DC-DC Step-Down & Step-Up Converter 1.8V-5V to 3.3V

DC-DC Step-Down & Step-Up Converter 1.8V-5V to 3.3V

This compact DC-DC converter module offers a fixed, regulated 3.3V output from a wide input voltage range of 1.8V to 5V. It combines both step-down (buck) and step-up (boost) capabilities, making it ideal for low-power applications where voltage stability is essential. This module is handy for powering WiFi, Bluetooth, and other low-power wireless modules such as the ESP8266, HC-05, and NRF24L01+.
