Arduino Compatible ASME TIGER Board Supports Thread on NXP Kinetis KW41Z WiSoC

The new Arrow ASME Tiger board is the latest addition to the ASME line up, with an eye towards IoT hardware prototyping. The board carries two MCUs for different types of development depending on the operators need. The board is Thread and WiFi ready, and the Tiger is also Arduino compatible.

The MCU’s are as follows:

      • The ATSAMD21J18A-64 Ultra-low-power microcontroller using the 32-bit ARM Cortex-M0+ processor.
      • The WiSoC is 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 working unit is for very low power applications. The integrated balun reduces system cost and board area, and the sensors are plentiful and easy to access. You’ll find a user guide (PDF), as well a bootloader and sample code on Github.

Specifications for the KW41Z WiSoC

The KW41Z is the NXP ARM Cortex–M0+ microcontroller, ultra-low-power single-chip device that enables Bluetooth low energy (BLE) v4.2 and IEEE 802.15.4 RF for easy portability and extremely low power embedded systems.

The KW41Z integrates a 2.4 GHz transceiver that fully supports FSK/GFSK as well as OQPSK modulations, with an ARM Cortex-M0+ CPU, an up to 512 KB Flash 128 KB SRAM, 802.15.4 packet processor. The peripherals and hardware security are optimized to meet the requirements of IoT prototype applications, as well as other applications.

Block Diagram

The board is sturdy and can mount easily, the layout is appropriate for prototype development, with the ports and I/Os placed at the outside edges for easy access. There are many uses for ASME Tiger, and there can be a great deal of expansion on this addition to the IoT industry. If you want more information, it can be found on the product page on Midatronics website, as well as on Arrow buy page if you intend to purchase the board.

If i’m not mistaken the wireless module in the photos above is the ATWINC1500 wifi module from atmel/microchip, rather than the BLE only KW41Z from NXP?

Jean-Luc Aufranc (CNXSoft)

There are both NXP KW41Z WiSoC and Microchip ATWINC1500 module on the board.
