The Spresense mainboard, camera board, and the extension board can be purchased as a package.
This compact HDR camera board has a Sony 1.84MP color CMOS sensor with a 1960 (H) x 960 (V) resolution, which is placed on a compact board measuring 28.0mm x 28.0mm. It can be directly plugged into the Spresense main board with a ribbon cable and outputs in Y/C, RGB and JPEG video formats over an 8-bit parallel data interface. Command and control are done through an I2C bus. This board includes a build in fixed focus lens that has a 50.3° FOV with an f/2.0 aperture and a built in IR-cut filter for more accurate color representation.
This extension board connects with the Sony CXD5602PWBMAIN1 main board and provides Arduino Shield based connectors, SD card slot, 4 analog/8 digital microphone header and a headphone jack. ISP, SOC and Processors, Sony, Audio input/output: 8 ch digital mic input or 4 ch analog mic input, headphone output | Digital input/output: 3.3 V or 5 V digital I/O | Analog input: 6 ch (5.0 V range) | External memory interface: micro SD card slot.
This main board includes both the Sony CXD5247GF and the CXD5602GG processor chips and includes an on-board GPS chip antenna, a camera interface, USB based 0debug interface and a 26-pin extension connector.
Several add-ons can be made or purchased to support additional features like LTE, WiFi, Bluetooth BT/BTE and image sensors.
