There are three expansion headers on the Atmel AT32UC3C-EK:
• The J25 header (labeled WLESS) to connect the wireless extension board to
provide wireless communication capabilities to the kit. Signals on J25.1 and J25.2
are configurable with the J44 header. The Atmel AT32UC3C0512C modules
available on J25 are USART1 and SPI1; depending on the J44 configuration,
TWIMS0 is available too.
• The J19 and J20 headers provide access to several GPIOs of the
AT32UC3C0512C and ground and VCC3.
• The Atmel AVRMC300 expansion offers the possibility to connect an AVRMC300
expansion motor control board:
o The J33 header provides access to the power driver control signals
(PWM signals).
o The J38 header provides access to the current and back-EMF
measurement (ADC and AC signals).
o The J41 header provides access to Hall-Effect sensors (GPIO
signals).
o The J43 header provides access to quadrature decoder sensors
(QDEC signals).
