Microphone Connectors
Designed by Mark Little
Microphone connectors have rather solid pins and make a suitable power connector. The projects on this site that use microphone connectors for power use the convention below. Generally only the 2-pin and the 4-pin connectors are used. Normally, other required voltages are derived from the voltages provided. Although there is an Earth connection associated with each power rail, it is expected that each Earth pin will be at the same potential. Low current applications may use the same earth connection,
