3D Camera Module is a scalable SPI enabled 4 camera array pinout for 3D photogrammetry reconstruction which uses I2C to connect between each module to expand camera capacity while keeping capture sequences in sync. It uses ATMega32U4 with its built in USB 2.0 for data transfer and camera array adjustments and capture as well as a micro SD card slot for local image storage. An interrupt logic pinout should be used on the SPI master module as capture command. Each module is powered via USB-C (5V) or barrel jack (12V regulated to 5V).

The LIS3DH is a very popular low power triple-axis accelerometer. It's low-cost, but has just about every 'extra' you'd want in an accelerometer. This sensor communicates over I2C or SPI (our library code supports both) so you can share it with a bunch of other sensors on the same I2C bus. There's an address selection pin so you can have two accelerometers share an I2C bus.

Time-to-Digital converter plug-on module (shield) for Raspberry Pi B+. The board utilizes a TDC7200 (TI) with a time resolution of ~50ps. The Start/Stop inputs to the TDC can be configured with JP2 from either external signals or coming from the RPi's GPIO5 pin in case a timing signal is present at this pin from another plug-on board on the same RPi. Start and Stop signals can be configured from different signals (coming from the input connectors) or the same source (setting "common" on JP3) either supplied from the Start input connector or GPIO5. Read-out of the TDC chip is done through the RPi's SPI bus.
