Get these right
- The cell is a round 18650, 66 × 18 mm, with a JST-PH 2.0 lead. Not a flat LiPo pouch.
- Check the lead’s polarity against the + mark on the Lipo Rider. Many leads are wired the other way round.
- Take the lens off the camera module. Your Super 8 lens focuses straight onto the sensor.
- The Pi needs a header. Solder one on, or buy the Zero 2 WH.
