STMicroelectronics NUCLEO-F303ZE

Overview

NUCLEO-F303ZE from STMicroelectronics is an STM32 Nucleo-144 development board built around the STM32F303ZET6 microcontroller (ARM Cortex-M4F, 72 MHz, 512 KB Flash, 64 KB SRAM, LQFP144). It integrates ST-LINK/V2-1 debugger/programmer, ST Zio expansion connector with ARDUINO® Uno V3 compatibility, and a device-only USB interface via Micro-AB connector - enabling rapid prototyping of motor control, analog signal processing, and sensor fusion applications.

For engineers reviewing the NUCLEO-F303ZE datasheet, NUCLEO-F303ZE pinout, NUCLEO-F303ZE application, or NUCLEO-F303ZE equivalent, this board delivers out-of-box support for STM32CubeIDE, IAR Embedded Workbench®, and Keil MDK-ARM; includes 32.768 kHz crystal oscillator, three user LEDs, two push-buttons (user + reset), and flexible power options (USB VBUS, external supply, or ST-LINK).

Technical Context

The NUCLEO-F303ZE implements the full STM32F303ZET6 feature set including high-resolution timers (217 ps), op-amps, comparators, and 12-bit ADCs with hardware oversampling - optimized for real-time analog-digital hybrid control loops. Its ST Zio expansion header exposes all MCU GPIOs, ADC inputs, DAC outputs, and communication peripherals (SPI/I2C/USART/CAN) in standardized pinout alignment with ARDUINO® Uno V3.

On-board ST-LINK/V2-1 provides debug, programming, and virtual COM port functionality over a single USB Micro-B connection, eliminating need for external probes. Power architecture supports direct VBUS sourcing or external 7–12 V DC input, with onboard regulation to 3.3 V for MCU and peripherals.

FAQ

Does NUCLEO-F303ZE support CAN communication?

No. The STM32F303ZET6 microcontroller on this board does not include a CAN controller peripheral. Unlike NUCLEO-U3C5ZI-Q or NUCLEO-F429ZI, the NUCLEO-F303ZE lacks CAN FD or classical CAN hardware - its communication interfaces are limited to USART, SPI, I2C, USB Device, and SWD.

Can NUCLEO-F303ZE be powered solely via the ST-LINK USB port?

Yes. The board draws power directly from the ST-LINK/V2-1 USB Micro-B connection (VBUS), which supplies regulated 3.3 V to the STM32F303ZET6 and peripherals. No external power source is required for basic operation, programming, or debugging.

Is the ST Zio connector electrically identical to ARDUINO® Uno V3?

Yes. The ST Zio expansion connector maintains pin-for-pin electrical compatibility with ARDUINO® Uno V3, including 5 V-tolerant digital I/Os, analog inputs (A0–A5), PWM pins (3, 5, 6, 9, 10, 11), and UART/SPI/I2C signals - enabling direct use of standard ARDUINO® shields without level-shifting.

What software tools are officially supported for NUCLEO-F303ZE?

ST officially supports STM32CubeIDE (free, cross-platform), IAR Embedded Workbench® (Windows only), and Keil MDK-ARM (Windows only). All integrate with the on-board ST-LINK/V2-1 and provide full debugging, flash programming, and peripheral configuration via STM32CubeMX.
