MB500
Part of the MB series
Multiregional RAIN RFID module with +30 dBm and 700 tags/s
The MB500 is the mid-range MB module: 32 x 36 x 4 mm, Impinj Ex10 chip, up to +30 dBm, -82 dBm sensitivity and 700 tags/s. Software sets the band within 865 to 928 MHz for any region.
Choose it when
Your device needs more range and speed than the MB300 gives, but not the top end. 32 x 36 x 4 mm, up to +30 dBm, 700 tags/s and -82 dBm sensitivity.
250 tags/s is enough? Choose the MB300. Need +33 dBm and 1,100 tags/s? Choose the MB700.
