STMicroelectronics STZB-SK/RAIS

Overview

STZB-SK/RAIS from STMicroelectronics and Raisonance is a low-cost ZigBee® starter kit comprising the SNRCM-260 module, REva motherboard, STM32F103RB and ST7FLITE3 daughter boards, EmberZNet™ 3.0.1+ stack, EZSP SPI interface, and embedded RLink debugger. It enables rapid prototyping of wireless sensor networks and light control systems using ST microcontrollers.

For engineers reviewing the STZB-SK/RAIS datasheet, STZB-SK/RAIS pinout, STZB-SK/RAIS application, or STZB-SK/RAIS equivalent, this kit delivers pre-integrated ZigBee networking, in-circuit debugging via USB, SPI-based MCU-to-radio communication, and ready-to-run sensor/sink and light/switch reference applications - all on a single evaluation platform.

Technical Context

The kit centers on the SNRCM-260 module, a preprogrammed single-chip ZigBee solution based on the Ember EM250 SoC, operating at 2.4 GHz (IEEE 802.15.4), with integrated 2.4 GHz RF transceiver, 8051 core, and 128 KB flash. It interfaces exclusively via Ember's EZSP protocol over SPI at up to 1 Mbps.

REva motherboard provides universal MCU evaluation with SO-DIMM socket, configurable VDD (1.8V/3.3V/5V), I²C EEPROM, analog inputs (potentiometer, temperature sensor), and digital I/O (LEDs, buttons). Embedded RLink supports in-circuit debugging and programming for both STM32 and ST7 targets via USB.

Key Specifications

Availability

Manufacturer

STMicroelectronics is a global semiconductor leader headquartered in Geneva, designing and manufacturing microcontrollers, analog ICs, MEMS, and power devices for industrial, automotive, and consumer applications.

This kit belongs to ST's ZigBee connectivity enablement product line, developed jointly with Raisonance to accelerate wireless integration into ST7 and STM32-based embedded systems using standardized software stacks and hardware abstraction layers.

FAQ

Does STZB-SK/RAIS include the InSight USB Link?

No. The InSight USB Link and EM2USB command-line interface are included only in the SN260-2SK/RAIS dual-kit variant. STZB-SK/RAIS contains one SNRCM-260 module and relies on the SPI bootloader through the STM32F103RB for firmware updates, requiring EmberZNet 3.0.1 or newer stack images.

Can STR7 or STR9 daughter boards be used with this kit?

Yes, but they are not included. The kit documentation confirms software libraries for STR7 and STR9 are provided, yet physical daughter boards must be purchased separately from ST sales offices. Only STM32F103RB and ST7FLITE3 boards ship with STZB-SK/RAIS.

Is Flash debugging supported on the STM32F103RB board?

No. The documentation explicitly states the starter kit does not support Flash debugging. Debugging is limited to RAM-based execution using the embedded RLink interface; breakpoints and variable inspection are functional only when code runs from SRAM.

What ZigBee application examples are provided out-of-box?

Three validated C-based applications are included: (1) Version - retrieves EmberZNet stack version and EUI64 address; (2) Sensor/Sink - implements distributed sensor data collection over ZigBee mesh; (3) Light/Switch - demonstrates remote on/off control of lighting nodes using ZigBee cluster library commands.
