The CJMCU-ADS1115 16Bit ADC Development Board Module is a high-precision analog-to-digital converter module designed for Arduino, Raspberry Pi, ESP32, STM32, and other microcontroller development platforms. Based on the Texas Instruments ADS1115 ADC chip, the module provides 16-bit high-resolution analog signal conversion for accurate sensor measurements and data acquisition applications.
The module supports four single-ended input channels or two differential input channels, allowing flexible analog signal measurement in various electronic and industrial projects. It communicates through the I2C interface, reducing the number of required microcontroller pins and enabling easy integration with embedded systems.
The ADS1115 features an integrated programmable gain amplifier (PGA) with adjustable gain settings up to 16x, enabling precise measurement of both small and large analog signals. It also includes an internal low-drift voltage reference and oscillator for stable and reliable conversion performance.
Designed for low-power operation, the CJMCU-ADS1115 supports programmable data rates from 8 samples per second up to 860 samples per second. The module operates with supply voltages from 2V to 5.5V, making it compatible with both 3.3V and 5V microcontroller systems.
This ADC development board is widely used in sensor interfacing, voltage monitoring, industrial automation, IoT systems, robotics, data acquisition systems, and precision measurement applications throughout Dubai and the UAE.
