The Spresense mainboard, camera board, and the extension board can be purchased as a package.
This compact 5MP camera board has a Sony 5.11MP color CMOS sensor with a 2608 (H) x 1960 (V) resolution, which is placed on a compact board measuring 24.0mm x 25.0mm. It can be directly plugged into the Spresense main board with a ribbon cable and outputs in Y/C RGB RAW 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 78° FOV with an f/2.0 aperture and a built in IR-cut filter for more accurate color representation.
The Spresense LTE extension board adds LTE connectivity to the Spresense main board and carries an on-board antenna and a nanoSIM card holder. It also extends the interfaces of the Spresense main board with multiple mic inputs, headphone jack and microSD card slot.
The Spresense main board and the Spresense LTE extension board are connected by a board-to-board connector.
