Description

The XD-21 (LM358 100x Amplifier Module) is a signal amplification circuit based on the LM358 operational amplifier, used to amplify weak signals from sensors (such as sound, light, or analog sensors) so they can be easily read by microcontrollers like Arduino.

Features:
• Signal amplification up to 100 times (Adjustable Gain)
• Based on the low-power LM358
• Suitable for weak signals from sensors

Uses:
• Amplification of microphone signals or analog sensors
• Improving sensor reading accuracy in electronic projects
