MB series
Multiregional RAIN RFID modules, 32 × 36 × 4 mm

Impinj Ex10 modules with four MMCX antenna ports, Wi-Fi and BLE. The band is set by software within 865 to 928 MHz, so one design serves many regions. Three models share the footprint and differ in power, sensitivity and speed.
Choose your model
You make equipment and want to add RFID to your own device, such as a handheld, a smart shelf or a refrigerator. A 32 x 36 x 4 mm module, +27 dBm, 250 tags/s.
Details →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.
Details →You build long-range readers that must read many tags fast and ship to any region. Top of the MB line: up to +33 dBm, 1,100 tags/s and -86 dBm, in 32 x 36 x 4 mm.

Questions we hear
Does it work in any country?
Software sets the band within 865 to 928 MHz, so one hardware version serves many regions. It is FCC and Anatel certified.
What do I need to run it?
A 5 V supply and antennas on its four MMCX ports. It has its own dual-core MCU, or you can drive it from a host. Identix does not supply tags.
