Hoi,

Heeft iemand ervaring met de 8 relais module, qua aansturing hardware/software ?

Acht niet, ik heb wel units met twee en vier relais gebruikt. Werkte eigenlijk meteen gewoon goed, kwestie van aansluiten op de wiredout, en dan vanuit de software met on/off schakelen.

Ik gebruik precies zo'n bord. Werkt goed.

Oke dank je wel voor jullie reacties, kun je dan alle 8 relais gebruiken via de nodo ? Of gaat dat via een los slave bordje die alleen maar de relais kan aansturen op de digitale poorten.

Mvg

Ik heb er zo'n I2C naar 16 digitaal-uit chip tussen gezet. Kan ze alle 8 gebruiken vanuit een mega. Vier draadjes: Gnd, SDA, SCL en Vcc. Werkt goed. Relais bordje heeft wel 5 volt nodig, op 3.3 draait het niet goed.

Sluit je aan met 4 draadjes op de Nodo, +5, Gnd en de SCL en SDA van de I2C. De laatste twee worden gebruikt voor je RTC, maar die kan je gewoon doorlussen (tot een meter of zo; langer kan ook met een extender, zie elders op dit forum).

Dus helemaal geen extra poorten nodig op de Nodo.

Op de chip zitten dan 16 digitale input/output pinnen. Met wat commandotjes via de I2C bus kan je die uitlezen, zetten enzovoort.

De chip heeft ook nog 3 adres instel pennen. Dus je kan er in totaal 8 aan je Nodo I2C bus hangen voor in totaal 128 digitale i/o pennen.

Het geval komt o.a. als een 28 pens DIL (als ik goef geteld heb) en kost een paar euro.

Er is geloof ik ook nog iets vergelijkbaars met 8 I/O pennen. Klein prijsverschil maar minder pennen.

Van mijn kant is er behoefte.

Mijn mega output ports zijn vol. Alle 8 aangesloten op het relais boord.
Ik zou graag nog een paar ports voor andere dingen gebruiken.
