SAMDK series
Embedded 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:
1. as a development kit "carrier board" for the SAM line of RFID modules
2. as a full-featured reader along with RPi as the main host or
3. 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 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 A T A GLANCE
SAMDK is available in three different versions, depending on your needs:
SAMDK-700 +1100 tags/s with -89dBm (max) sensitivity
SAMDK-500 +700 tags/s with -81dBm (max) sensitivity
SAMDK-300 +300 tags/s with -73dBm (max) sensitivity
Except for the RFID reading performance and reading sensitivity, all remaining features and resources are equal among all models.
