1. Breadboard-specific power module, compatible with 5V and 3.3V Suitable for MB102 breadboard2. Input voltage: 6.5-12V (DC) or USB power supply3. Output voltage: 3.3V, 5V, jumper cap selectable4. Output current: Less than700ma ( value)5. The upper and lower channels are independently controlled and can be switched to 0V, 3.3V, and 5V.Two sets of onboard 3.3V and 5V DC output pins with self-locking switch indicator lights1. The module inputs 6.5V-12V. If you input 5V, you will not get 5V voltage.There is a voltage difference between the input and output of the voltage stabilizing chip, otherwise it will not work.2. If you only use 3.3V, the 5V output over there can get a stable voltage of 3.3V.3. This is the power module without breadboard, thank you!DUE to Different Batches, The Apperance, Color and Printing of the Product May Be Different, which does not attract use.Material: PCBcolour: BlackPackage Contents: 10 Supply ModuleOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
