I don’t understand from the documentation how to switch from reading from the integrated antenna to the external one at the hardware level.
as mentioned in the hookup guide (Using an External Entenna - SparkFun Simultaneous RFID Reader - M7E Hookup Guide) you need remove the soldered zero resistor to the on-board integrated antenna and make a link to the connector for the external antenna
Hi @paulvha , do you have a photo of the new connection? I don’t understand what I need to solder after removing the resistor
The 0 ohm resistor is normally connected to the integrated antenna like this
After making the change to external antenna it will look like this
So the midpoint is the same, but instead connected 0 ohm resistor to the right, it is connected to the left.
On the M7E Sparkfun made it a “bit” more difficult, unless you have a professional soldering Iron. So soldering bridge with a small wire instead of 0 ohm resistor will do the job as well
