# Warnings (DY1A)

## Pin Conflicts

* When the Deneyap Camera is connected, do not make any external connections to the camera pins.
* While an SD card is inserted into the built-in SD card connector, external connections can be made to the SD card connector pins **(D9, D13, D14, and D15)** only via an SPI interface with the same pin configuration; apart from this, do not make any external connections to these pins.
* When using the built-in addressable RGB LED, do not make any external connections to the **D12** pin.
* During code (firmware) upload, do not make any external connections to the **TX (D2)** and **RX (D3)** pins. After the upload process is completed, if these pins are not used for UART communication, external connections can be made.
* During code (firmware) upload, do not make any external connections to the **D8 (BOOT)** pin. After the upload process is completed, external connections can be made.
* If an external connection is provided via the I2C connector, external connections can be made to the **D10 (SDA)** and **D11 (SCL)** pins using an I2C interface with the same pin configuration; apart from this, do not make any external connections to these pins.

## Mounting

When removing your board that is placed on a breadboard (protoboard) or a similar unit, make sure to hold it carefully from the edges as shown in the image to prevent damage to the USB port.

## Maximum Voltage for Analog Reading

The **A0, A1, A2, A3, A4, A5, DAC1, DAC2, D8, D9, SDA, SCL, D12, D13, D14, and D15** pins, which have **12-bit** resolution, can be used as input pins for analog signals. These pins reach the maximum value of **4095** at approximately **3.15 V**.
