Overview

Figure 1. AT32UC3L-EK Expansion Interface Logical View

There are two expansion headers on the AT32UC3L-EK:

• The J8 header (labeled WLESS on the PCB) connects the Atmel RZ600 AT86RF231 radio board to provide wireless communication capabilities to the kit. Signals on J8.1 and J8.2 are configurable with the J44 header. The AT32UC3L064 modules available on J8 are USART1 and SPI0. Depending on the J44 configuration, TWI0 is available too.

• The J14 and J15 headers provide access to the AT32UC3L064's GPIOs, ground, and VCC3. This offers the possibility to check signals and/or to expand the board with additional hardware.
