VBUS(GP40, 우측 상단)에 연결하면 USB Host 모드로만 작동해야 한다는 의미 같은데
아마 USB device 모드라면 USB를 통해 전원을 입력받아야 하기 때문이려나?
Whilst it is possible to connect the Raspberry Pi’s 5V pin to the Raspberry Pi Pico VBUS pin, this is not recommended. Shorting the 5V rails together will mean that the Micro USB cannot be used. An exception is when using the Raspberry Pi Pico in USB host mode, in this case 5V must be connected to the VBUS pin.
GP0이 TX GP1이 RX
LED는 GPIO25에 연결되어 있고, TP5로도 연결이 되어있는데
BOOTSEL은 TP6에만 되어있고 GPIO로 연결은 되어 있지 않다.
TP1 – Ground (close coupled ground for differential USB signals) TP2 – USB DM TP3 – USB DP TP4 – GPIO23/SMPS PS pin (do not use) TP5 – GPIO25/LED (not recommended to be used) TP6 – BOOTSEL

동영상에서 본대로 해보니 되는데 일단은 ttyACM0을 sudo 없이 여는 법을 찾아봐야...(휠 설정을 찾아야 하나)
아무튼 rshell을 통해서 접속하면 /pyboard 라는 경로가 생기는데 이쪽으로 복사해야 된다.
USB 저장장소로 인식되는 건.. 펌웨어만 올리는 용도인가?

thonny 를 윈도우에 깔고 시작!
음.. initial settings에 standard와 raspberry pi가 있는데 일단은.. pico가 라즈베리일려나?
Switch to regular mode 버튼을 눌러보면
tools - options - general 에 가서 바꿀수 있다는데 라즈베리 파이 모드에서는 안뜨는 메뉴인듯
재시작해보면 달라지긴 한데..
UI만 달라졌을뿐 큰 차이는 없는 듯?
암튼 우측 하단에 Python 이라고 된 걸 클릭해서
MicroPython (Raspberry Pi Pico) 로 바꾸면 설정 끝
빈걸 저장 눌러보니 어디다 저장할지 물어보는데 "Raspberry Pi Pico"를 누르면
