DollaTek 5 Stuks DRV8833 1.5A 2-kanaals DC-motoraandrijfplaat Ultra Small Volume Motoraandrijving Module Ingangsspanning 3-10V

Ich falle immer wieder auf die fehlende Brücke rein. Wenn es eine Doku gäbe, das wäre hilfreich.

Buon prodotto. Per pilotare due motori dc. Corrispondente alle specifiche indicate. Dimensioni ridotte.Fornito in una bustina singola per ognuno.

Turns out the ULT and EEP pins on this board are often confused, the "Gikfun" webshop/site shows the same incorrect info as the item description, but a webshop/site called "FilaFill" has the proper pinouts (and a handy diagram) which you can google yourself to confirm (i.e. "DRV8833 FilaFill").Instructions for use: (Original text corrected ULT to EEP - which I guess is short for SLEEP):EEP low level is sleep mode (need to disconnect the J2 short solder joint behind the module - it came disconnected for me which is good - but its not marked with any silkscreen text as to what it does)OUT1, 0UT2 is a 1-way H-bridge, and the corresponding control is IN1, IN2.OUT3, 0UT4 is the second H-bridge, and the corresponding control is IN3, IN4.ULT is the protection output and is not used by default. (You can leave this disconnected if you want)VCC is a voltage input of 2.7 to 10V. (3.3V seems fine for both motor power and logic for the tiny motors im using.)GND is ground.

Attention, certains circuits doivent avoir un défaut de connection dans les pistes de la plaque double face, et il faut brancher directement la patte de validation du circuit intégré via une résistance au pôle positif. Ce n'est rien de grave, au lieu de faire le pont de soudure derrière la plaque on utilise la broche 1 de la plaque époxy. Un très bon produit, utile, petit et efficace.

tutto ok.
