The
Tian is a new board from
Arduino that is driven by an Atmel SAMD21 MCU, that features a 32-bit ARM Cortex M0+ core, and a Qualcomm
Atheros AR9342, a highly integrated MIPS processor that can operate up to 533MHz, and supports a Linux distribution called Linino.
For communication the board has a feature-rich IEEE802.11n 2x2 2.4/5 GHz dual-band Wi-Fi module. 802.3 10/100/1000Mbit/s Ethernet and CSR 8510 Bluetooth with EDR/BLE 4.0 connectivity are also provided. The
Tian has a built-in 4GB eMMC memory that enables feature-rich project construction. It is possible to switch On/Off the Linux port from the MCU to reduce the power consumption.
The CPU operates on 3.3V and has 16MB of Flash memory as well as the 4GB of eMMC and RAM is 64MB of DDR2. The MCU also uses 3.3V and has 256KB of Flash memory, 32KB of SRAM and a clock speed of 48MHz.
Power is provided via the USB connection or from an external 600mA 5V power supply, with automatic selection of power source. The board has 6x analog I/O pins and 20x digital I/O pins that can be used for both input and output.
For communication with computers, other Arduinos or other MCUs as well as phones, tablets, cameras, etc. there is 1x hardware UART and 3x hardware USARTS for 3.3V serial comms. The USB port is connected to the I/O controller, allowing serial (CDC) communication over USB. The MCU also supports TWI and SPI communication and the Arduino software includes a Wire library to simplify the use of the TWI BUS. For SPI communications, the SPI Library is used.
