A very small ISP programmer for AVR chips.
Based heavily off of the VUSBTiny-AVR-SPI-Programmer](http://www.instructables.com/id/VUSBTiny-AVR-SPI-Programmer/), with some additional features.
-
Level shifting options for 3.3V, 5V programming
-
Option for high-voltage reset
-
Very small footprint
-
Low cost design
-
Ability to use pogo pins for quick programming, or use headers for prototyping
Wishlist
- Integrate USB-COM support to allow target to pass messages to host via SPI
V2
-
Fix current limiting resistors being on the wrong side of the diode
-
Fix missing pull-up resistors on target side of level-shifting mosfets
-
Add a place to connect 12V for high-voltage reset
-
Improved bottom graphic
-
Improved pad layout for pogo pins
V1
- Initial Design board layout
