## Description

Parameters:  -Size: 65x36x15mm(LxWxH) -Work Temperature: -40 degree to +85 degree -Weight: 9g -Input Current: 3A Max(The Recommended Current: 0-2A ) -Input Voltage: 5-36V (The Recommended voltage is 4.5-35V.) -Output Voltage: 1.2-35V (The Recommended voltage is 1.5-32V.) -Switching Frequency:150KHz Transfer Efficiency: less or equal to 95%  -Output Ripple: <200mV (The higher voltage, the greater current and ripple.)  -Connection Mode: terminal blocks or welding blocks With power indicator. -self-calibration voltmeter display.  -Adopting more advanced voltage microprocessor, the error of the voltmeter is +/- 0.05V, the range is 0-35V. (Note: Please make sure the input voltage is above 4.5V to ensure the accuracy.)   How to use:  -Wiring connection: IN+: connect IN+ to your Input + IN-: connect IN- to your Input - Out+: connect OUT+ to your output + Out-: connect OUT- to your output -  -Touch the button(short press) to switch the measurement input or output voltage, and there is an indicator to indicate which voltage is being measured, and keep the last setting, even if it is powered off and then on.  Note:  -1. Please make sure that you use this module within its working range; do not output short-circuit or charge the battery, otherwise the board would burn. -2. When you set the parameter, please use the module after you make sure output voltage is stable to avoid any possible damage.
