State

Pretty much operational. Not yet showing things like lights left on.

Bevat [test versie van de software].

Hardware

This is a PoE wired node; to patch port B3 -- see NetworkSetup2018#Patch_Paneel port 22. The board is [Olimex ESP-32 PoE] based.

i2c rfid reader

MFRC522, 3v3

Enclosure on [thinkiverse]. The extra slice is a drilling template.

i2c OLED screen

SD 1306, 128x64, blue, 3v3

Enclosure on [thinkiverse].
