The power supply of the Whadda breadboard 3.3V / 5V is the perfect power supply companion for your standard MB-102-compatible 830-point breadboard. Simply plug the module into a compatible breakstart, supply the module with power (either with a USB-C cable or through the standard DC barrel plug), and your break-record power rails will be provided with a selectable 3.3 / 5 V on the top and a constant 5 V on the bottom. https://elecena.pl/product/28347993/whadda-wpm467-breadboard-3-3v-5v-power-supply-module 2025-04-12 https://elecena.pl/product/28347993/whadda-wpm467-breadboard-3-3v-5v-power-supply-module 2025-08-17
