I just got a QTPY RP2040 and I am unable to get the port to show the device. I tried installing the board but do not see it anywhere. I can see the QTPY SAMD21 but that board doesn't work. Any help would be appreciated. I am using the QTPY to hook up temp/hum and light sensor with an OLED all in I2C for a portable package. This will be used by students to gather data on experiments. ---

Hi @TrinityTeacher > [@TrinityTeacher](#): > > I can see the QTPY SAMD21 In this specific case, if you are seeing it somewhere in the Arduino IDE user interface, a [screenshot](https://www.techradar.com/how-to/how-to-screenshot-on-a-pc) of the IDE window might be helpful. > [@TrinityTeacher](#): > > that board doesn't work Please provide a detailed explanation of what you mean by this, including: - What did you do? - What were the results you expected from doing that thing? - What were the results you observed that did not match your expectations? - Make sure to include the full and exact text of any error or warning message you might have encountered. ---

Have you installed the board library for RP2040? As @ptillisch has said a screenshot would be helpful. RP2040 are 3.3v only to. Better off using a 5v board? Unless you are using this with careful students or have other circuitry. 🙂 🤔 ---

Thanks... Here is what I get when I search for boards. QT is not listed but the the rp2040 is. ![image](https://europe1.discourse-cdn.com/arduino/original/4X/1/4/8/148da8c32ff15bf68b90cefc395ef990da1b971d.png) ![image](https://europe1.discourse-cdn.com/arduino/original/4X/d/5/d/d5d935b9474cb3b67ba7204b858be728ec6efd15.png) ---

OK, it is clear now. I'll provide instructions for installing support for your "QT Py RP2040" board in Arduino IDE: 1. Select **File \> Preferences** from the Arduino IDE menus. The " **Preferences**" dialog will open. 2. Enter the following URL into the " **Additional Boards Manager URLs**" field of the " **Preferences**" dialog: ```plaintext https://github.com/earlephilhower/arduino-pico/releases/download/global/package_rp2040_index.json ``` ❗ If there are already Boards Manager URLs in the field, separate them with commas. 3. Click the **OK** button in the " **Preferences**" dialog. 4. Select **Tools \> Board \> Boards Manager** from the Arduino IDE menus. A " **Boards Manager**" dialog will appear. 5. Wait for the updates to finish, as shown by the messages printed at the bottom of the " **Boards Manager**" dialog. 6. Scroll down through the list of boards platforms until you find the " **Raspberry Pi Pico/RP2040**" entry. Click on it. Some buttons will appear on the entry. 7. Click the **Install** button on the " **Raspberry Pi Pico/RP2040**" entry. 8. Wait for the installation to finish. 9. Click the **Close** button on the " **Boards Manager**" dialog. 10. Select **Tools \> Board \> Raspberry Pi RP2040 Boards \> Adafruit QT Py RP2040** from the Arduino IDE menus. ---
