An open source point and shoot camera that cna be assembled with only a plain soldering iron.
This project came from my idea of trying to create a single board computer without touching any BGA chips. During my research talking with folks on the EEVBlog forum, someone pointed me to the Allwinner V3s microprocessor: it is a microprocessor in LQFP package, with 64MB DDR2 memory built in. This is definitely a win for this project, as I can solder this package without an oven.
This camera currently uses the OmniVision OV5640 image sensor, although any image sensor that uses the same MIPI CSI protocol and pinout should work with appropriate drivers.
- A 5MP camera with auto-focus.
- Connectivity options: wired Ethernet, 802.11b/g/n Wi-Fi and Bluetooth 4.0, USB 2.0 OTG, and a UART in another USB.
- Display: 4.3in 800x480 LCD, resistive touchscreen.
- Fully open source: hardware and software.
The primary components for this project includes:
- Allwinner V3s: ARM Cortex-A7 MP1 @1.2GHz, with 64MB DDR2-800 memory built in. The chip supports parallel LCD and MIPI CSI.
- X-Power AXP203: power management IC.
- Winbond W25Q256FV: 32MB NOR Flash for U-Boot, Linux kernel and root filesystem that contains the camera application.
- OmniVision OV5640: the camera.
- Realtek RTL8723BS: 802.11b/g/n SDIO Wi-Fi and Bluetooth module.
- microSD card slot. The card can be used for storing pictures, or booting the camera with custom U-Boot, kernel and root filesystem.
- Forlinx 4.3in LCD with resistive touch.
- XPTEK XPT2046: Resistive touchscreen controller.
- NXP SC18IS602B: I2C to SPI bridge (since I ran out of GPIO on the processor, and I need one SPI port for the touchscreen controller.)
