Feature: Size: 20 x 20 x 5mm/0.78 x 0.78 x 0.19(inch) (approx) Module properties: non-isolated boost Rectification: non-synchronous rectification Input voltage: 2.5V-6V Output voltage: 4V-12V (adjustable) Output current: 1000mA (Max) Conversion efficiency: 92% (the highest) Switching frequency: 1MHz Output ripple: 20mV (max) Load regulation: &pm; 0.5% Voltage regulation: &pm; 2.5%

Note: Formula output: VOUT = (R1/R2 +1v) * 0.6V Default resistance: R1 = 150K R2 = 20K (unit:ohm) By adjusting the voltage of this formula, which is calculated by the formula resistors, R1 or R2, replace the resistor can be calculated on the desired output voltage. The R1, R2 can be removed and replaced with other resistance. Example: I want the output voltage is 8V, then want to replace R1 , then 8 = (R1/20K +1) * 0.6, calculate R1, put on it. Package includes: 3 x Module
