STMicro already announced a $24 NFC development kit a few days ago, and they’ve now announced new ultra low cost STM32 development boards. STMicro Nucleo development boards are based on different STM32 MCU based on ARM Cortex M0, M3 and M4, feature Arduino headers, and are supported by mbed platform.
There are currently four boards available:
- NUCLEO-F401RE – Based on STM32F401RET6 ARM Cortex M4 MCU @ 84 MHz with 512KB flash memory, 96 KB SRAM
- NUCLEO-F030R8 – Based on STM32F030R8T6 ARM Cortex M0 MCU @ 48 MHz with 64KB flash memory, 8KB SRAM
- NUCLEO-F103RB – Based on STM32F103RBT6 ARM Cortex M3 MCU @ with 128KB flash memory, 20 KB SRAM
- NUCLEO-L152RE – Based on STM32L152RET6 ARM Cortex M3 MCU @ 32MHz with 512KB flash memory, 32KB SRAM
All four boards share the following specifications:
- STM32 microcontroller with LQFP64 package
- Two types of extension resources
- Arduino Uno Revision 3 connectivity
- STMicroelectronics Morpho extension pin headers for full access to all STM32 I/Os
- mbed-enabled (mbed.org)
- On-board ST-LINK/V2-1 debugger/programmer with SWD connector – selection-mode switch to use the kit as a standalone ST-LINK/V2-1
- Flexible board power supply
- USB VBUS or external source(3.3 V, 5 V, 7 – 12 V)
- Power management access point
- Three LEDs – USB communication (LD1), user LED (LD2), power LED (LD3)
- Two push buttons – USER and RESET
- USB re-enumeration capability: three different interfaces supported on USB: Virtual COM port, mass storage, and debug port
As you can see from the diagram below, they should eventually be at least 8 Nucleo boards to choose from, based on STM32L0, STM32F0 and STM32F3 MCUs. The company will provide a software HAL library including a variety of software examples, and beside the mbed platform, the boards will be supported by other Integrated Development Environments (IDEs) such as IAR, Keil, GCC-based IDEs.
All for boards are currently available for $10.32 via STMicro Nucleo page, where you’ll also find user’s manuals, schematics, gerber files, and links to development tools, firmware and drivers. Four more boards, namely Nucleo-F072RB, Nucleo-F302R8, Nucleo-F334R8, and Nucleo-L053R8 boards will be introduced in Q2 2014. The company will showcase the boards are Embedded World 2014 in Germany on February 25-27, and if you happen to get there you may get a free sample. All you need to do is to register here.
