VCVS2

Eltvor's CubeSat-compatible OBC/DPU originating from our successful mission of dual camera. The board contains Zynq 7k CPU+FPGA SoC, connectivity to platform bus is via CAN and RS485. (I²C is populated as well, but not recommended.) Other connectivity includes: 1000BaseTx Ethernet, USB host port. Power consumption is around 1W. The DPU includes 4GB of eMMC non-volatile storage.

The DPU may directly connect 1 or 2 camera modules of our design, which was the original mission. In case of interest, Eltvor has these cameras ready, B&W and RGB (Bayer) versions, 1.3Mpix, 13eRMS readout noise, 10000e well capacity.

The DPU as well as the camera modules do have a flight heritage (photographing right now at 520km altitude), vibration & shock to Falcon-9 + ISIPOD profile, TID >=25krad (3 samples), T-vac.

Please see attached a brief specs sheet of the VCVS2 DPU.

The equipment offered:

The development environment for VCVS2 is standard ARM Linux. If camera option is selected, FPGA firmware is delivered including a C library and a standalone Linux executable which is able to shoot pictures in 1.3Mpix * 10b quality. In flight, we have successfully performed SW updates via CAN, JPEG2000 compression, automated image scoring and exposure control etc.
