you can ask your supplier/seller for accurate datasheet, because different brand has different characteristics although the type is the same sla type

you can download here www.adafruit.com/datasheets/SFGDemoV2.0.rar

@@projectid7432 thanks however my ZA620 is not being recognised but its turning on.. i tried everthing the manual says about connecting the wires but still nothing. on the SFG it says "open device failed, please check the password and the device adress".

try this 1. swap your TX and RX pin 2. check your cable (it happen to me, the cable i used to connect arduino and fingerprint looking good but when i tested using multi-meter its dead wire) 3. try using arduino code to read your fingerprint, you can download the code and instruction in the adafruit page. some of my fingerprints did not work with the software but all my fingerprint module worked well using arduino code

@@projectid7432ALRIGHT THANKS A LOT

nope, it is different module.

I looked up the as5600 datasheet and it says 0.5mm - 3mm but it depends on the magnet, in case anyone else comes here with this question. I have this board but haven't tested it yet. Going to be testing it soon :)

Diametrically magnetised magnets or normal magnets

yes of course, but you have to remove/change the battery when it run out the capacity

@@projectid7432 Ok thanks 👍
