The default firmware requires that a FAT16 formatted microSD card be inserted into the microSD socket. After you turn the board on, the status LED will turn on signifying the board is ready to be triggered. If the LED starts blinking, the SD card failed to initialize and you should make sure it’s been formatted correctly.
Once the camera is triggered the board will capture a JPEG image and save it to the SD card. The file will be saved with a simple 3 digit number which is increment each time a picture is captured. While this happens, the status LED will start blinking. The camera can not be triggered again until the board finishes saving the current picture. After the JPEG Trigger has finished recording the image, the board will go back into the ready state and the status LED will go back to being solid. Each picture taken is saved as an individual 320x240 JPEG file. The files will actually carry the ‘.txt’ extension, but they are actually JPEG encoded, simply change the file extension to ‘.jpg’ in order to view them.
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. There is also a 6-pin header on board which mates with our FTDI Basic Breakout board for debugging or other purposes.
Note: This product does not come with the JPEG Color Camera or an SD card, you’ll need to purchase those items separately.
