Replacement: None. We have a new revision that we’re working on, but it’s not yet ready and there is no ETA. There is no direct replacement for this board at this time. This page is for reference only.
The JPEG Trigger interfaces with the UART controlled JPEG Color Camera to simplify picture taking. To take a picture, all you need to do is ground either of the two external interrupts, which are labeled ‘0’ and ‘1’ on the board; a picture is then snapped and saved to a microSD card. The on-board ATmega328 is programmed to handle all the communication with the JPEG camera and the SD card.
The JPEG Trigger’s firmware creates a FAT16/FAT32 filesystem on any microSD card with a capacity of 4GB or less. Each picture taken is saved as an individual 640x480 JPEG file.
Power on the JPEG Trigger is regulated to 3.3VDC, and the on-board JST connector allows you to power the board via one of our LiPo batteries. We’ve broken the serial pins out to two headers - one is for connecting the JPEG camera, and the other mates with our FTDI Basic Breakout board for debugging or other purposes. We’ve also broken out a number of the ATmega328’s analog pins for custom use.
An RGB LED is populated on the board to show what state the Trigger is in. Here’s what the LED is telling you about the Trigger:
Note: This product does not come with the JPEG Color Camera or an SD card, you’ll need to purchase those items separately.
