Equipped with the AR0234 global shutter image sensor, these new cameras provide sharp, motion-blur-free images, enhancing your capability to tackle high-demand applications effectively. Precision Imaging for Specialized Needs The C3-234 series is designed to meet the exacting demands of industrial automation, […]
Read MoreMatched cameras for the motorized zoom lenses
New motorized zoom lenses have irregular mount features for the cameras. We already had an IMX477 sensor-based MIPI CSI-2 camera for these lenses, but that was the only option till now. Almost all of the lenses have positive back focal distance, so in order to mount the sensor in the correct focal plane, a spacer […]
Read MoreEthernet camera module build log #5 – Automated flashing
Developing firmware for an embedded device requires a lot of testing. Processors capable of running full-featured operating systems are much more complicated than smaller controllers (but obviously also are more flexible). Some tests can be done on the host machine, but in most cases (especially related to specific peripherals), it is best to run tests […]

Buildroot is a simple, efficient, easy-to-use tool to generate embedded Linux systems. Allwinner S3 system can boot from: SD Card 0 / SDC0 SD Card 2 / SDC2 SPI NOR Flash / SPI0 SPI NAND Flash / SPI0 USB boot SD Card SOC checks each boot device in a sequence. If the boot step fails, […]
Read MoreEthernet camera module build log #3 – Network
Was debugging strange Ethernet behavior. The driver reported the opposite status of plugged RJ45 cable. It turns out I did not have a 100M RJ45 connector with integrated transformer and soldered 1000M by mistake. Good thing Würth Elektronik delivered new connectors very rapidly. And after a quick rework job network is alive! JBC C245-949 cartridge was very hadny to […]
Read MoreEthernet camera module build log #2 – X-ray day
I have a suspicion that my soldering skills are not good enough, and I don’t want to overheat the board by replacing SOC a third time. It means one thing – today is X-ray day! No shorts, soldering could be better, but overall looks ok. Ethernet still does not work. But now, when I know […]
Read MoreEthernet camera module build log #1 – Assembly day
After receiving fresh boards, it’s time to bring the Allwinner S3 CPU-based camera module to life. End even have some output on the console. It’s promising! USB and Ethernet does not work, though. Re-soldered S3 chip, and now USB is working. Ethernet is still dead.
Read MoreIMX477 camera board for motorized zoom lenses
With the introduction of motorized zoom lenses, the next logical step was matching the sensor board. Sure there are countless suitable sensors from various manufacturers like Sony semiconductors, Onsemi, Aptina, and many more. But lack of good support from the SOC side suggested starting from IMX477. It is a reasonably modern 12M image sensor used […]
Read MoreScrew-in optical filters
New screw-in filters for C and CS-mount cameras have been introduced on the Kurokesu e-store. Until now, filters were bare glass elements intended to be mounted during camera assembly or in case of camera rework kits installed with double-sided tape. For Kurokesu cameras, this was a somewhat limiting factor for a customer to change a […]
Read MoreNew motorized zoom lenses coming soon
Short announcement – it has been a few years since Kurokesu introduced motorized zoom cameras. So far there was a very limited selection, and it’s finally the time to grow the product line with lenses designed for larger image sensors. While cameras are still in development, only motorized zoom lenses and controllers will be supplied. […]
