flash module

This is a flash sold by a certain Wang family, and a microcontroller is used to light it.

The main control chip of the flash is AS3636, which uses I2C communication. Useful control pins: SCL/SDA/INT (interrupt)/STROBE (trigger)

Connector: DF23C-10DS-0.5V. If the microcontroller model cannot be found, you can use STC15W408AS to replace it.

There is an LED fill light next to the xenon lamp, and the brightness can also be controlled using AS3636. Through the configuration register, the brightness of the LED fill light, xenon lamp charging time, current, etc. can be controlled.

The size of the PCB board has been calculated and can be used to fix the flash:

In addition, the battery can be used as a small flashlight, and the buttons can control the brightness and trigger the flash.

Please see the attachment for the program DEMO. The video shows a flash cycle after fill light. There is no button function. The program needs to be modified by yourself.

You’ve seen this, why don’t you collect it and make one? Just give me a like and leave (*╹▽╹*)
