SAMDK reader series - embedded high performance RAIN RFID reader solution for Raspberry Pi
With full flexibility in mind, Identix developed SAMDK which is complete RAIN RFID solution based on Raspberry Pi.
​
SAMDK can be used in a variety of forms:
-
as a development kit "carrier board" for the SAM line of RFID modules
-
as a full-featured reader along with RPi as the main host or
-
as a standalone reader PCB for embedded applications
​
SAMDK implements a dedicated power supply which feeds simultaneously the RFID module and the RPi host. It also integrates a buzzer, an RGB LED, one high-power GPO and one GPI. The communication between SAM module and RPi host can be done via I2C, UART or high-speed SPI interfaces.
​
When using SAMDK (along with RPi) as a standalone reader solution, the ESP-32-S3 MCU present in the SAM module can be disabled or used as an additional co-processor for specific functions. In this scenario the Impinj RFID reader IC is be fully controlled by the RPi host via high-speed SPI interface.
​
Additionally, sophisticated embedded "in-reader" applications can be easily developed to run on the RPi computer using numerous development and integration tools available in the market.
SAMDK AT A GLANCE​
​
SAMDK is available in three different versions, depending on your needs:
​
Reading performance and RX sensitivity
SAMDK-700 +1000 tags/s with -86dBm (max) sensitivity
or
SAMDK-500 +700 tags/s with -82dBm (max) sensitivity
or
SAMDK-300 +700 tags/s with -75dBm (max) sensitivity
​
Except for the RFID reading performance and reading sensitivity, all remaining features and resources are equal among all models.​
