WWZMDiB 2Pcs ADXL345 3-Axis Accelerometer Sensor Module IIC/SPI Transmission Compatible with for Arduino GY-291 3D Printer Klipper

Excellent quality and exactly as described. It was packaged safely and securely, not only from physical damage but from electrostatic discharge and such things. As you'd expect for devices and chips like this. The price is very reasonable and it comes with 2 accelerometers. Both worked perfectly. Also included in the package was 2 sets of header pins to be soldered to the board and jumper wires with dupont connectors that were to short to be anything but inconvenient. I initially combined the wires for both devices to briefly wire one device and make see that it worked. So I'd advise figuring out what your going to need to hook these up and ordering it at the same time if you don't already have it laying around.That said, this is going to be a DIY project, but if you're ordering this you probably already know what you need to know to hook these up and use them. There are kits around that are already prewired or usb connected and some even have a mounting solution and they will cost a bit more but that would be what you should get if you can't solder and don't have any desire to tinker and build yourself.You can find this same device for cheaper across the ocean(wont name drop in this review but who floats like a butterfly and stings like a bee? get it?) also that inherently comes with at least 2 weeks shipping if not 2 months or more and the risk of it getting lost or never showing up is definitely a factor. Depends on your situation but for most it is going to make more sense to have this device at your door in a couple days, worry free, and only cost you a couple dollars more.I had no problem at all hooking both of these up to a rpi4 running klipper on an ender 3 v2. Soldering, wiring, hooking up, configuring in klipper took less than an hour and I was able to measure resonance frequencies of both x axis and y axis without having to move and remount as I would if I had just one accelerometer.Highly recommend

When I opened the bag the chip just fell off the board. Luckily it’s a two pack and the other was in working order.
