All modules from point 13, 14 & 15 can work at the same time without interferences.
Five connectors with four pins with I2C bus and 3.3V power for future extensions.
External extension bus connector to connect future external modules to ATxmega parallel data bus, such as Displays, more motors controllers, image sensors etc.
Possibility to monitor power consumption from main accumulator.
Possibility to monitor generated power by the photovoltaic panels.
Possibility to monitor voltage of the main accumulator.
Possibility to monitor power consumption of each motor powered by on-board driver.
Robots: contain on-board dual asynchronous motor driver and four connectors to control eight servomotors, powered from an Li-Ion accumulator and support to charge the accumulator from two photovoltaic cells or from an external source, several communication modules: Bluetooth Class1, EFM12BP for long distance communication up to 5Km and RFM12BS for low power and short distance communication up to 300m.
Audio player: contain on-board VS1011, VS1033 or VS1053, single or dual micro-SD memory card connectors with push.
Audio/Video(low quality) player.
General development application because has all possibility to connect with another controller or another peripherals to the expansion bus, the expansion connector work to speed of the external ram memory, because the expansion peripherals is mapped to address space 524288 to 1048576, maximum number of expansion peripherals is 65536.
Power supply input between 3.4V and 9.5V
Maximum supported input voltage on photovoltaic connectors and the main accumulator: 9.5V, Maximum absolute 10.5V.
