Hardware connection
Please take care of the direction when you connect Pico, an USB port is printed to indicate. You can also check the pin of Pico and the LCD board when connecting.
You can connect the display according to the table.
CAN Board | Pico | Description |
VCC | VSYS | 5V Power Input |
GND | GND | GND |
GP0 | TXD0 | UART TX (default) |
GP1 | RXD0 | UART RX (default) |
GP2 | CFG | CAN mode switch |
GP3 | RESET | CAN module reset |
GP4 | TXD0 | UART TX (optional) |
GP5 | RXD0 | UART RX (optional) |
Setup environment
Please refer to Raspberry Pi's guide: https://www.raspberrypi.org/documentation/pico/getting-started/
Download Demo codes

Python codes
Use in Windows
- 1. Press and hold the BOOTSET button on the Pico board, connect the Pico to the USB port of the computer through the Micro USB cable, and release the button after the computer recognizes a removable hard disk (RPI-RP2).
- 2. Copy the rp2-pico-20210418-v1.15.uf2 file in the python directory to the recognized removable disk (RPI-RP2).
- 3. Open Thonny IDE (Note: Use the latest version of Thonny, otherwise there is no Pico support package, the latest version under Windows is v3.3.3).
- 4. Click Tools -> Settings -> Interpreter, and select Pico and the corresponding port as shown in the figure.
- 5. File -> Open -> the corresponding .py file, click to run, as shown in the following figure:

Arduino IDE Series
Install Arduino IDE
-
Download the Arduino IDE installation package from Arduino website.
-
Just click on "JUST DOWNLOAD".
-
Click to install after downloading.
-
Note: You will be prompted to install the driver during the installation process, we can click Install.
Install Arduino-Pico Core on Arduino IDE
-
Open Arduino IDE, click the File on the left corner and choose "Preferences".
-
Add the following link in the additional development board manager URL, then click OK.
https://github.com/earlephilhower/arduino-pico/releases/download/global/package_rp2040_index.json
Note: If you already have the ESP8266 board URL, you can separate the URLs with commas like this:https://dl.espressif.com/dl/package_esp32_index.json,https://github.com/earlephilhower/arduino-pico/releases/download/global/package_rp2040_index.json
-
Click on Tools -> Dev Board -> Dev Board Manager -> Search for pico, it shows installed since my computer has already installed it.
Upload Demo At the First Time
-
Press and hold the BOOTSET button on the Pico board, connect the Pico to the USB port of the computer via the Micro USB cable, and release the button when the computer recognizes a removable hard drive (RPI-RP2).
- Download the demo, open arduino\PWM\D1-LED path under the D1-LED.ino.
-
Click Tools -> Port, remember the existing COM, do not need to click this COM (different computers show different COM, remember the existing COM on your computer).
-
Connect the driver board to the computer with a USB cable, then click Tools -> Ports, select uf2 Board for the first connection, and after the upload is complete, connecting again will result in an additional COM port.
-
Click Tool -> Dev Board -> Raspberry Pi Pico/RP2040 -> Raspberry Pi Pico.
-
After setting, click the right arrow to upload.
- If you encounter problems during the period, you need to reinstall or replace the Arduino IDE version, uninstall the Arduino IDE needs to be uninstalled cleanly, after uninstalling the software you need to manually delete all the contents of the folder C:\Users\[name]\AppData\Local\Arduino15 (you need to show the hidden files in order to see it) and then reinstall.
