STMicroelectronics STM3210B-SK/RAIS

Overview

STM3210B-SK/RAIS from STMicroelectronics is a low-cost starter kit for STM32F103B8T6-based ARM® Cortex™-M3 microcontrollers, featuring the REva universal evaluation motherboard with SO-DIMM daughterboard interface, embedded RLink JTAG debugger/programmer, and 3.3V USB-powered operation. It supports USB host programming, 8 user LEDs, 2 push buttons, ADC-connected potentiometer, I²C EEPROM, RS-232, CAN, SPI, and I²C peripherals - enabling rapid firmware development for industrial control prototypes.

For engineers reviewing the STM3210B-SK/RAIS datasheet, STM3210B-SK/RAIS pinout, STM3210B-SK/RAIS application, or STM3210B-SK/RAIS equivalent, this kit delivers verified hardware/software integration for STM32F10xB-series MCU evaluation, including debug code support up to 64 KB, unlimited Flash programming, and interchangeable daughterboard compatibility across STM32, STR9, and STR7 families.

Technical Context

The STM3210B-SK/RAIS implements a modular evaluation architecture centered on the REva motherboard, which hosts a 20-pin JTAG interface and SO-DIMM slot for STM32103B-D/RAIS daughterboard (featuring STM32F103B8T6). It uses embedded RLink for USB-hosted in-circuit debugging and programming without external power.

Hardware features include dual USARTs, CAN transceiver, I²C bus with EEPROM, SPI interfaces, analog input via onboard potentiometer and temperature sensor, and configurable VDD settings (1.8V/3.3V/5V), all coordinated through Raisonance RIDE7 IDE with GNU C toolchain integration and SIMICE simulation.

FAQ

What microcontroller is pre-installed on the STM3210B-SK/RAIS daughterboard?

The STM3210B-SK/RAIS includes the STM32103B-D/RAIS daughterboard, which integrates the STM32F103B8T6 MCU: a 32-bit ARM Cortex-M3 core running at 72 MHz, with 64 KB Flash, 20 KB SRAM, and integrated USB 2.0 device interface, CAN, and multiple timers.

Does the STM3210B-SK/RAIS require an external power supply?

No - the REva motherboard is fully USB-powered via the embedded RLink debugger interface. No external power adapter or bench supply is needed; VDD rails (1.8V/3.3V/5V) are internally regulated and selectable via onboard jumpers for target MCU voltage configuration.

Can the STM3210B-SK/RAIS be used with other STM32 families beyond F103B?

Yes - the SO-DIMM form factor and standardized pinout allow direct substitution with other REva-compatible daughterboards, including STM32107C-D/RAIS (F107 Ethernet/CAN), STR912-D/RAIS (ARM9), and STR750-D/RAIS (ARM7), enabling cross-architecture evaluation using the same REva base board.

What software tools are included with the STM3210B-SK/RAIS?

The kit ships with Raisonance RIDE7 IDE, GNU C compiler, high-level language debugger, project manager, SIMICE simulator, and RFlasher programming utility. No separate license purchase is required for basic debugging and Flash programming of the STM32F103B8T6 target MCU.
