Yongnuo YN560-IV Speedlite Wireless Camera Flash Teardown and Analysis
Engineer and artist Æva does a teardown on a Yongnuo speedlite flash, with some good pointers for miniature screw placement and removal, along with an analysis of multiple PCBs contained inside the unit, including high-voltage components, TI ICs, op-amps, and more.
I wanted to know what sort of trouble I was going to get into with hacking this flash so I did the natural thing and took it apart! This is the first teardown I’ve documented so it won’t be perfect, but learning opportunities are neat.
One juicy tidbit I took out of this is that the external high voltage connection feeds directly to the power supply board through a decidedly less esoteric connector. You can see it on in the middle of the top view of the power supply right between the cap and the transformer. Within a matter of minutes I found a few candidate mates for this 1.25mm detent locking connector.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
