步驟如下：
1. 連接板子到PC
2. 進入DFU模式(按兩下RST按鍵，接著紅色LED會是呼吸燈狀態)
3. 執行如下命令

$ cd
$ arduino-cli sketch new blink
$ vim blink/blink.ino

#define LED_PIN 24

void setup() {
    pinMode(LED_PIN, OUTPUT);
}

void loop() {
    digitalWrite(LED_PIN, HIGH);
    delay(1000);
    digitalWrite(LED_PIN, LOW);
    delay(1000);
}

$ arduino-cli compile --fqbn adafruit:nrf52:feather52840 blink
$ arduino-cli board list
    Port         Protocol Type              Board Name FQBN Core
    /dev/ttyACM0 serial   Serial Port (USB) Unknown

$ arduino-cli upload --port /dev/ttyACM0 --fqbn adafruit:nrf52:feather52840 blink
    Upgrading target on /dev/ttyACM0 with DFU package /home/steward/.cache/arduino/sketches/8EF9686B888CFE74FB4FD09C190F7FDC/blink.ino.zip. Flow control is disabled, Single bank, Touch disabled
