1. Breadboard-specific power module, compatible with 5V and 3.3V Suitable for MB102 breadboard 2. Input voltage: 6.5-12V (DC) or USB power supply 3. Output voltage: 3.3V, 5V, jumper cap selectable 4. Output current: Less than700ma (peak 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 lights 1. 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!
