TWR-K40X256

The TWR-K40X256 Kit is a Freescale evaluation board powered by the Kinetis K40 microcontroller. The Kinetis microcontroller family is a set of 32 bit ARM Cortex M4 chips which feature flexible storage, lower power usage, high performance and optional Floating Point Unit with many useful peripherals. For more information on the Kinetis family see Freescale's Kinetis website. The Tower System is a prototyping platform with interchangeable and reusable modules along with open source design files.

Board Tips

The TWR-K40X256 features a socket that can accept a variety of different Tower Plug-in modules featuring sensors, RF transceivers, and more. The General Purpose TWRPI socket provides access to I2C, SPI, IRQs, GPIOs, timers, analog conversion signals, TWRPI ID signals, reset, and voltage supplies. The pinout for the TWRPI Socket is defined in Table 3 of the TWR-K40X256 User's Manual, but the user manual does not describe how to order a connector.

A Samtec connector, part number: SFC-110-T2-L-D-A is the proper female mating connector for the TWR-K40X256 TWRPI socket.
