The Freedom-K64F is an ultra-low-cost development platform for Kinetis K64, K63, and K24 MCUs. Form-factor compatible with the Arduino R3 pin layout Peripherals enable rapid prototyping, including a 6-axis digital accelerometer and magnetometer to create full eCompass capabilities, a tri-colored LED and 2 user push-buttons for direct interaction, a microSD card slot, and connectivity using onboard Ethernet port and headers for use with Bluetooth and 2.4 GHz radio add-on modules OpenSDAv2, the NXP open source hardware embedded serial and debug adapter running an open source bootloader, offers options for serial communication, flash programming, and run-control debugging.
