Resistive burden & level shift to convert PZCT-02 Split-core Current Transformer output to ADC input voltages.
In searching for split-core current transformers, I ran across the PZCT-02. A rather inexpensive split-core 100 Amp transformer. Amazon AliExpress
This circuit provides burden resistance, voltage division & test point shifting to feed measurements into an Analog to Digital Converter (ADC).
I've used this with the 10bit analog input pins on Arduino's, as well as an ADS1115 16-bit ADC hooked to a raspberry pi I2C bus.
Both approaches work well. But I prefer the 16bit resolution on the I2C bus of the Pi, which can be polled rediculously fast using Collectd and the 'sensors' plugin.

Questions
How big is the PZCT-02-Burden PCB?
It measures 68 × 35 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PZCT-02-Burden use?
21 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the PZCT-02-Burden KiCad files?
From the bvarner/PZCT-02-BurdenShift repository on GitHub, at the commit this page was made from: the board is PZCT-02-Burden.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the PZCT-02-Burden design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
