Camera interface for nRF52840

Hello,

I would like to take a photo and send it via Zigbee to another on nRF52840. Just a single image that is around 600x480 sizes. What interfaces can I use for that purpose? There is no MIPI CSI-2 or DVP. Time delay and colors are not priorities.

Additionally, could you recommend any camera module for an embedded system?

Thank you.

  • Hi,

    you can take a look at OV2640 - it's a cheap sensor with hardware jpeg compressor (it will come handy when sending an image over a slow link).

    nRF52840 has no CSI, neither any DMA-controlled parallel interfaces, so you need a camera module with internal frame buffer and SPI interface (ArduCAM is what I know about).

    Edit:  here is a demo project for 52840 with ArduCAM.
