Schematic

Power supply

Microswitches

ADuCino360 board is equipped with two microswitches:

• S1 – reset button
• S2 – connected to GPIO P2.2 line. It can be used in user applications, it can also activate bootloader

3D accelometer

ADuCino360 board is equipped with ADXL362 3D digital accelerometer (U4) with SPI interface. It is connected to ADuCM360 SPI0 interface. SPI0 lines are also available on Con1 connector (KAmod standard).

Temperature sensor

ADuCino360 board is equipped with ADT7420 digital temperature sensor with I2C interface. Sensor is connected to ADuCM360 I2C interface, its lines have pull-up resistors (R2, R3). Sensor I2C address is 0x48.

USB<->UART converter

ADuCino360 board is equipped with bidirectional USB<->UART converter (U5). It can be used in user applications to communicate with PC. It is also used by bootloader for Flash programming. To connect USB<->UART converter to P0.1 and P0.2 microcontroller pins put JP1 and JP2 jumpers in „On” position

ADuCino360 board’s microcontroller has built-in bootloader (On-Chip Kernel), it lets Flash memory to be programmed with data received from UART interface. To activate bootloader press S1 button (reset) while holding S2 button. CM3WSD software is needed to perform flash programming, it is available at Analog Devices website.

Interface SWD

ADuCM360 microcontrollers have SWD interface (Single Wire Debugging), designed for debugging and flash programming. ADuCino360 Con3 connector has standard SWD/JTAG pinout, therefore it is compatible with most popular debuggers: uLINK, J-Link etc.

GPIO and ADCin connectors

ADuCM360 microcontroller digital GPIO lines and analog inputs are available on 2.54mm gold-pin connector, its pinout is shown on picture below.

SPI connector

ADuCM360 SPI0 interface is available on Con1 connector (KAmod standard). Note that SPI0 lines are also connected to built-in accelerometer.

I2C connector

ADuCM360 I2C interface is available on Con2 connector (KAmod standard). Note that these lines are also connected to built-in temperature sensor.
