Description

The Soldered ADC 24-bit ADS1219 4-channel with PGA breakout adds precision analog measurement to any I2C host. Built around the Texas Instruments ADS1219, a 24-bit delta-sigma converter that samples at up to 1000 SPS with each conversion fully settling on its own, it reaches up to 20 bits of effective resolution at slower data rates. This provides quiet, clean readings usually expected from a much larger instrument. Whether you're logging sensor data, building a battery tester, or reading a load cell, this compact 22 × 22 mm board handles the measurement and sends the result directly to your NULA board, Arduino, or any other microcontroller over I2C.

One star less due to the difficulty to change the I2C address. The PCB color is nice until you have to cut a trace (yes, I'm not young anymore and my eyes are old, too). Furthermore the address change solder pads are too small for a simple solder blob, you have to use some copper to get the connection done.
Otherwise, at least for the digital side as I couldn't test the analogue part as yet, the device works ok and as expected.

I picked up the Soldered ADC 24-bit ADS1219 breakout for a load cell project, and it delivers impressively clean readings. Despite its compact 22 × 22 mm footprint, this board gives you up to 20 bits of effective resolution at lower data rates, providing quiet measurements you'd expect from a much larger instrument. Setting it up over I2C with my Arduino was straightforward. It samples at up to 1000 SPS with each conversion fully settling on its own, making it a fantastic choice for precision sensor logging or battery testing.
