RioRand DC-DC Buck Boost Converter 5V-25V to 0.5-25V Regulated Power Supply Module, Green LED Voltage Display

Product parameters:
Input voltage: DC 5.0-25V
Output voltage: DC 0.5V-25V (adjustable)
Continuous Output Current: 2A (max)
Continuous Input Current: 2A (max)
Input / Output Power: 25W (max)
Display color: Green
Dimensions: 47 * 41 * 16mm (L * W * H)

Features:
Input and output voltage can display alternately
The starting state can be set freely.
This module has the function of controling the start-up and shutdown by the button. So it can control easily the state of output
This module have the big power MOS to protect the circuit in case of connecting reversely. This can improve the efficiency and reliability.

Working Mode:
Input voltage mode: Boot default display input coltage, display as ".",LED indicator ON,the output off. Output voltage mode: Press S1 switch to output voltage mode, display ".",LED indicator off, if turn off the output, display "OFF".
Alternate mode: Press S1 key again, display input/output voltage alternately in 3 seconds,press S1 again switchi to "input voltage mode".
Memory Mode:
Long press S1key for 3 seconds, the module automatically remembers the current work status as the default power-on state.
[0]means boot default display input voltage
[1]means boot default display output voltage
[2]means boot default display input/output voltage alternately

Package include:
1x DC Boost-buck Converter
