UMLIFE 3pcs AS5600 Magnetic Encoder High Precision Sensor Module, 12bit, I2C, PWM, Voltage Output, Non-Contact, 23x23mm

I saw there were some negative reviews or at least comments about it not working with PWM out of the box. Makes sense, and I'm glad one reviewer pointed out how to remove the R4 resistor to make that work. For me, I typically use the AS5600 magnetic encoder using the I2C protocol on Arduino, and so for my application(s) I wasn't interested in PWM. This worked out of the box without any modifications for me, and this ready-to-go board is a huge time saver instead of buying the individual AS5600 chip and soldering the pins to capacitors yourself. Here's how you do it: 1) Connect Vcc to a power supply between 3.3V-3.6V or 4.5-5.5V, e.g. the 5V or 3.3V pin on your Arduino Uno. (if you look online for the AS5600 datasheet, you'll see it supports 3.3-3.6V and 4.5-5.5V, depending on how you connect the capacitors. However, this board has capacitors mounted in such a way that you can go either way! I tested it and it does work with both). 2) Connect GND to the ground of your power supply (or Arduino Uno, for example) 3) Connect the SCL pin to your Arduino's SCL pin, and the SDA pin to your Arduino's SDA pin. These are labeled on the Arduino Uno. On other boards, you'll need to look online for your board's pinout diagram to see which pins are for SCL and SDA. 4) Download a library for the AS5600. A good one is: google "as5600 arduino seeeduino", you'll find a result on the seeedstudio Wiki page for a Grove 12 bit magnetic rotary position sensor (AS5600). On that page is a link to "Download the AS5600 library from github" Download and install that library to your computer, and run the "readAngle" example by opening up your Arduino IDE and clicking File->Examples->Seeed Arduino-Master->readAngle. You should be able to bring a magnet (such as the one included in the package) close to the sensor and using the Serial monitor, you'll see the angle change as you rotate the magnet. Hope this helps anyone else out thee.

Just be aware that the magnet is tiny and very very easy to loose, and if you haven't used magnetic encoders before, know that the magnet needs to be extremely close to the sensor (the black chip), and these magnets are special, you can't just use any.

Removed R4, got a perfect triangle wave on the analog output at 3.3VCC. Looks very linear. Positioned the magnet on the motor shaft, and then put the encoder a couple mm above. The output looked great.

DO NOT USE 5Volts on these devices. They will stop working after a few minutes. Use Only 3.3 Volts and for Micros that are 5volts you will need to use a level shifter for the SDA SCL or any Digital Pins on the device./

Works great, buttery smooth encoder, all boards worked, all items provided (magnets) can place magnet in a vertical or horizontal position.

I had to remove the R1 and R4 resistors and use 5vdc input to get the described analog output on out pin. I2C still works fine with the resistors removed. It may be that only one of R1 or R4 needs to be removed, but I didn't try that. With that change I was able to see a very consistent 0-5 vdc change that corresponded to 0-360 degree rotation. 90 degrees was 1.25 vdc, and 180 degrees was 2.5vdc, and 270 degrees was 3.75 vdc. right at 0/360 degrees, the voltage changed from 0 to 5 vdc. Now very happy.

These work great, but they are wired for I2C ONLY! If you are looking for analog output, you will need to REMOVE the resistor which is connected to the PG0 pin (pin #8). then you will get an analog voltage output, at the out pin on the board. Without this, the output voltage will always be at Vcc (3.3 or 5V). Hope this helps someone....otherwise, they work great!

The images show the magnet included as a 6mm magnet, which is the one recommended by the manufacturer. The magnet received is a 4mm magnet which doesn't meet the specifications. Seller should remove listing or update with actual images of the product they're selling. In the image you can see the obvious difference in size.
