Power Jumpers
The relays can be switched 'as is'; where the NO/C/NO or NO/C of either relay is mapped to pin 1,2,3 for the first relay and to pin 4 and 5 for the second relay. Or they can be mapped to the N/L of the AC input on pin 6 and 7. Diagram:...
Power setup / AC-DC and PoE Jumpers
Power can come from several sources; US, PoE, an external source and an AC/DC transformer on the board.
There are 2 power sets - one for the electronics (typically 5V down to 3v3) and one for the relays and other externals (typically 5v, 12v or 24 volt).
For PoE - unless a variable 68k resister (potentiometer) is mounted and R?? is removed - the external voltage is set to 5V by this register. The resistor allows for 5v to around 40v (given the general the max of PoE on our switch).
The AC/DC transformer can be anything between 3v3 and 12volt. For higher voltages - beware that the 3v3 regulator needs to step it down for the electronics.
The jumps give the following options:
Hardware options
The boards allow for various extra `options'
Pushbutton and LED connectors
Normal two-pin XH 2.54 connector for the LED and for each of the push-buttons (inside the footprint). Same type as often used for fans on PCs.
Pushbuttons are 6x6mm standard pushbuttons; switch at least 10mm high. E.g. https://www.hobbyelectronica.nl/product/push-button-6x6x5/
External/separate current coil
The current coils can be on the PCB - but can also be replaced by a 3.5mm jacket and a standard pickup.

This is used on the Ceramic Oven its NodeCeramic.
Pressure sensor
OLED screen
Used are Oled Display Module 12864 SH1106 I2C screens with 30 pins.
Enclosure
The PCB fits a 150x150 enclosure - such as zp150-150-60 series. E.g: https://www.tme.eu/nl/details/zp15015060jph-pc/behuizingen-universeel/kradex/zp150-150-60jph-tm-pc/ (around 10 euro).
Large 15 pin Connector
A large connector or socket can be used; 3.5mm pitch. E.g. https://de.aliexpress.com/item/1005006345862685.html - around one euro.
Extra IO connector
Normal 2.5mm pitch
Solid state relay
Two types of Solid State relays - in line and 'box'
