Otherwise VCC will be powered directly from VIN and VIN-MAX=6V! 1. Solder Q1, trigger coil-T2 and Xenon Flash tube to the board if they are not populated. 2. Turn off power supply. 3. Attach the positive terminal of the power supply (3V - 6V) to VIN. 4. Attach the negative terminal of the power supply to GND pin. 5. Turn on power supply. 6. SW1 works with SW3 to set flash mode. a. Press SW1 once to trigger the flash sequencing. First, the microcontroller will enable charge for certain time and then trigger the IGBT to light up the flash tube b. Switch SW3 Bit0 to “1” to turn on flash mode c. Switch SW3 Bit1 to “1” will set the charge time to be about 12.8S +3.2S (if Bit2 is set to “1”) before flash d. Switch SW3 Bit2 to “1” will set the charge time to be about 3.2S +12.8S (if Bit1 is set to “1”) before flash c. Switch SW3 Bit”3” to “1” will set “red eye reduction” mode. The flash will be triggered for a few small pulses after the Co is charged up, and Co will be completely discharged by following flash. 7. SW2 serves as a toggle SW to start/stop the charge, no flash will be triggered. NOTICE: The information in this document is subject to change without notice.
