QUICK START GUIDE

1. Solder Q1, trigger coil-T2 and Xenon Flash tube the board if they are not populated.

2. Turn off the power supply.

3. Attach the positive terminal of the power supply (3V - 6V) to the VIN.

4. Attach the negative terminal of the power supply to GND pin.

5. Turn on the power supply.

6. Press “FLASH”-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

7. “ENABLE”-SW2 serves only as a toggle SW to start/stop the charge, no flash will be triggered.

8. SW2 works with SW3 to set the current limit

a.

use SW3 to program the current limit (see table for setting Bits 0-3)
