Core clock up to 192 MHz
512 KB embedded Dual Bank Flash and 160 KB SRAM
Audio codec (NAU88L25) with Microphone In and Headphone Out
Ethernet (IP101GR) for network application
USB 2.0 High-Speed OTG / Host / Device
USB 1.1 Full-Speed OTG / Host / Device
External SPI Flash (Winbond W25Q20) which can be regarded as ROM module
MicroSD Card slot for T-Flash
M487 extended interface 4 connector with 36 pins each
Arduino UNO compatible interface
Three push-buttons: one is for reset and the other two are for user-defined
Four LEDs: one is for power indication and the other three are for user-defined

More information about the board can be found at the PFM M487 User Manual_.

Supported Features

.. zephyr:board-supported-hw::

The on-board 12-MHz crystal allows the device to run at its maximum operating speed of 192MHz.

More details about the supported peripherals are available in M480 TRM_

Building and Flashing

Flashing

Here is an example for the :zephyr:code-sample:hello_world application.

On board debugger Nu-link-Me can emulate UART0 as a virtual COM port over usb, To enable this, set ISW1 DIP switch 1-3 (TXD RXD VOM) to ON. Connect the PFM M487 IoT to your host computer using the USB port, then run a serial host program to connect with your board. For example:

.. code-block:: console

$ minicom -D /dev/ttyACM0

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: numaker_pfm_m487 :goals: flash

Debugging

Here is an example for the :zephyr:code-sample:hello_world application.

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: numaker_pfm_m487 :goals: debug

Step through the application in your debugger.
