Most of the external header pins on the KL25Z are wired to GPIO ports ("general-purpose I/O"), which can be connected to external electronics to send digital signals to and from the KL25Z CPU. The diagram above shows the layout of the header pins and the GPIO port assignments.

VREFH is connected to P3V3_KL25Z by default. To supply an external AREF, cut the trace SH1 and install a 0ohm resistor or a wire short on R3. = valid signal options.

The Freedom KL25Z is an ultra-low-cost development platform for Kinetis® L Series KL1x (KL14/15) and KL2x (KL24/25) MCUs built on Arm® Cortex®-M0+ processor. Features include easy access to MCU I/O, battery-ready, low-power operation, a standards-based form factor with expansion board options and a built-in debug interface for flash ...

Order a FRDM-KL25Z - Only $12.95! The FRDM-KL25Z has been designed by Freescale in collaboration with mbed for prototyping all sorts of devices, especially those requiring the size and price point offered by Cortex-M0+ and the power of USB Host and Device.

Spreadsheet of pin connections for all MCU pins. Includes pinout for the I/O headers, Arduino R3 compatibility chart, and OpenSDA MCU pinout. The Freescale Freedom development platform is a set of software and hardware tools for evaluation and development. It is ideal for rapid prototyping of microcontroller-based applications. The.

If you're using the expansion boards, the pins should be configured automatically. If you're using the standalone KL25Z, set the "Wiper" field to the GPIO pin that you connected to the "variable" terminal on the potentiometer.

Sep 30, 2020 · In that tool you can easily identify the pins which have PWM capabilities with the FTM (Flex Timer Modul) hardware, see attached screenshot. Using the pins tool you can see as well which pins have pull resistors (not all have them, and it depends on the device too).

When connecting a TOY to the KL25Z board, use the signal Pin#1 of the channel. There are 4 channels, this means you can connect 4 things per MOSFET board. It can be used to control 100V/33A DC circuit.

FRDM-KL25Z can be used to evaluate the KL1 and KL2 Kinetis L series devices. It features a KL25Z128VLK, a KL2 family device boasting a max operating frequency of 48MHz, 128KB of flash, a full- speed USB controller, and loads of analog and digital peripherals.

The paper provides detailed pinout information for the FRDM-KL25Z development board, highlighting configurations and compatibility with other platforms like Arduino Uno R3.
