# Warnings (DY1Av2)

## Pin Conflicts

* When the Deneyap Camera is connected, do not make any external connections to the camera pins.
* While using the built-in addressable RGB LED, do not make any external connections to the **D9** pin.
* During code (firmware) upload, do not make any external connections to the **TX (D2)** and **RX (D3)** pins. After the upload process is complete, if you are not using these pins for UART communication, you may make external connections.
* If an external connection is provided via the I2C connector, external connections can be made to the **D10 (SDA)** and **D11 (SCL)** pins via an I2C interface with the same pin configuration; however, do not make any other external connections to these pins.

## Assembly

When removing your board mounted on a breadboard (prototype board) or a similar unit, be sure to carefully hold it by the edges as shown in the image to avoid damaging the USB port.

## Maximum Voltage for Analog Reading

Pins **A0, A1, A2, A3, A4, A5, A6, A7, A8 (BAT), D0, D1, D12, D13, D14** with **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**.
