Fa'amatalaga o oloa

Ole AS5048 ole 14-bit rotary position sensor ma numera numera (interface) ma le PWM. Ua mamanuina e ams OSRAM Group ma lomia e Arrow.com. E fa'aoga le masini e fua ai le tulaga o se mea taamilo ma maua ai fua fa'atatau sa'o.
O le AS5048 adapter board o se matagaluega e mafai ai ona faigofie suʻega ma iloiloga o le AS5048 sensor e aunoa ma le manaʻomia mo le fausiaina o se suʻega faʻapitoa poʻo le PCB. E mafai ona faʻapipiʻi le laupapa faʻapipiʻi i se microcontroller poʻo le AS5048-Demoboard o se masini fafo.

Fa'amatalaga a le Komiti
O le AS5048 Adapterboard o loʻo faʻaalia ai le ituaiga A (SPI) poʻo le B (I2C), 4 x 2.6mm pu faʻapipiʻi, ma se fesoʻotaʻiga P1. E maua ai se auala faigofie e faʻafesoʻotaʻi ma fegalegaleai ma le AS5048 sensor.

Fa'atonuga Fa'apipi'i

Ina ia faʻapipiʻi le AS5048 adapter board, mulimuli i laasaga nei:

Tu'u se maneta diametric i luga po'o lalo ole AS5048 position sensor.

Ia mautinoa o le maneta e totonugalemu i le ogatotonu o le afifi ma le faapalepale o le 0.5mm.
Taofi le va o le ea i le va o le maneta ma le pusa encoder i le va o le 0.5mm i le 2mm.
