For microcontrollers without an analog-to-digital converter, or when you need a more accurate ADC. We provide Grove – 4-channel 16-bit ADC(ADS1115), a 4-channel ADC based on Texas Instrument ADS1115, which is a high-precision, low-power, 16-bit ADC chip. It supports 4 single ended inputs or 2 differential inputs. What’s more, it has a programmable data rate range from 8 SPS to 860 SPS with an internal programmable gain (up to x16) for small signals.

The module also contains a Grove port that is internally connected to its channel 0 and channel 1, of which makes it easier to use with Grove Ecosystem.


  • Wide supply range: 2.0V ~ 5.5V, support 3.3 or 5V system
  • 16-bit high resolution ADC
  • Programmable Data Rate: 8 SPS to 860 SPS
  • Internal Programmable Gain: x16 with Internal low-drift voltage reference and oscillator
  • The built-in PGA is gain-adjustable and can be controlled by software
  • 4 Single-Ended Inputs or 2 Differential Inputs
