Jumpers

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'

15 pins Mains connector

The main connector is a 15 pin, 3.5mm K2FEDGK connector/terminal block. Approximate price is 1 euro.

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/ or https://www.tme.eu/nl/details/1301.9304/microschakelaars-tact/schurter/ -- around 50cent.

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.

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'
