Good Functional Product, Met My Needs
For Breadboard + Power Supply + Jumper Wires
Glad to receive the breadboard (we can always use yet another am-i-rite?) and power supply. It arrived in a reasonable period of time. I wasn't in a big rush, so it got to me before I started wondering where it was, and exactly in time for a new project that had me disassembling another breadboard.
The PCB was rather grimy and needed a good alcohol clean-and-dry. Not sure what the grime is (maybe a no-clean flux?) but dealing with power, I didn't want potential contaminants adding noise or reliability issues.
The push-on/push-off switch has a rather unreliable action - it often won't pop-up into the power-off position. It improved a bit with the alcohol clean-up but still sticks a bit, so the vendor might look into a different device there.
The USB jack takes an old Type'A' plug - I had assumed it would use a mini or a micro. No big deal - in fact probably good in that it will let me use one of my old, now unused cables for something productive.
Final comment is that regulator has a lot of drop-out. I haven't looked closely at the circuit, but even supplying a 5V input on the barrel jack, it was unable to meet the 3.3V rail, topping-out at about 2.6V. With a 9V supply, I get a good solid 3.3V and 5V so that's good. An LDO regulator might be appropriate for a next revision. (The description indeed does say 6.5V minimum which I hadn't noted before I hooked it up - so my fault).
So all that said, it's a decent and useful product for a reasonable price. Hope the feedback is helpful for future improvements. Thanks for product!
