The MT3608 DC to DC Power Boost Module is a compact step-up (boost) converter designed to increase lower DC input voltages to a higher adjustable output voltage. It is widely used in battery-powered projects, portable devices, and embedded systems where a stable higher voltage is required from a low-voltage source such as Li-ion cells or USB power.
