QMC5883P
Could not get this thing to work Initially, The chip is marked as HP5883 which means that this is the QMC5883P not the L. Use the adafruit QMC5883P library

NOT HMC5883L
Completely misleading labelling. This is actually a qmc5883p. If you zoom in on the main chip it says "hp 5883 xxxx" which is the qmc NOT hmc. If the labelling is correct this is very good value for money. 3 magnatometer and some spare wires. Hope this helps for anyone else trying to get this to work

NOT an HMC5883L
Non functional - For starters these are not HMC5883L but a QMC5883P I’ve checked the pinout of the HP 5883 5503 on a datasheet and the silkscreened pinouts on the board appear to be correct, but despite trying many libraries have been unable to get it to communicate and it appears to crash the serial bus when used in conjunction with another device.
L**E
Not actual HMC5883l.
As the title says. They are actually QMCs. They still work but a deliberately misleading image/ item title to trick you into thinking they are HMCs
G**F
Not usable
Unable to get this module to work with any potential Arduino library after much research.
A**S
Do not work, useless
Did not work, they aper to be neither QMC5883L or HMC5883L absolutely not compatible with Pi Pico
