Connection of Arduino and Linux allows wireless programming and control of the device via IEEE802.11n 2x2 2.4/5 GHz dual-band Wi-Fi network. The module is based on two microcontrollers: Atheros AR9342 MIPS 533MHz and SAMD21G18 , has ARM Cortex-M0+ core, 256 kB of flash memory, 32 kB of RAM, 20 digitalinputs/outputs of which 12 are PWM and 6 analog inputs and interfaces,including USB and Ethernet.
Output distribution is compatible with Arduino Shield overlays.
Arduino Tian uses two microcontrollers:
Tian board can be programmed from Arduino IDE environment and configure or change and read the states of the outputs wirelessly via WiFi. After connecting the power supply (5 V through a power supply with micro USB connector), the module is visible on the PC as a WiFi network called Arduino Tian. The device also has Ethernet 1000 Mbit/s port and Bluetooth 4 .0 module.
The subject of sale is original Arduino product, Botland is an official distributor of this company.
Below we present some features that distinguish Arduino modules from other programmable tiles.
|Thanks to the installed bootloader, the appropriate microUSB cable and software from the manufacturer is sufficient to program the device.|
|Arduino Tian supports WiFI 2 .4GHz dual-band 802.11 b/g/n connection . This allows you to easily, wirelessly, through WiFi network, program, configure or change and read output states.|
|The CSR8510 Bluetooth BLE 4.0 / EDR communication system is on board.|
|This version has an Ethernet controller with a 10/100/1000 Mbit/s RJ45 connector.|
|The layout of connectors enables installation of dedicated Arduino Shield covers.|
|14 digital inputs/outputs enable, among other things, to control LEDs, relays and read button statuses.|
|The maximum current capacity of a single output is 7 mA. The outputs operate with a voltage of 3.3 V.|
|12 PWM outputs allow e.g. for motor control and LED brightness adjustment.|
|6 inputs of the built-in 10-bit analogue-to-digital converter support, among others, sensors with analogue output.|
|The device supports popular communication interfaces, among others: UART, I2C and SPI and USB.|
|Special functions||Some pins have special functions, a brief description of which is available in our guide .|
The socket .
|The board has a built-in USB controller, which is connected to a USB type A computer socket.|
|Memory - two microcontrollers
5 V power supply
|You can use a 5V power supply unit with microUSB connector to power Arduino.|
|You can power the board from your computer viathe microUSB cable, whilekeeping in mind that the maximum current capacity of the USB port is 500 mA. Arduino has a system that protects the socket against short circuit and too high current flow.|
The connector .
|The module has ICSP outputs for connecting an external AVR programmer.|
|The IOREF pin allows for direct access to the voltage with which the I/O outputs work - in this case 3.3 V.|
|The connected LED on pin 13 allows debugging of simple programs.|
|The built-in voltage regulator allows external devices to be supplied with 3.3 V with a current consumption of up to 7 mA.|
