Connecting the SRTR (M6E nano) with Arduino Uno without using it as a shield

Components & Accessories Power

I am working with the SparkFun Simultaneous RFID Reader - M6E Nano.

[https://www.sparkfun.com/products/14066]

I have connected it using it as a shield to read tags but now I want to connect it with the Arduino Uno using loose wires. From what I have looked up, this can be done by connecting

Nano GND to GND

Nano VCC to 5V

Nano TX to pin 2

Nano RX to pin 3

But now I am unsure of the position of the HW-UART/SW-UART switch. I noticed that the SparkFun Arduino sketches require the switch to be in SW- UART.

I have soldered the board as described in the SparkFun Hookup guide. I have not cut any jumpers and plan on powering the device using a 5V wall adapter connected to the Arduino Uno barrel jack.

Would any appreciate any help with this.

In this setup the switch position is not relevant. The TX and RX of the serial connector are connected outside the switch.

Thanks for your response.

Would I be able to connect to the Uno with the same setup when using the pins on the RFID shield instead of the serial pins?

I do not understand your question. If you set the switch to SW-UART the shield will use pin 2 and 3, it set to hW-uart it will use RX and TX (same as the USB is using)
