The ADS1115 16-Bit ADC Module is a high-precision electronic converter designed to bridge the gap between real-world analog sensors and your digital microcontrollers. It is the ultimate upgrade for development boards that either lack analog input pins (like the Raspberry Pi) or require much higher accuracy than their standard built-in sensors can provide.

• Resolution: 16-bit high-precision accuracy (splits voltage into 65,536 steps)
• Channels: 4 Single-Ended inputs or 2 Differential inputs
• Interface Type: I2C communication (uses only 2 control wires)
• Input Voltage Range: 2.0V to 5.5V DC
• Sample Rate: Programmable from 8 to 860 samples per second (SPS)
• Onboard Amplifier (PGA): Up to x16 programmable gain for tiny signals
• I2C Addresses: 4 selectable addresses (allows cascading up to 4 modules together)

• Microcontroller Upgrade: Gives boards like the Raspberry Pi the ability to read analog sensors, and boosts Arduino voltage precision by up to 64 times.
• Noise Reduction: Differential input mode compares two signals to eliminate background electrical noise, giving you highly stable data.
• Low Power Consumption: Features a single-shot auto-shutdown mode that preserves battery life in portable or remote DIY projects.
• Tiny Footprint: Compact breakout board design fits easily into tight enclosures, breadboards, and custom project layouts.
