A breakout board for the ADS1219 24-bit AD-Converter.
Size and pinout is the same as the popular ADS1x15 boards.
- Up to 1000Hz samplingrate
- Single or continuous conversion
- Single ended or differential inputs
pcb made with KiCad
Boards ordered from OSHPARK
If you want to use single-ended inputs, you should not use C6 and C7
I have written libraries for C and Python tested on a Raspberry-Pi
OM2220 wrote an Arduino library for it
and there is also one for micropython that I have not tested yet.
All libraries use the I²C-address 0x40 by default, so you have to connect the ADDR-Pin to GND, or use 0x41 in the constructor.
The ADS1219 has two address-pins A0 and A1.
A1 is always connected to GND, A0 has a pullup to VCC.
So the I²C-ADDRESS defaults to 0x41.
Four different addresses can be selected by connecting A0:
| ADDR connected to | Address |
|---|---|
| GND | 0x40 |
| VCC or open | 0x41 |
| SDA | 0x42 |
| SCL | 0x43 |
