The last note about the Arduino Zero was dated 18th Sept, and on the arduino.cc website there's also nothing new

Does anyone know when it will be released?

Atmel seem to be getting rather good at vapourware.

The Atmel Zero has a design that has a slight chance of appealing to a very small number of users.

Versus the Teensy 3 or LC, or using the $30 Mikroe ST-mini with ST-Link and a real compiler like GCC or IAR. 

Or an Olimex board.

Or a ST Nucleo or ST Discovery.

Kinda looks like NXP is treading water in ARM-land now.

Freescale - opinion - M0, M4: nice work but without comprehensible documentation, they're inferior.

 

Sorry Atmel, with the zero you aimed wrong for the upwardly seekng Arduino crowd, and too confabulated for professionals. But the Zero is just a marketing thingy.

I think awneil was trying to redirect several old zero-related threads to a single place...  Doesn't seem to have worked.

 

I always figured that zero was going to be similar in price to the Uno, but with a more modern processor, and a debugger.  After all, the samd21 is similar in price (at digikey, in small quantities) to an ATmega328, and there are other possible cost reductions with a bit of careful design.   But NO!, the Zero that Arduino.org is priced like a Due, but has fewer pins.  (One of the reasons I suspect that Zero was "straw that broke the camel's back" in the whole arduino vs arduino thing.)  Sigh.

Indeed.

Evidently not.

My Zero Pro arrived on Wednesday.     Surely it was designed by the Arduino team rather than Atmel.

 

Yes,   it is priced far higher than a FRDM or NUCLEO board.    But Arduino SRL presumably need to make a profit.

Freescale or ST produce the FRDM and NUCLEO at cost.    Presumably with a small margin for Digikey, Farnell etc.

 

However,  you have exactly similar hardware.     i.e. target MCU with Arduino headers.   plus a EDBG chip for CMSIS-DAP and COM port via USB.

The traditional UNO or MEGA is not that different.     i.e. target MCU with Arduino headers.   plus a glue chip for COM port via USB.

 

From the chip manufacturer's point of view,   the cost of the EDBG chip or an ATmega16U2 chip is insignificant.

The software development for EDBG or USB->UART has already been done.    AFIK,   ARM provide the CMSIS-DAP source code.    So Freescale, NXP, Atmel just have to build for their chip.

 

If Atmel or the Chinese ever produce "EDBG" chips for mass market,   the manufacturing cost of a UNO vs ZERO PRO will be comparable.

tell me again... why we need the EDBG chip when the ARM MCUs have SWD built-in? Works fine for me with STM32F4xx

The key thing the EDBG provides the interface between SWD and the host's USB.

 

It also does a virtual COM port, plus SPI, I2C and 4 GPIOs (though I don't know if the Zero and/or Zero Pro use them)

 

It is the equivalent of the ST-Link.

Yes, it struggles to compete with the likes of Nuvoton's bundle here (3 boards - Ardunio clone + LED Top + Serial-bridge (not needed for debug) 

https://octopart.com/nutiny-evb-...

This NUC472 has True 5V operation, so is Shield compatible

It also has M4 Core, Ethernet, and USB HS and on-board Debug, and CooCox is one group who will be supporting Debug on this.
