User's Manual

 GPIOs allow interaction with the RS500 as both digital inputs and outputs. They may

be used to trigger inventory, generate events based on inventory activity, or provide

general-purpose user-controlled digital I/O.

 WKUP provides a mechanism to wake up the RS500 from the low power Sleep

mode. WKUP is also used to force entry into the Impinj firmware bootstrap. If

unused, this pin should be tied to logic low.

 UC_ADC allows use of an ADC to convert an analog input voltage into a digital

value.

 UC_DAC allows use of a DAC to generate an analog output voltage from a digital

value.

 BOOT0 provides access to the built-in bootloader in case the Impinj firmware is

corrupted. For more details on the built-in bootloader, please contact Impinj support.

No connect:

 SWCLK and SWD connections are reserved for Impinj use only.
