FYI;-

The heart of Yún is CPU - AR9331, here is the market position of it.

AR9331 (MIPS 24k@400MHz, 1x1:1, 150Mbs/2.4GHz, PHY/100Mbs)

AR9341 (MIPS 74Kc@500Mhz, 2x2:2, 300Mbs/2.4GHz, PHY/100Mbs)

AR9344 (MIPS 74Kc@600MHz, 2x2:2, 300Mbs/2.4GHz, 450Mbs/5GHz, PHY/1Gbs)

QCA9558 (MIPS 74Kc@720MHz, 3x3, 450Mbs/2.4GHz, 1300Mbs/5GHz, PHY/1Gbs)

It is already on bottom of the food chain.

Arduino Tian:

AR9342:MIPS 74Kc@560MHz, 2.4GHz, 5GHz

https://www.arduino.cc/en/Main/ArduinoBoardYun

Difference I see:
  • Built in BLE (Bluetooth)!!!
  • 14 Digital input (20 on Yun)
  • 6 Analog input (12 on Yun)
  • 7mA (40mA on Yun, I think) DC current per I/O pin

Wow, BLE and lower power. Hmmm, but I need more analog I/O!?!

Anyone else?

The main difference for me is Tian replaces ATmega32U4 (Yun's micro) by SAMD21 (Zero's micro).

And AR9342:MIPS 74Kc@560MHz, 2.4GHz, 5GHz (dual band) v.s. AR9331 MIPS 24Kc@400MHz, 2.4GHz

MIPS32 24 Kc  delivers a performance of 1.6 DMIPS/MHz and 3.1 Coremarks/MHz.
MIPS32 74 Kc  delivers a performance of 1.93 DMIPS/MHz and 3.48 Coremarks/MHz

AR9342:MIPS 74Kc@560MHz run 2 times  faster than AR9331 MIPS 24Kc@400MHz.

Apple to apple comparison:


Yun:

Analog Input Channels:12, 10 bit ADC channels
Analog Output Pins:0

Tian:

Analog Input Pins:6, 12-bit ADC channels
Analog Output Pins:1, 10-bit DAC

Tian is far better than Yun if you need analog I/O.

Wow, a beautiful board. I wonder if they will improve the bridge library. And I didnt see a microsd socket.

USB OTG port:

Quote
USB On-The-Go, often abbreviated to USB OTG or just OTG, is a specification first used in late 2001 that allows USB devices such as digital audio players or mobile phones to act as a host, allowing other USB devices such as USB flash drives, digital cameras, mice or keyboards to be attached to them. Use of USB On-The-Go allows those devices to switch back and forth between the roles of host and client devices. For instance, a mobile phone may read from removable media as the host device, but present itself as a USB Mass Storage Device when connected to a host computer.

In other words, USB On-The-Go introduces the concept of a device performing both master and slave roles - whenever two USB devices are connected and one of them is a USB On-The-Go device, they establish a communication link. The device controlling the link is called the master or host, while the other is called the slave or peripheral.

Tian is far better than Yun if you need analog I/O.
Better if you need the extra two bits of resolution, but not better if 10 bits is good enough and you need more channels.

eMMC Flash 4 GB.
Not the same as an SD card: it's smaller, and not removable. That means you can't swap out the card to log more data, copy the files to another computer, or prevent wearing out frequently updated files.

Increased raw power is enticing: but not every application needs maximum processing power, and with the increased power comes some trade-offs that might eliminate it from some some applications.

Far better here is Tian:1, 10-bit DAC v.s. Yun: None

It is true.

On other side micro SD slot has reliability problem, we saw so many threads here already.

Thats what I meant with the microSd. But theres the usb host for flash drives.

Again, better only if you need it. If you don't need it, the feature is meaningless.
