Takiuino V2 - pro-style 644/1284p board, 18 pins per edge

Based off the (working) Takiuino v1, the v2 is a more generic layout which exposes all of the pins available of the 644/1284p chips. Sadly couldn’t keep the board the same width as the other boards in the range (nano, pro mini, pro micro, teensy, etc), this is one 2.54mm pin width wider.

Code soon available (based on the mighty 1284 code)

Simple Teensy 3.1 add-on board to test the relative performance of various state-of-the-art MEMS pressure sensors. Included is Invensense’s 3.5 mm x 3.5 mm ICM20730 7-axis motion sensor with accel/gyro and embedded pressure sensor, Bosch’s 2.5 mm x 2 mm BMP280, ST Microelectronics' 2.5 mm x 2.5 mm LPS25H, and Measurement Specialties' 3 mm x 3 mm MS5637. Broken out are all interrupts (ICM20730 and LPS25H) and all I2C device address bits (ICM20730, BMP280, and LPS25H) to avoid address conflicts. Also broken out is the ICM20730 FSYNC pin to test electronic image stabilization.
