Another all-in-one PCB

[jeti]

Hi all,

as many of you already did your own design, I also started working on that, as any other solution only covered 75% of my whishes .
Therefore i established my own :bowtie: , but as I am a beginner in Hardwaredesign I would like to ask for your opinion to do as little mistakes as possible.

What i wanted:

• arduino Pro mini (china)

• 2 LED Dimmer circuits

• 1Wire for SHt7021 and light sensor

• DS18b20 connection

• PIR connection

• small form factor (no mounting holes needed yet)

thats what i came up with (KiCad files):
0_1459080161874_Mysensor_1.pdf
0_1459080236009_Mysensors_01.kicad_pcb
0_1459080257370_Mysensors_01.sch

It would be great to get some feedback about layout and the schematics!

thanks in advance!
