3.2 Board features 3.2.1 FRDM-KW41Z board The FRDM-KW41Z development board is based on NXP Freedom development platform. It is the most diverse reference design containing the MKW41Z device and all necessary I/O connections for use as a standalone board, or connected to an application. You can also connect it to the Freedom development platform.
3.3 Serial and Debug Adapter The FRDM-KW41Z development board includes OpenSDA v3.0-a serial and debug adapter circuit that includes an open-source hardware design, an open-source bootloader, and debug interface software. It bridges serial and debug communications between a USB host and an embedded target processor as shown in Figure 3.
