This project is about to build a small and tiny (48mm x 19mm) development board based on a Freescale Kinetis K20 device (ARM Cortex-M4 running at 50 MHz). The microcontroller pins are on the outside to use the board with a breadboard. The board includes the option for an micro SD card, 32 kHz clock and a 3.3V DC-DC converter. The ARM Cortex can be debugged with standard development tools (Eclipse, GNU, SWD).
Main Features
- Freescale Kinetis K20DX128 Microcontroller (K20DX128VFT5)
- ARM Cortex-M4, 50 MHz, 128 KByte FLASH, 16 kByte RAM
- USB, ADC, DMA, FTM, I2S, I2C, PIT, GPIO, UART, TSIO, CMP, DAC
- Internal 5V to 3.3V DC converter (120 mA)
- Optional Micro SD card
- Optional 32 kHz RTC clock
- Optional 3.3V DC-DC converter
- Compatible to OpenSDA circuit on Freescale FRDM boards
- Microcontroller pins breadboard friendly on the outside
- Standard ARM SWD (Single Wire Debug) for flashing and debugging
- Detachable debugging circuit: board can debug external boards
Applications
- Data logger
- Wearables
- Robotics
- Debugger (OpenSDA, OpenOCD, pyOCD, CMSIS-DAP)
Example projects available for Eclipse (GNU ARM Eclipse with GNU lauchpad)/Kinetis design Studio.
