These hexagonal male-female aluminum standoffs are intended specifically for use with the Raspberry Pi. They keep parts spaced 11 mm apart, which is just the right height for mounting expansion boards with standard-size female headers, and they have 4mm-long M2.5 threads that are just the right size for the Raspberry Pi’s mounting holes. These standoffs are sold in packs of 4.

The S9V11F5 switching step-up/step-down regulator efficiently produces 5 V from input voltages between 2 V and 16 V. (Note: it requires an input voltage of at least 3 V to start, but it can operate down to 2 V after startup.) Its ability to convert both higher and lower input voltages makes it useful for applications where the power supply voltage can vary greatly, as with batteries that start above but discharge below 5 V. The very compact (0.3″ × 0.45″) module has a typical efficiency of over 90% and can supply a typical output current of up to 1.5 A when the input voltage is around 5 V.
