Is it possible to change the gain on an Adafruit PN532 board?
I need to LIMIT the range in order for it to NOT interfere with another PN532 installed close by.
The board is to be used with an Arduino.
I've looked through the Library but can't find any settings to change the gain. Also looked at other libraries forked from the original Adafruit lib.
I know that MRFC522 has some settings to control the gain, and I was hoping to find something similar with the PN532.

In the PDF there is a link to the schematics. It can be found here: https://cdn-learn.adafruit.com/assets/assets/000/009/729/original/PN532_Breakout_Schematic_v1.0.pdf?1374440547
