Graviton

Graviton 3.3V 16-bit ADS1115 4-Channel ADC Module

SKU CH-TWC1-XS0B4

A 16-bit, four-channel analog-to-digital converter module that operates at 3.3 V and communicates over I2C using the ADS1115 chip

  • 16-bit precision for accurate sensor readings
  • Four input channels let you monitor multiple signals
  • 3 V operation matches Raspberry Pi logic levels
  • I2C interface simplifies wiring and code

16-bit ADS1115 ADC for Raspberry Pi

This Graviton module adds four analog input channels to Raspberry Pi 3, 2, Model B and B+ boards via I2C. It operates at 3.3 V and provides 16-bit resolution for precise voltage measurements. The board suits hobbyists and engineers who need to read sensors or other analog signals directly.

Makers needing analog input on Raspberry Pi

Users who require more than four channels or higher sampling rates should consider alternative solutions. Projects demanding 5 V logic levels without level shifting will need additional circuitry. Buyers looking for built-in signal conditioning or programmable gain beyond the module's fixed specification should look elsewhere.

Highlights

  • 16-bit precision for accurate sensor readings
  • Four input channels let you monitor multiple signals
  • 3 V operation matches Raspberry Pi logic levels
  • I2C interface simplifies wiring and code

Questions about this item

What Raspberry Pi models does the 3.3 V ADS1115 module work with?

The module is designed for Raspberry Pi 3, Pi 2, Model B and Model B+ boards using the I2C bus.

Can I connect 5 V sensors to the four ADC channels on this board?

No. The ADS1115 runs at 3.3 V so input voltages must stay within that range to avoid damage.
