Any Info on the New Digispark Pro?
« on: March 14, 2014, 10:11:22 am »
Hi,
I am very curious about your yet to be released kickstarter product, the Digispark Pro.  It looks to be similar to the Arduino Mini Pro, except it has USB!  Anything you are willing to share about it?

It is attiny based
Has UART, SPI, I2C, EEPROM, PWM on up 6 pins (3 channels), ADC on 10 pins. Same usb capabilities of the Digispark plus Serial over USB support. 16k of flash

It will have full IDE integration including debugging

It will be compatible with Digispark shields as well as new Pro shields which will include WiFi, Bluetooth, and mesh

Launching March 24th or 25th on Kickstarter (as long as Kickstarter approves it)

How do you achieve this? 
Are you going to use the LIN for USB or is that some kind of software-serial using other pins?
I still see PB3 and PB6 as the best USB pins, as portB has already limited pins (XTAL, RST), while on portA all 8 pins could be used for some parallel 8-bit stuff.

Hmmm, lets do some guessing before the official announcement.

So it is an ATtiny, with 16KB of flash.  According to amtel.com, there are 2 ATtiny's with 16KB of flash, the ATtiny167 and the ATtiny1634 (assuming digistump is using announced parts).

Ok, ATtiny167 specs are:
  • 16K bytes of flash
  • 512 bytes of SRAM;
  • 512 bytes of EEPROM
  • 16 Mhz max frequency
  • 20 pins, 16 I/O pins
  • 2 SPI channels
  • 1 I2C channel
  • 1 UART (serial)
  • 11 analog input channels, 10 bits
  • 8 touch channels
  • 2 timers
  • 9 PWM channels
  • 32kHz RTC
  • 1.8 to 5.5 voltage

And the ATtiny1634 specs are:
  • 16K bytes of flash
  • 1,024 bytes of SRAM;
  • 256 bytes of EEPROM
  • 20 pins, 18 I/O pins
  • 12 Mhz max frequency
  • No SPI channels
  • 1 I2C channel
  • 2 UARTs (serial)
  • 12 analog input channels, 10 bits
  • 11 touch channels
  • 2 timers
  • 4 PWM channels
  • 32kHz RTC
  • 1.8 to 5.5 voltage

Due to it having hardware SPI and 16Mhz, I suspect the Digispark Pro will be based on the ATtiny167.

Those are the USB pins we are using.

CDC-Serial will be over those same pins, it will require a driver for windows (none otherwise) but that driver will be provided as a fully signed driver, it will also work with Android devices that allow a CDC device - we will provide an example app for that too.

That sounds, that this device is maxing out VUSB!
Serial over USB, while LIN-UART allows serial connection of WiFi, GPS and other modules.

Any news about kickstarters approval ?

Now targeting the 31st/1st - sorry for the delay, wanted to put some finishing touches on a few features and confirm some prices first. Also been finishing up some work as a technical advisor on this project: https://www.kickstarter.com/projects/glowdeck/glowdeck-a-companion-for-your-smartphone

Thinking it further: Will the solution with "Serial over USB" also be available to the digispark, or does it need some features from the attiny167, the attiny85 does not have?

Due to some unplanned dental surgery it didn't launch yesterday - but it is all ready to go and approved.

I will launch it in the next few days to week depending on when I'm feeling recovered enough for a big influx of orders - a Kickstarter launch usually brings in a bunch of regular orders so I want to be up for that.

Of course a newsletter will go out right after launch, and they'll be chances to pick up extra goodies, etc

That's not anyone's favourite kind.  All the best.

Thank you both for the well wishes! It hasn't been the fastest recovery so far but I'm aiming for launching Tuesday!

Surprised you didn't post an announcement here about the launch! I'm backer #8! In for 3 Pros and some wifi and BTLE shields. :)
