First brought to market in 1971, the 555 timer has been a staple in the electronics world ever since, and the Ramsey UT5 timer kit has always been one of our top sellers. The UT5 provided a quick and easy way to harness the power of the 555 timer IC - a valuable tool for any electronics hobbyist! But there is only so much you can do with the UT5 before you start running into its limitations. We knew people wanted a kit that would let them do more with the 555 timer, so to that end, we present the brand new UT5A series kit.
This new series builds on the classic UT5 kit, but takes it to a whole new level! We've packed it with tons of features that you won't find in any other 555 timer kit on the market. You can configure it on the fly with easy-to-use jumper settings, drive relays, and directly interface all timer functions with onboard controls or external signals. All connections are easily made though terminal blocks. Plus, we've replaced the ceramic capacitor of other timer kits with a Mylar capacitor which keeps your timings stable over a much wider range of voltages!
Then, to separate the hobbyist from the advanced hobbyist (or the wanting to learn more hobbyist!) we duplicated the through-hole UT5A in a surface mount (SMT) version! If you want to learn SMT construction, or polish up your existing SMT techniques while exploring the ever popular 555 timer, the UT5AS is for you! Just check out the comparison table to see how everything that's new and improved in the UT5A series!
