Speaker 0.5W 8 Ohm

The Speaker 0.5W 8 Ohm is a loudspeaker with an impedance of 8 Ω and a power rating of 0.5 W. It turns electrical signals into sound, so you can add tones, alarms, voice messages and music to Arduino, ESP32 and audio amplifier projects. It is a common match for MP3 player modules, voice recorder modules and small audio amplifier boards.

Speaker 0.5W 8 Ohm Specifications

• Impedance: 8 Ω
• Rated power: 0.5 W
• Type: dynamic loudspeaker (magnet and voice coil)
• Connections: 2 (positive and negative)

Speaker 0.5W 8 Ohm Applications

• Sound output for DFPlayer Mini MP3 modules
• Voice recorder modules such as the ISD1820
• LM386 and PAM8403 amplifier projects
• Alarms, doorbells, timers and talking robots
• Playing tones with the Arduino tone() function through a transistor

What's in the Box

• 1 × 0.5 W 8 Ω speaker

Tip: Do not connect the speaker straight to a microcontroller pin: 8 Ω on 5 V would try to draw over 600 mA. Drive it through a transistor or an amplifier module, or through a 220 Ω series resistor for quiet tones, and keep the amplifier volume low enough that the speaker stays within its 0.5 W rating.
