Description

Module with high precision converter of A/C and C/A in the form of shield for GPIO connectors of Raspberry Pi. It has 2 16-bit analog outputs and 8 24-bit analog inputs. It communicates via the SPI interface. The board also contains a potentiometer and photoresistor connected to the input channels. It works with the Raspberry, version A+/B+/2B/3B.

The subject of the sale is only the converter.The Raspberry Pimust be purchased separately.

 

Specification
  • The connection through the GPIO pins of the Raspberry Pi
  • Built-in converters:
    • ADS1256 - 8-channel, 24-bit converter of A/C (4 differential inputs)
    • DAC8552 - 2-channel, 16-bit C/A converter
  • The module has goldpin and screw connectors

 

Connection

On the board are:

  1. GPIO pins of the Raspberry Pi - to connect to the Raspberry Pi
  2. Analog I/O pins - screw connectors 
  3. Analog inputs - connectors are compatible with sensors from Waveshare
  4. The resonator of 7.68 MHz
  5. Module LM285-2.5 - provides the volatge for A/C converter
  6. Photoresistor
  7. Information LED
  8. Potentiometer 10 kΩ
  9. The DAC8552 module - 2 channel, 16-bit C/A converter
  10. The LED indicating the power
  11. ADS1256 module - 8-channel, 24-bit converter of A/C (4 differential inputs)
  12. Test jumper of A/C converter
  13. Test jumper of C/A converter
  14. Jumper of voltage selection
  15. Configuration of the reference of the ground of the A/C converter - if the A/C is entered separately, AINCOM becomes terminal of the reference, it can be connected to ground or external power supply reference
