Customer Comments

  • Will you be carrying a 20 pin DIP socket soon?

  • i’m longtime arduino user but i never breadboarded the attiny chips, this would be my first… i assume this should work fine but i’ll ask a newb question…

    can i use the adafruit cc3000 wifi breakout module the same way that i would on a full arduino? is this mostly true for all arduino compatible components?


  • Does this have an Eagle part?

  • the product card link no longer works.

  • Any plans to sell the ATtiny261? Am In incorrect that the 261 is basically the “newer” version of the 2313, giving up the built-in serial for more ADC channels?

  • Can anybody tell me the avrdude CMD line to write the fuse bits to put a 16 M Hz crystal on this MCU? This calculator only has up to 8 M Hz crystal

    Something like this: avrdude -p usbtiny -c t2313 -U lfuse:w:0xce:m -U hfuse:w:0xdf:m -U efuse:w:0xff:m

    I did this and now the MCU is locked up.

  • can we put an arduino bootloader in it?? like the uno bootloader???

    • Sort of. Not the bootloader, but you can program it with Arduino. Here’s a link. It’s fairly easy! There’s also stuff for ATTiny85’s on that site.

  • would this work with the msp-exp430 lunch pad?

  • Could you load the Arduino bootloader on this?

    • Yes…but it’s much better to get yourself a $15 ISP programmer to use with these bare chips. Something like this:

      In the Arduino IDE the only difference you’ll notice is you select an option from the “Tools->Programmer” menu instead of a COM port. You get more features than COM though, eg. You can set ‘fuse’ settings on the chips (to select clock sources, etc. (which you’ll need to do with this chip unless you want it locked at 1mHz)

      You also don’t lose a couple of K of flash memory to the bootloader - very important when you only have 2K of program space!

      • Okay. Thanks.<br />
        You can put it on ATTiny’s: <br />

    • I don’t believe you can… that would be the atmega168 and atmega328.
