1.1. Description
This document describes the TIGER board. The board mounts two MCUs and can
be used in two different ways.
The MCUs are:
1. the ATSAMD21J18A-64 Ultra low-power microcontroller using the 32-bit
ARM® Cortex®-M0+ processor, and
2. the the KW41Z which is an ultra low-power, highly-integrated single-chip
device that enables Bluetooth® low energy (BLE) v4.2 and IEEE®
802.15.4 RF connectivity for portable, extremely low-power embedded
systems.
The board provides the following peripherals or modules:
•Wi-Fi Module
•EEPROM 32k x 8
It is possible to set up the board in two ways:
•Mode 1: using the SAMD21 as primary MCU
•Mode 2: using the KW41 as primary MCU
Therefore the document is divided in two major sections describing the different
modes of operation.

J7 VCC WIFI
This is a bridge jumper to enable Wi-Fi Module. The module is factory-enabled;
to disable it, it is necessary to remove the R24 resistance.
Figure 8 WiFi jumper
J8 Antenna conntector
The Tiger board features a PCB Antenna and an on-board Antenna connector to
use the KW41 as multi standard radio module
The FRDM-KW41Z RF circuit provides an RF interface for users to begin
application development. A minimum matching network to the MCU antenna pin
is provided through C36 and L7. An additional matching component, L7, is
provided to match the printed F-antenna to 50 ohm controlled line. An optional
SMA is located at J8. This is enabled by cutting the 10 pF capacitor C36. The
following figure shows the RF circuit in detail.

WARNING
Li-Po batteries are charged at 4,2V with a current that is usually half of the
nominal capacity (C/2). This board has a specialized chip that has a preset
charging current of 350mAh. This means that the MINIMUM capacity of the
Li-Po battery shall be 700 mAh.
Smaller cells will be damaged by this current and may overheat, develop internal
gasses and explode, setting on fire the surroundings.
We strongly reccomend that you select a Li-Po battery of at least 700mAh
capacity. A bigger cell will take more time to charge, but won't be harmed or
overheated.

This connector is used to connect the KW41 UART with a PC to be used as console or for
programming particular components located on optional shields (e.g. must be used in
conjunction MCS27561-SH-NXP shield to configure the Crypto chip.)
To use FTDI interface the J13 jumper must be in “B” position as shown in 4.1.4 J13 Uart
