🛠 Camera CSI sur Zero v1.3 : le nappe 22 broches

Goal

Capture a still image from the Zero's CSI camera port — present only on revision v1.3 boards (revision codes 900093 / 920093). You will identify your revision, fit the correct flex cable, and shoot a 1920x1080 picture.

Wiring & parts

• A Zero v1.3: check cat /proc/cpuinfo (Revision line) — v1.0 has no camera connector at all
• Camera module + the short 22-pin, 0.5 mm fine-pitch Zero flex cable: a standard Raspberry Pi camera ribbon does NOT fit or work in this connector
• Mini-HDMI display if you want the live preview (optional)

Steps

# Enable the camera interface, then reboot:
sudo raspi-config    # Interface options -> Camera
sudo reboot

python3 - <<'EOF'
from picamera import PiCamera
from time import sleep
cam = PiCamera(resolution="1920x1080", framerate=30)
cam.start_preview   # requires the mini-HDMI display attached
sleep(2)              # let auto-exposure settle
cam.capture("/home/pi/capture.jpg")
cam.close
EOF

On newer OS releases prefer rpicam-still -o capture.jpg (libcamera).

Check

/home/pi/capture.jpg exists as a sharp 1920x1080 JPEG ; with the display attached you see the preview before the shot.

Pitfalls

• Standard camera ribbon in the 22-pin Zero connector: it simply does not work — buy the Zero-specific flex, and handle it gently (the FFC tears easily ; pull the latch straight up).
• v1.0/v1.2 boards have no CSI port: no adapter will conjure one.
• start_preview with no display attached: confusing silent failure — drop the preview when headless.
• 512 MB RAM: keep heavy image-processing pipelines off the Zero itself.
