Arduino-format board for low-power, multiprotocol wireless devices
The Tiger board provides a platform for products like smart door locks, portable healthcare technology, wearable sports monitors, RF remote controls, wireless computer keyboards and mice, gaming controllers, security access-control systems, smart energy products, and networking equipment. Arduino connectors allow the addition of new features to designs. The Kinetis KW41Z’s integrated security features, including a hardware AES-256 cryptographic accelerator and a True Random Number Generator, help to keep data and assets safe.
The Kinetis KW41Z wireless MCU is powered by an Arm Cortex-M0+ core, as well as a Bluetooth Low Energy (BLE) v4.2 radio and an IEEE 802.15.4 radio. The device can run multiple wireless protocols concurrently. In addition, the board has Wi-Fi and can support a smart end-node application bridging Wi-Fi to Thread or BLE or it can be controlled locally by a smartphone, or remotely as part of a Cloud-connected network. BLE functionality allows for easy commissioning of products to an IEEE 802.15.4 mesh network.
With -95dBm typical BLE sensitivity and -100dBm typical generic FSK (at 250 kbit/s) sensitivity, both radios enjoy a strong RF link budget. The integration of a DC-DC converter capable of operating from 0.9V to 4.2V, assures that the Kinetis KW41Z MCU has low peak current in receive and transmit modes to extend battery life.
