Things to check when using WizFi250-EVB (Arduino Shield)
summarize the items that must be checked to use WizFi250-EVB as a shield on the Arduino Board.

WizFi250-EVB is designed to also serve as an Arduino Shield.
Therefore, by connecting WizFi250-EVB to the Arduino Board, you can easily control WizFi250 from the Arduino Board.
Now, let's organize the things you need to check to use WizFi250-EVB as a Shield on the Arduino Board.
1. You must check whether WizFi250 operates in SPI Mode.
- Since the WizFi250 Arduino Library connects WizFi250-EVB (Arduino Shield) and Arduino using the SPI Interface, you must check the current mode of WizFi250.
- After factory default setting, WizFi250's mode is determined according to the first input interface signal. For example, if the first input signal is UART, it operates in UART mode, and if it is SPI, it operates in SPI mode.
- The method to factory default the WizFi250 is as follows.
In addition to using the Function Button, Factory Default can be performed using the Serial Command. (One thing to note is that no serial data should be transmitted after the Factory Default is serialized.)
2. Make sure the 0ohm resistance of WizFi250-EVB is in the position below.
If numbers 1 and 2 above are confirmed correctly, you can use the Wi-Fi function of WizFi250 after downloading the WizFi250 Arduino Library.
