Sense.CAM.P
Betamonochrome QVGA camera
An ultra-low-power machine-vision tile built around the PixArt PAG7920J3, a 320 × 240 monochrome global-shutter camera module with an integrated lens. It captures 8-bit RAW frames over SPI (30 fps as configured; the chip's 180 fps is a parallel-bus figure), with 3.0 µm pixels, a 71.3° × 53.7° field of view, and 64 dB of dynamic range. Configuration is over I2C. A proprietary on-chip motion-detection mode draws under 100 µW (compared to 760 µW for QVGA output at 15 fps) making the tile practical to leave always-on in a battery-powered system, with auto exposure and gain control, auto black cancellation, mirror/flip, windowing, LED strobe, and multi-sensor frame sync built in.

Application Notes
I2C address
when GPIO2 (pad 3) is left floating, the I2C address will default to 0x35. Pulling GPIO2 (pad 3) high will change the address to 0x25, while grounding pad 3 will set it to 0x40. The camera will also respond to general broadcasts on 0x60.
Pad Assignments
| Pad | Type | Function | Note | |
|---|---|---|---|---|
| 1 | ⏻ | GND | ||
| 2 | D | GPIO1 | LED strobe, frame interrupt, frame sync or external clock (one at a time); unused by the driver | |
| 3 | D | GPIO2 | I2C address strap, latched 30 ms after power-up: floating 0x35 (default), to VDDIO 0x25, to GND 0x40. The broadcast address 0x60 always answers too. | |
| 4 | D | I2C.CLK | ||
| 5 | D | I2C.DAT | ||
| 6 | D | SPI.MISO | ||
| 7 | D | SPI.CLK | ||

| 9 | D | SPI.MOSI | ||
| 10 | ⏻ | V+ | 1.8-3.3V; also the I/O supply (VDDIO) |
