The BOKRA I2C 4AI ADS1x15 Pro modules are professional analog input modules based on 16-bit ADS1115 and 12-bit ADS1015 ADC. Compatible with most types of microcontrollers (I2C interface is used to communicate with them).

The modules allow you to measure four differential analog signals, both voltage and current. The two ADCs installed on the module (either ADS1115-Q1 or ADS1015 from Texas Instruments) are 16 and 12 bits respectively. Type of ADC - ΔΣ (delta-sigma). Voltage measurement ranges: 0-0.5V, 0-5V, 0-10V, ± 0.5V, ± 5V, ± 10V. Current measurement ranges: 0-20mA, 4-20mA, ± 20mA, 0-40mA. Measurement speed: up to 860 measurements per second for ADS1115 and up to 3300 measurements per second for ADS1015.

mikroBUS modules can be installed on the BOKRA I2C 4AI ADS1x15 Pro modules, for example, BOKRA SoM Lite or Click® modules from Mikroelekronika.

Power supply: 9-36VDC. Isolation of the analog part of the module (1.5KVDC) and communication via the I2C interface, overvoltage protection and incorrect polarity are provided.

The BOKRA I2C 4AI ADS1x15 Pro module size 65 x 56 mm. The format of the module corresponds to the popular format of the Raspberry Pi 3A+, which greatly simplifies its use with the Raspberry Pi.

On the website of the manufacturer of the ADC - Texas Instruments - are some of the main applications:

  • Voltage and current monitoring
  • Transmission and other sensors
  • Factory Automation and Process Control
  • Battery control
  • Temperature measurement systems
  • Infotainment systems
