Tiny25 and Tiny2313 kits

It took a bit longer than I expected to get the new kits on the blog shop. But hey, I’m a software developer, we never deliver on time ;).

Finally all parts arrived and all pictures are taken. There are two new howtos with detailed step-by-step instructions and schematics, Tiny25 header and Tiny2313 header. And get a kit in the shop if you like.

Sorry, the shop is closed.

  1. Tiny2313 kit parts list: I think you mean 20-pin socket, not 8-pin.

  2. Could you use an ATTiny13 in the Tiny25 header kit?

    Also, have you considered selling just the boards alone, not in kit form?

    Great idea; cool execution. Best o’ luck.

  3. Yes, ATtiny13 is also possible, but it can’t use the resonator (no XTAL pins).
    And yes, the boards alone are also availabe in the shop.

  4. Grats that you finished it!
    These are great help! Well done! Looking forward to your next tinkering!

  5. Only complaint I have is working out which way to plug a ftdi cable onto the 2313 board. The silkscreen just indicates pin 1.

    Compare with the silkscreen on a boarduino which makes it a lot more obvious.

    Other than that they are great. Smaller, neater and easier than building the same thing on stripboard.

  6. Ok, I see. I will look into that for the next batch. Thanks for the feedback.

  7. If you put a jumper from pin 4 (XTAL2) to ground, you can use the socket for most 8pin AVRs with internal clock.

  8. Thanks Alex, super cool PCB, built mine last night and works like a dream. Can you confirm that jumping Pin 4 of the chip socket to ground will allow me to work with a Tiny13?

    Is it possible to program the chip when it is still in-circuit? I though this was the whole point of ISP. I get errors if I try and flash a new hex to the chip if it has load (LED’s on PB0 and PB1) on the pins. If I disconnect the LED’s from Ground, everything works fine.

  9. Hi Jim,
    actually pin 4 is already GND, I think Franks means from pin 3 to pin 4. But no, I haven’t tested that yet.

    For the ISP problem, most of the time the programmer is not able to pull the lines up, that are connected to LEDs or other loads. For example, for the USBtinyISP, that I am using, I had to short two resistors to be able to drive lines that were connected to LEDs.

  10. I got mine today – with a nice blue PCB and a sticker. Now I don’t have to memorize the resistor colors anymore ;-)

    I flashed it with some demo code of my own and (once again) stepped into the FUSE settings trap. I really should memorize that factory settings are 1MHz internal RC oscillator… or RTFM for once.

    The new 4313 is coming btw…
