Consider exposing a Reset feature

[Makuna]

"You can pull RST low level for 10 ms, and then pull it high, ( suggest 5V voltage)the module will restart read tags.if you plan to use 1pcs lipo battery, I suggest you can use MP1540 step-up DC-DC,3.7 lipo battery step-up tp 8V, and get best reading performance.no sleep mode, you can use mosfet to control power supply, when you don't need read tag, you can shut down the power."

At least add something to wiki

This is the answer from the guy that build the pcb
