1. DOUBLE PANEL DESIGN The breadboard power supply adopts double panel design, a beautiful and practical layout. Specially designed two pin mounting holes that can be attached directly to the perforated plate for expansion experiments. 2. Easy to use and connection: Input and output use multiple pin headers for easy use and connection. We 5 modules for all your needs. All components are carefully selected and of high quality. 3. Brass material: The connection of the power supply module is made of highquality brass material, which has a stronger and more stable conductivity and ensures efficient information transmission and flexible mechanical rigidity. 4. 3way output: The compact and practical design ensures more stable operation. 3.3 V (0.05 V error), 5.0 V (0.05 V error), 800 mA (load current must not exceed 800 mA), 12 V (input 12 V direct output), PCB size 4.5 x 4.5 cm / 1.77 x 1.77 inches.
