface Mount Device or SMD is an electronic component designed to be mounted on the surface of a printed circuit board, instead of having leads which pass through holes in the board, soldered on the reverse side. Surface mount devices are generlly smaller, often much smaller than their through-hole equivalents."
- 15:2815:28, 20 January 2024 diff hist +322β N Glossary:Ribbon cable β Created page with "Ribbon cables are cables with the conductors laid side by side to form a ribbon, rather than bound together in a bunch. The conductors may be individual insulated wires or may be copper tracks like those on a printed circuit board, laid on a fexible substrate. They are nomally used in conjunction with special connectors."
- 12:3412:34, 20 January 2024 diff hist +415β N Glossary:NFC β Created page with "NFC or Near Field Communication is a set of technologies allowing electromagnetic communication between two devices, usually no more than a few centimeters apart. Each device contains a coil of wire and together they form a transformer through which data can be passed. A small amount of power is also often passed to an NFC device such as a security tag, having no power source of its own." current
- 12:2212:22, 20 January 2024 diff hist +274β N Glossary:LIDAR β Created page with "LIDAR or Light Imaging, Detection and Ranging is a technology similar to radar but using visible or infrared light instead of radio. As with radar, the distance of an object is determined by measuring the time taken for a pulse of light to be reflected off it and to return." current
- 12:1412:14, 20 January 2024 diff hist +150β N Glossary:LDO β Created page with "A LDO or Low Drop-out regulator is a voltage regulator which produces the required output voltage even when the input voltage is only a little higher." current

Class A drives the output throughout a cycle, and is the least efficient. Class B drives the output for only a half cycle. Usually, a second Class B driver drives alternate half cycles. Class C drives the output for less than half a cycle and generally drives a tuned circuit to restore the output (typically in a transmitter) to a p..."
- 11:4911:49, 19 January 2024 diff hist +314β N Glossary:PWM β Created page with "PWM or Pulse Width Modulation is a highly efficient method of power control in which the power is switched on and off very rapidly. The ouput is then smoothed with a capacitor and/or inductor and the relative on and off times then determine the power that is delivered."
