I was testing a mini module (CKCS U1E 65w) for USB charging from a DC source to many USB C protocols.
I've noticed with "vooc" charge at 9v 3.3A the inductor's module is at 90°c
A bit high moreover if it has an enclosure as this one:

With this refurbished adhesive heat sink it falls at 60°c
After many tests I've realised that almost all my board is fried because I've miss read lm7805 instead of lm7809. 😱
Dead list:
Attiny85
Relay
Receiver 433mhz
Morality:
Double check output voltages.
The leds are just clip inside the track done in the wood tray.
Color of the led is selected once for all by soldering and bridging some colors together.
Almost done need to put some soft pad under the feet.
And fix the upper shelf tray with some kind of velcro

The wire has been pull inside the pipe. After soldering.
To pull it I've put a metal wire before soldering.
This because the heat could melt the insulation protection of the wire
