MULTI-USE DIY BOARD
Introducing the MULTI-USE DIY BOARD!
This is a very useful board for audio / video switching, region select mods, overclock select mods, and many others!
STANDARD VERSION: $19.00 USD
PRO VERSION: $24.99 USD
note: button color may vary depending on supplier.
How it works:
This board lets you easily swap analog and digital signals (2 input select, 1 output or visa-versa) with the push of a button. You can also daisy chain these to switch even more things at once! It works great for a soft power-up as well. Finally, everything is nicely "debounced" meaning you get an accurate state change every time your finger hits the button. Check out my video explaining the functions.
The board features a resettable fuse for short-circuit protection and is very robust. Since this is not using microcontrollers, it is *very* hard to blow these chips up. They are lightning fast CMOS logic and consume almost nothing in power (<10mah for the entire circuit, most of that is the LEDs!).
The STANDARD version has ~100ohms between the common and the output of the switch. This means you will get some signal drop across it for analog. If using for video switching I recommend using an amplifier (such as TH7314) or buy the upgraded version.
The PRO version has only ~ 0.5ohms between the common and the output of the switch. This means a negligible signal loss. It also has a 4th extra switch!
