led doesn't light up - 2sdaymars - 08-05-2022
I bought it and used it, but it doesn't work.
I put the code on esphome and turned on the switch, but the led doesn't light up.
i use this code
esphome:

do you have connect power with MOSFET output's terminal?
need connect with DC12V, every 8 channel MOSFET output use a common DC power supply input. see "12/24V DC input" in photo.

thanks so much its work
is there no 16-channel Arduino coding?
RE: led doesn't light up - admin - 08-05-2022
there are many arduino IDE demo source code, you can download at here: https://www.kincony.com/forum/forumdisplay.php?fid=25

RE: led doesn't light up - 2sdaymars - 08-05-2022
I am looking for a code to control 16 channel MOSFETs with Arduino mqtt communication~
i couldn't find
RE: led doesn't light up - admin - 08-05-2022
you can modfiy with this demo source code: https://www.kincony.com/forum/showthread.php?tid=1843
this is KC868-A4 wifi work with MQTT, you just need add I2C code for mosfet output with A16.
