This 8-channel, 8-bit analog-to-digital converter module adds extra analog inputs to microcontrollers and single-board computers through a simple I2C interface. Only four wires are needed (SDA, SCL, power, and ground), making it easy to read potentiometers, thermistors, light sensors, and other analog sensors.

• 8 analog input channels with 8-bit resolution
• I2C (IIC) SDA/SCL interface; two address pins allow up to 4 modules (32 channels) on one bus
• Sampling rate up to 70 ksps; supports single-ended and pseudo-differential inputs
• Supply voltage 2.7V to 5.25V with internal or external reference
• Compact board approx. 31 x 18 mm; operating temperature -40 to 85 C; pin headers included
