2.4 Main board description
Here’s the overview of all functions on the main board.
Here’s the overview of how EVB looks like:
Figure, Top overview
As you can see in the picture, here’s the major component you must know before you start your design:
⚫KL520: AI SoC.
⚫5V Power (J16): 5V input for the development board, used a 5V/2A adaptor.
⚫Micro USB connector: Supply 5V input, also used the USB interface for developing.
⚫UART0/UART4: a connector that uses a TTL to USB cable for developing.
⚫PTN: a button that used to turn on the KL520.
⚫Micro USB connector: Supply 5V input also used it for developing.

2.5 Pin mux and Jumpers
To make some flexibility for the developers, the development board has made some jumper options. Most
IOs has series jumper on it. If users want to do some other thing that do not include in development
board, he can just take off the jumper and jump to other peripherals or even scope for debugging. Some
IOs also offers different functionality, users can simply choose different functions by choosing different
jumper location. Bellowing table shows the hardware setting on the development board.
Table, Development board HW setting
Boot strap setting ( J17 )
◆Pin 1-2 : Boot_IPL_SEL, default short
◆Pin 3-4 : Boot_SPL_SEL
⚫Short: SPL is specified by UART
⚫Open: SPL is located in SPI flash

3. Peripherals
Here list the peripherals you need for the board development.
3.1 5V adaptor
A 5V/2A micro USB is needed to provide the power of evaluation board. The package only have USB-A male
to micro USB cable but not power adaptor
