STEVAL-IDZ301V1 and STEVAL-IDZ302V1 are demonstration boards for the SPZB32W1 series of IEEE 802.15.4 ZigBee® radio communication modules. They feature an integrated RF module, a 20-pin JTAG connector for programming and debugging, hardware support for application development, a temperature sensor, circuitry for measuring battery voltage, two configurable buttons and LEDs, a Mini-USB connector and USB-RS-232 bridge, a reset button for selecting the power source, an LED power indicator, jumpers for boot activation, jumpers for serial communication setup, and a 24-pin double-row header for accessing the remaining STM32W GPIO signals and interfaces. The kit includes a software library with utilities and application samples.
