ATtiny Programmer Adapter

A programmer adapter for all the ATtiny DIP models with support for a crystal with optional capacitors or a resonator. You can solder on male headers to make this into an Arduino shield so you can program your ATtiny with the Arduino.

(v1.4 Pictured)

Supported ATtiny models:
ATtiny 13/25/45/85
ATtiny 24/44/84
ATtiny 26/46/86/261/461/861
ATtiny 2313/4313
ATtiny 48/88

Specifications
PCB Board: 53.2mm x 50mm

Includes Eagle schematic/board files, schematic, schematic guide and finished product top picture.

v1.4 (11 February 2014) – Download
– Added headers to allow conversion to an Arduino shield
– Added LED on MISO pin
– Spaced out ISP headers from each other a bit more so you can fit IDC socket connectors

v1.3 (2 July 2013) – Download
– Added a main capacitor and optional capacitors near each ATtiny (thanks to Robert J)
– Added ground in-between the two XTAL pins so you can use a resonator (thanks to Robert J)
– Increased VCC and GND lines from 0.254mm to 0.35mm (thanks to Robert J)

v1.2 (29 March 2013) – Download
– Added resistor and LED to board
– Moved male headers so both ISP headers can fit without interfering each other or with the 28 pin IC socket

v1.1 (7 August 2012) – Download
– Updated PCB labels
– Connected AVCC and GND
– Added optional crystal capacitors
(Bug: 6 pin ISP cable won’t fit if you mount the ATtiny48/88 socket)

v1.0 (16 July 2012) – Download
– Initial Release

Buy the v1.4 PCB only – $4.5

This kit requires you to have your own parts (IC sockets, male/female headers) and will require soldering/assembly.

..

We ship within 2-3 business days and will let you know once shipped. We ship overseas and to reduce shipping costs the kit is sent via the Airmail letter service for $3 and the usual delivery time is 7 – 12 working days (however it sometimes can take 20 working days depending on your location); we ship via Australia Post.
