Ecarke Mini 4-Key OSU Keypad Hotswap One Handed Keypad Mechanical Gaming Keyboard,Can Self Programming Macro,with 1.5m USB-C Data Cable（Upgrade Cherry Shaft & RGB LED

When I first started to try to use this I was having what was most likely a software issue. I had no save option in the software, could not figure out why. I read over all the reviews of this product type and watched a few youtubes, someone had mentioned someplace along the line that his other keyboard was likely somehow interfering with the programming of this keyboard. I use an 88 keyboard and an additional numeric keypad, after I unplugged the mechanical numeric keypad all the problems with the software disappeared and it started working properly. I am using the version of the software that runs under chrome browser, you can also download it if you prefer. From the sounds of several things I read you can use this in a Mac environment but it might be a bit more difficult to deal with the software. In short, if you run the software and it detects more than one keyboard, you probably have a conflict. I had never heard of sayobot before but it appears they might make quite a few keyboard type products, thus the possibility of conflicts. This unit has two different usb c ports on it so you could orient it vertically or horizontally. What you basically get is the hardware to hold four three pin keyboard switches (the switches are removable) and a usb c to A cable. It comes with squishy red switches, I prefer clicky switches so I bought myself some clicky blue water resistant switches that I'll probably swap into it when they arrive. This uses standard keycaps so if you have an old keyboard laying around that doesn't work you could steal the keycaps off it and install them on this. You can also buy stick on labels or even use a sharpie to mark the keycaps if you wish. I have a bad disk in my back but I like to play my mmo games, I use this keyboard and program common keys to make it easier to run my game. For instance I have Tab to change targets, B to choose closest target, and E for attack button and the fourth button I currently have programmed for interactions F this is a lot easier on my left hand since I don't have to stretch across the keyboard to reach the keys during combat etc. The lights also work well, I like to use Breathing with random colors. I tend to play in a somewhat darkened room so I like the lighted keys. This tiny keyboard has some nice rubber feet on it so it does not slide around on my desk. I just ordered another product like this with more keys not sure what I want to do with that one yet but I could probably program attack powers for my Bard in Ashes of Creation or something along those lines. What's important to note is that you can plug in as many of these as you want and they will not fight with each other or your main keyboard. I think this just might be the best idea I ever had for dealing with my nerve issues in my left hand. The software at least under windows is pretty obvious. Plug in the keyboard, open chrome browser and click on the web link, it will give a detect button which should see the keyboard no problem and may offer you a firmware update option I updated the firmware but don't know if I really needed to do that or not. From there, there are a bunch of options, if you look around the web and on youtube there are some basic videos and instructions for setting up stuff like passwords programmed into a key. A lot of that stuff is a bit more difficult to learn and not what I wanted this for but heck have at it, it's nice to know the function is there even if I'm not using it. I'm simply using default which then opens up a keyboard graphic and you click on the button you want it to be, then you should get a Save button bottom left of the screen if you don't get the save button you may have a hardware conflict with another keyboard like I had. Lights are set similarly but you do it from the main screen there are quite a few choices of lighting type and colors, I just picked breathing and random color for a nice choice. When you change something don't forget to hit save or it won't be programmed into the keyboard. Now you can put this keyboard on any machine and it will keep the programming. I hope at some point they might upgrade their instruction sheet to mention the possibility of a conflict with another keyboard, that one had me cursing some bad words until I figured it out. I have three of these products now this one, a 8 key and I just ordered a 24 that's coming from china, this is the only one that has the two usb c ports that is a great feature that I wish they all had because it makes easier to use the keyboard vertically instead of horizontally if the cable plugs into the top/bottom instead of the side when oriented vertically. I prefer clicky blue switches to the squishy reds they give you with this one but they're very easy to change and not expensive so change away if you want to. You can buy different types of keycaps or even ones with a top that opens so you can put your own slip of paper inside to mark the key function. There are also sets of stick on key cap letters on amazon and other places or you could just go low tech and use a paint pen. Working great, easy to use. Note/Update: You may have difficulty using usb A to C cables other than the one that came with it. I've tried half a dozen shorter cables because I don't need such a long one and none of them transmit the key presses, the keyboard lights up but keys do not respond and the software can't see it when the keyboard is plugged in. So be aware there may be something non standard about the cables that come with these, mark them accordingly so you can locate them. If I find out what the difference is I'll post.

Used this for a raspberry pi project, where I needed a small number of buttons on a wired remote. These come pre-programmed as the keyboard numerals 1 through 4. No drivers, just shows up as a keyboard. They do have an app you can use to change the keys that are output, but I left them as 1-2-3-4 and just changed my raspberry pi code to accommodate. Good build quality. Wish the USB connector was at the top or bottom instead of the side.

Two minor issues: Came with the wrong cable, but that was easily resolved - keyboard updated to USB-C, but cable was micro USB. I had plenty of adapters and spares. Programming software had to be downloaded from a sketchy Chinese website, but it passed scans. Software itself triggered alarms, but only because of how it works - connects to the device via insecure web interface. Interface is pretty raw, and there's no documentation, but for what I wanted to do (add buttons to a kiosk to load voice recognition and on screen keyboard), it was easy. Only remaining problem appears to be with my PC - it occasionally "loses" the device when it falls asleep; unplug/plug resolves.

Super easy to program. This keypad will save me so much time entering my long 16+ character codes I do on a daily basis! Love it!

The lil' keyboard is cool as heck, the only downside is having to go to a certain website to change the settings for it, but otherwise it works great, and is great if you want to deafen or mute on discord quickly!

it came with a micro usb cable but uses usb-c. super annoying since i dont have usb-c cables for it. also misleading because the picture shows a cable with it as if its gonna be the right one as it should be. cool pad though the keys feel good, just wish the cable was right

For some reason the keypad has an input for USB c on the long side, but on the short side a USB micro. The cable they provide is USB c. I set it all up to use in the vertical position only to realize it's an incompatible cable. Not sure what the reasoning was on having two different input types based on orientation. Would be nice if the company fixed that, or at least sent a cable for each type so we have the option.

I’m using two of these and two six key pads for music making. Responsive and feels good under fingers.

I received a defective product, randomly disconnected, hard to use. It's easily moved, even with the bottom padding, on a desk mat/mouse pad (perhaps if there were some kind of extra weight this could be avoided?). The shafts are a bit "loose" to hold the keycaps, so there is some wobble (maybe this is intentional?). This had high potential, but the product quality is EXTREMELY DISAPPOINTING, especially since these 4 keys costed about 25% of my hot-swap tri-mode TKL. Still usable, but definitely considering a return. (In case you're worried, the software is NOT spyware/malware.)
