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:
- GPIO pins of the Raspberry Pi - to connect to the Raspberry Pi
- Analog I/O pins - screw connectors
- Analog inputs - connectors are compatible with sensors from Waveshare
- The resonator of 7.68 MHz
- Module LM285-2.5 - provides the volatge for A/C converter
- Photoresistor
- Information LED
- Potentiometer 10 kΩ
- The DAC8552 module - 2 channel, 16-bit C/A converter
- The LED indicating the power
- ADS1256 module - 8-channel, 24-bit converter of A/C (4 differential inputs)
- Test jumper of A/C converter
- Test jumper of C/A converter
- Jumper of voltage selection
- 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
