This is my mini lab bench power supply, built around a DPS3003 (or compatible DPS) as its primary component. It offers two modes of operation: powered by battery or powered by an external DC source. This versatility makes it extremely convenient to use. To assemble this project, you'll need the following parts: - A 3-position switch available on Banggood at https://www.banggood.com/Forward-Reverse-Switch-3-Positions-6-Pin-Switch-p-1167146.html?cur_warehouse=CN - A DC power jack obtainable from Banggood at https://www.banggood.com/1Pc-DC-Power-Jack-Socket-Power-Outlet-Power-Socket-Female-Panel-Mount-Connector-p-1177643.html?cur_warehouse=CN - Banana jacks sourced from Banggood at https://www.banggood.com/2Pcs-4mm-Nickel-Plated-Binding-Post-Banana-Jack-Socket-Plug-p-953213.html?cur_warehouse=CN - Spade connectors available on Aliexpress at https://www.aliexpress.com/item/32800318960.html - A DPS3003 or similar model from Aliexpress at https://www.aliexpress.com/item/32685187020.html - Cables for connecting the components - Four M3 screws to secure the parts together - An optional banana-alligator cable available on Banggood at https://www.banggood.com/P1041B-6-in-1-1M-4mm-Banana-to-Banana-Plug-Test-Lead-kits-Alligator-Clip-Clamp-p-1254539.html?cur_warehouse=CN The connections should be straightforward and self-explanatory.
