“4 stars unit ok // But use these a lot of wavshare products all stuck on HEX42 waveshare unresponsive to have addess select ''i chinnky not understand you reply '' ,,they not made by them by look f it ,, took weeks to sort out intermittnt errors on channel3 cos there UPS unit use hex 42 ...having to lift pin A1 of ic,s on replacments boards then legs break off”
“as to Waveshare......
this second time on this product// of selling same FIXED hex addess on your boards//and 1mm screws to fit your4mm holes on your boards and you waveshare need get your act together/ this posted also to your supplier pihut”
“updated the stars to 3 on this //last board had to lift pin1 and hard wire for next 4 address
this board had lift pin 2 for next batch addresses but the calibration on the in219 is
easier, so gave it a extra star ,,and ok on 12 addresses now”
“2 stars this time last one i had 4 stars this second one bought cos readings stable on this IC / but no option to select next addess had to lift pin 1 on IC,s and hard wire the four IC to 3v3 ,// emailed my diappointment to waveshare and they say what u want use two for ,HAHA,”
“given it 4 star // illogical board labelling // SDA/SDL shown opposite 36 and 38
causing incorrect plug connection // the label implies its adjasent to the correct pins 2 and 3 ,,hence not work”
“Beware. I did not appreciate that all 4 GND channels were connected to each other, and to RPi GND, so that all negative sides all get connected together and to RPi GND. Not what I was looking for - I needed 4 completely isolated channels. I have not actually used the product for this reason so I have given it a generous 3 stars.”
