100W Digital Power Amplifier Board TDA7294 High Power Dual 12-32V Single Channel Audio Amplifier Module for DIY Speaker

The ADS1115 is a high-precision 16-bit analog-to-digital converter (ADC) module, engineered for accurate analog signal measurement in diverse electronic projects. It is fully compatible with STEMMA QT and Qwiic ecosystems, enabling easy plug-and-play integration without complex wiring. Equipped with 4 differential or single-ended input channels and a programmable gain amplifier (PGA), this module delivers outstanding performance for precise data acquisition, making it perfect for Arduino, Raspberry Pi, and other microcontroller-based DIY or professional projects. Boasting 16-bit resolution, the ADS1115 offers far higher precision than low-bit ADCs, ensuring minimal noise and accurate conversion of analog signals to digital data. Its programmable gain amplifier allows gain adjustment from 2/3x to 16x, enabling high-sensitivity measurement of small signal voltages (as low as ±256mV) and supporting larger voltages (up to ±6.144V) at lower gain settings. This flexibility makes it suitable for various sensors, including temperature, pressure, and light sensors. The module supports both differential and single-ended input modes for versatile measurement scenarios. Differential input effectively reduces common-mode noise, ensuring stable, reliable readings even in noisy industrial or outdoor environments. It also features selectable data rates (8SPS to 860SPS), letting users balance measurement speed and power consumption based on project requirements. With STEMMA QT/Qwiic compatibility, it has a standardized connector for tool-free connection to other compatible components, eliminating soldering and simplifying assembly. It communicates via the I2C protocol, using only two wires (SDA and SCL) to save valuable GPIO pins on microcontrollers. Featuring low power consumption and a wide operating voltage range (2.0V to 5.5V), the ADS1115 works for both battery-powered and mains-powered projects. Whether building a data logger, environmental monitor, or precision measurement device, this 4-channel 16-bit ADC module provides the accuracy, flexibility, and ease of use to realize your projects.
