1. Circuit board specific power module, compatible with 5V and 3.3V Suitable for MB102 circuit board2. Input voltage 6.512V DC or USB power supply3. Output voltage 3.3V, 5V, selectable by jumper4. Output current Less than 700mA value5. The upper and lower channels are independently controlled and can be selected to 0V, 3.3V and 5V. Two sets of builtin 3.3V and 5V DC output pins with selflocking power switch indicator lights1. The module inputs 6.5V12V. If you input 5V, you will not get 5V voltage.There is a voltage difference between the input and output of the voltage stabilizing circuit, otherwise it will not work.2. If you only use 3.3V, the 5V output there can get a stable voltage of 3.3V.3.
