JOY-IT ADS1115 16-Bit ADC Converter Board, I2C, 4-Channel

The JOY-IT ADS1115 is a compact 16-bit analog-to-digital converter board built around the Texas Instruments ADS1115 chip. Unlike many basic ADC modules, it offers a programmable gain amplifier and four selectable I2C addresses, making it easy to stack multiple boards on a single bus for expanded analog input capability.

Highlights

• 16-bit resolution with four single-ended or two differential input channels
• Programmable gain amplifier with six ranges from ±0.256 V to ±6.144 V
• I2C interface with four selectable addresses
• Wide supply voltage range: 2.0 V to 5.5 V DC
• Low power consumption: 150 µA in continuous mode, 1 µA in single-shot mode

In daily use

The ADS1115 connects directly to Arduino, Raspberry Pi, ESP32, and other microcontrollers via its I2C pins. The onboard ADDR pin allows address selection, while the ALRT/RDY pin can be configured as a data-ready or comparator output. Its through-hole design fits breadboards and prototyping setups.
