The standard adapter from above at an angle: a long black board with a USB-C socket in the middle of its far edge, a silver slide switch on each half with 5V and 3V3 printed at its two ends, a red LED by each 5V label and a blue LED by each 3V3, and at each end a plus and minus mark over two columns of three pins, the pins pointing down underneath.

Breadboard Power Adapter, Standard 5 V / 3.3 V, 3-Pack

Three USB-C breadboard power adapters that plug into both pairs of rails at one end: a standard board with a 5 V / 3.3 V switch per side, a step-down that sets 1.25 to about 3.5 V, and a booster that sets about 4.3 up to 28 V. Which way round they go, why 5 V reads 4.7, and the half-amp fuse that limits all three.

Every pin, both switches and the 3.3 V regulator, with the + and − columns laid out the way the board fits a breadboard.

Product questions & answers ↓

Same plug, different voltage

All three fit the breadboard the same way and share one half-amp fuse. Pick by the voltage your circuit needs.
