步驟如下:
1. 連接Nano33BLE板子到PC
2. 執行如下命令

$ cd
$ arduino-cli sketch new blink
$ vim blink/blink.ino
void setup() {
    pinMode(LED_BUILTIN, OUTPUT);
}

void loop() {
    digitalWrite(LED_BUILTIN, HIGH);
    delay(1000);
    digitalWrite(LED_BUILTIN, LOW);
    delay(1000);
}
$ arduino-cli compile --fqbn arduino:mbed_nano:nano33ble blink
$ arduino-cli board list
    Port         Protocol Type              Board Name          FQBN                        Core
    /dev/ttyACM0 serial   Serial Port (USB) Arduino Nano 33 BLE arduino:mbed_nano:nano33ble arduino:mbed_nano

$ arduino-cli upload --port /dev/ttyACM0 --fqbn arduino:mbed_nano:nano33ble blink

完成
