Power up your low-voltage wireless modules and accessories efficiently with this mini 2-in-1 DC-DC Step-Down & Step-Up Converter. Designed to work with devices like ESP8266 WiFi, HC-05 Bluetooth, CC1101 wireless chips, and LED modules, it converts input voltages from 1.8V to 5V into a stable 3.3V output, ensuring reliability in your DIY and development projects.

Key Features:

  • Fixed 3.3V ±4% regulated output for stable performance
  • Wide input voltage: 1.8V - 5V DC
  • Long-term max output current: 100mA; short-term peak: 150mA
  • High efficiency, low noise, and short-circuit protection
  • No-load input current: only 0.65mA
  • Compact design: 11mm x 7.62mm x 4.5mm (excluding pins), lightweight (approx. 0.5g)
  • Breadboard & MCU development-friendly 2.54mm pin pitch

Applications:

  • ESP8266 WiFi modules
  • HC-05, HC-06 Bluetooth modules
  • HC-11, HC-12 wireless UART modules
  • CC1101, CC2500, NRF24L01+ wireless chips
  • Low-power LED drivers

Usage Tips:

  • Ensure input voltage is within the 1.8V-5V range
  • Do not exceed 100mA output long-term, or 150mA short-term
  • Input power must exceed output power due to module power consumption

Ideal for powering IoT sensors, remote wireless modules, and battery-powered development boards where stable 3.3V DC is required.
