• Arduino MKR ZERO ($U1$): This is the central microcontroller board used in the project. It serves as the main processing unit for the shield.
• Winbond W25Q128FVPIQ TR ($U2$): This is a 128Mb flash memory chip that provides external storage. It's connected to the Arduino MKR using SPI communication.
• TF-015 ($J2$): This is a connector, presumably for interfacing with external components or devices, such as a microSD card.
• Resistors $R1$ and $R2$: These are 10k ohm resistors used for pull-up or pull-down functions, commonly used in digital circuits to ensure stability in signals.
• Capacitors $C1$ and $C2$: These provide power supply filtering and stabilization.

• Clock $CLK/SCK$: Connects to $U1:9\_SCK$.
• Data Output (MISO) $DAT0/MISO$: Connects to $U1:10\_MISO$.
• Data Input (MOSI) $CMD/MOSI$: Connects to $U1:8\_MOSI$.
• Chip Select $SS2$: Connects to control the activation of the flash memory chip.
• Other Nets: Include VCC and GND for power distribution, and other control lines for managing data transfer and memory operations.
