SAMDK-700
SAMDK-700
Part of the SAMDK series
Raspberry Pi carrier board with Impinj E710, 1,100 tags/s
The SAMDK-700 is the fastest SAMDK: Impinj E710 chip, -86 dBm sensitivity and up to 1,100 tags/s at +30 dBm. A Raspberry Pi and the reader share one 9 to 28 V supply.
You are building a Raspberry Pi reader where speed matters most, with many tags passing fast. Impinj E710 chip, up to 1,100 tags/s and -86 dBm sensitivity, at +30 dBm.
Lower volume? The SAMDK-300 or 500 covers it. Need a ready-to-install fixed reader, not a development board? Choose an EZ model.

Questions we hear
What is a SAMDK for?
It carries a Raspberry Pi and a RAIN RFID reader on one board, so you can build and test an app before designing your own hardware.
How do I connect antennas and power?
Four antenna ports take the antennas. One 9 to 28 V supply powers board and Pi. Output is adjustable from 0 to +30 dBm.
