  • If you use a +12dvc AC to DC adapter it could blow up your circuit BUT it will warn you.. ONCE
Here's what happened to me while using a similar version that looks identical called a YwRobot 545043 but was NOT LetGo’s HW-131 I just received yesterday and it does work well on a 9vdc adapter: You’re gonna get a kick outta this.. it’s been a while since I’ve done any Arduino kit building but I’m pretty well equipped .. or was 3 years ago. anyway I thought I’d start with the RF Nano & MPU 5060 accelerometer to laser gun controller project.. I didn’t get too far tho cause the MPU literally blew up.. I’d tested the RF nano a little by loading the blink sketch on it and changing up the timing .. that went fine from my PC on the end of a Mini usb cable but when the MPUs arrived.. I put both chips in a breadboard.. with one of these little YwRoom dual voltage regulators mounted on the other far end of the board. I wanted to be sure the VDC was 5.0 before connecting it to anything .. and it definitely was each time I re-attempted this saga below… but what I didn’t realize was on this model breadboard the two power rails only went half way down the board.. I soon figured that out and jumpered 5v and GND across the power rails horizontally and was finally ready to re connect to the chips. To my surprise when I turned ON this YwRoom regulator’s little switch the green regulator power LED came on and 5.02 VDC was there UNTIL I shut OFF then connected power this output +5dvc to the two components.. then when I turned it ON again the GRN LED was only blinking slowly at a .5second rate and VDC was reading 0.02 VDC.. so I shut it OFF disconnected the RF NANO’s power only, and turned the switch ON again and instant puff.. the tiny regulator on the MPU instantly caught on fire 🔥 and a ton of smoke and sparks billowed out of this little MPU 's regulator.. I figured I must have had a bad breadboard regulator… switching OFF the regulator switch and disconnecting it I tried again but with the two components disconnected.. and a new YwRoom regulator in place, the power was again 5 VDC on the rails but as I was careful to ONLY connect the RF nano alone this time (and the two to follow) .. when I did this the GRN LED on the YwRoom regulator started blinking again, I disconnected the nano leads and the regulator output to the rails had become +11.3vdc .. I tried a 3rd and it too blinked on PWR sw ON and upon re application of the power SW the VDC out to the rails was +11.34 VDC … way too high.. I’d been using the same wall-wort VDC supply earlier on a Geekcrit Arduino UNO with no problem but finally I tested its voltage out and noticed IT’s unloaded VDC out was +12.25.. much higher than the recommended 5 to 9vdc recommended on this YwRoom I later found out.. Bottom line I went thru 4 of these breadboard regulator puppies , ordered a batch of 6ea more replacements and a new wallwort that’s spec’d properly at 9 VDC and 1.5 amps out and since the Nano still runs blink ok on a Direct micro USB to PC cable.. I don’t know for sure yet… But it might have survived this cause the YwRoom blinking might be indicating .. “ I’ve fused open to protect you this time and BUT I'm now damaged and putting out + 11.34 VDC. So do NOT connect me to a load” … and tho I have 2 regulators and 2 Spare MPU 5060s left I figured after blowing 4 of these regulators that all now out out 11.3vdc.. I better get the proper wall adapter to drive the poor circuit before I try again. I’m very glad my wife was out of the house cause the magic smoke smell was really really bad for quite a while. No one seems to have mentioned this FAIL SAFE Fuse and LED blink behavior.. but my experience with 4 of them doing the same thing seems to suggest it does provide this WARNING .. but ONLY once sinse the next time its turned ON with a 12 vdc input connected .. the output seems to be +11.3vdc on the 5V rail. ... show more

  • Nice. Wasn't expecting USB-A for power in, it's 2023 for crying out loud.
They do the job, they're cheap. Had to make my own a->a cable to power it, but that's just practice. Heh.

  • So far no issues (SEE UPDATE)
I'll update my review if they start to burn up excessively quick, but for now there are no issues. I checked all 5 and they are giving proper 5.0v and 3.3v (plus or minus a tiny bit) outputs. I did not check the USB output as I don't need it for anything. One person reported they had several solder bridges, but all my boards look pretty clean. The only issue I saw were some of the pins were bent - but that's to be expected during shipping for these types of boards. UPDATE: The description states that the power supply can provide 700ma. However, at least using the 5v rail, I couldn't get above ~330ma before the voltage would drop. Not sure if you could get 700ma on the 3.3v rail as I didn't test it. But, I tried three different modules and they all dropped voltage around 330ma. Just an FYI. Also, one of the boards - within the first 5 minutes of use - the power button stopped working. ... show more

  • really helpful for multivoltage projects
I sure wish I started using these guys sooner! I use a lot of Arduino 5v boards, and nodemcu and wemos D1 mini boards, and these make it so easy. 3.3v boards, 5v sensors, and the level converters needed used to be such a rat's nest on the breadboard, but no more. It solders onto your PC project board too when it's time to put it in a case. These are just great! ... show more

  • Missing documentation
You can find the schematic online, but that didn't help me decipher how this board works. Here's the scoop: - the board is silk screened "HW-131", though Hiletgo doesn't refer to it that way - the barrel connector apparently must be attached to a 6.5-9V DC power supply. (If you connect the barrel connector to a USB power supply, the board will supply only either 3.3 or 2.5 volts, depending on your shorting pin placement.) - the USB connector is a power INPUT, which likely will require you to obtain a USB Type A male > Type A male cable, and obviously, a 5V USB power supply. - the 4-pin headers on each side of the board allow you to select the voltage for that half of the board; you can independently choose two voltage outputs. - the headers are labeled somewhat confusingly "5V OFF __ 3.3" (one pin has no label). - applying the supplied shorting pins across "5V" and "OFF" gives 5V out for that side of the board. - applying the supplied shorting pins across the unlabeled and "3.3" pins gives 3.3V for that side of the board. I'm happy with the product, but it's a shame Hiletgo can't list some simple instructions. ... show more

  • So handy for the hobbiest
These seem very sturdy and because they are HiLetgo, I trust that the electronics are safe and good quality. They attach well to the breadboard and don't take up much space. They are versatile, as you can have either 5V, 3.3V or both fed to the breadboard. They also have additional power pins that you can use without the breadboard. It's very handy to have the power switch, so you can just power things off right at the breadboard. The packaging is lacking some as some of the pins were bent when it arrived. I straightened them out and things are still working. It is a little worrisome that this may have created a weakness that will cause problems later on. The only disappointment I've had is that it consumes part of the power. I should have realized this. It turns out that I need 7.5V coming in to get a full 5V of output. After switching to a better power supply, I'm fully satisfied. I'd recommend this highly. ... show more

  • Works well but a jumper was missing
One of the boards was missing a jumper which is minor but unfortunate.
