MH Breadboard Power Supply Module — 3.3V / 5V, USB & DC Jack

MH Breadboard Power Supply Module — 3.3V / 5V, USB & DC Jack

The MH breadboard power supply module provides selectable 3.3V or 5V regulated output to both breadboard power rails. Accepts input from a USB port or 6.5–12V DC barrel jack. Each rail can be independently set to 3.3V or 5V via jumper — ideal for mixed-voltage Arduino and sensor prototyping setups.

Key Features

• ✅ 3.3V / 5V selectable per rail — independent jumper selection for each power rail
• ✅ Dual input — USB (5V) or DC barrel jack (6.5–12V)
• ✅ 700mA output — sufficient for Arduino, sensors and modules
• ✅ Powers both breadboard rails — + and − rails on both sides
• ✅ Power LED indicator — confirms power is on
• ✅ RoHS compliant

Key Specifications

• Output voltage: 3.3V or 5V (selectable per rail)
• Output current: 700mA max
• Input: USB (5V) or DC jack (6.5–12V)

Typical Applications

• Arduino breadboard power supply
• Mixed 3.3V/5V sensor and module prototyping
• Electronics classroom power supply
• ESP8266 and ESP32 breadboard power
