Hello guys,
According to the "Simultaneous RFID Tag Reader Hookup Guide", I see on page 12 there is a footprint with holes to solder "a 2mm JST connector or a 3.5mm screw terminal", in order to connect a 3.7V LIPO battery.
On the board, I can see 4 holes, with a mention "3.7-5V". Does it mean I can solder a connector (screw terminal or other) on the 2 largest holes, and use them with a 5V USB external battery ? Are there 2 holes for 3.7V, and 2 others for 5V, or is it possible to supply 3.7V or 5V whatever the couple of holes I use ?
Thanks for your help
