7Semi ADS1015 12bit 4-Channel ADC Board with PGA I2C

The 7Semi ADS1015 12-bit 4-Channel ADC Board with PGA (Programmable Gain Amplifier) is a compact, high-precision analog-to-digital converter module based on the Texas Instruments ADS1015 IC. It provides four single-ended or two differential analog input channels with 12-bit resolution and an integrated programmable gain amplifier for signal scaling. Communication is handled via the I²C interface, making it compatible with a wide range of microcontrollers. Ideal for sensor interfacing and voltage measurement, this board is perfect for embedded systems, IoT applications, and data acquisition projects.
