I think HAL-wise the Kwikstik board is the same as the twr-40x256, it
just exposes different features of the MCU through the attached devices,
which include a microphone, a buzzer, an audio output, rechargeable
battery (with usb charging), a dot-matrix LCD.

The Kwistik is attractive because of its low cost (~$30), and even comes
with an on board Segger J-Link chip! Seems like an affordable base for
all kinds of hobby projects.

I think just having an additional target might work with all the
differences handled in device implementation, and all the HAL
functionality subsumed under the twr-k40x256, e.g., in the case of the LCD.
