 Below, I cover a few cases to get you started. Most of these use the USBtinyISP.((As near as I can tell, the original source of the USBtinyISP design is Dick Streefland's [[https://dicks.home.xs4all.nl/avr/usbtiny/|USBtiny]]. Additional development and refinement leading to the [[https://learn.adafruit.com/usbtinyisp|USBtinyISP]] was done by Limor Fried. The software and hardware are open source (GPL and CC BY-SA 2.5), leading to many clones and derivatives.)) Owing to its low cost and wide availability, this is one of the most popular options. The [[https://learn.adafruit.com/usbtinyisp|original USBtinyISP]] is available sporadically through Adafruit, and clones derived from the open source design similar to [[https://www.ebay.com/itm/USBTiny-USBtinyISP-AVR-ISP-programmer-for-Arduino-bootloader-Meag2560-uno-r3/382580265905|this one]] are widely available at auction sites, Amazon, Banggood, etc. All my testing was done using USBtinyISP clones from two different suppliers.
-The original USBtinyISP has a built-in 3x2 keyed IDC cable that carries the signals needed for ISP (in-system programming). It also has a 5x2 keyed IDC cable that carries the same signals but in a different layout.

-If you are using a USBtinyISP clone, there's a good chance it has a 3x2 ISP header in addition to a 5x2 ISP header. The following assumes this is the case and also that you have a 3x2 keyed IDC cable. Such a cable is often included with USBtinyISP clone purchases. Finally, I'm assuming it works at 5VDC, which is the defacto standard.

 Depending on the board you are programming, you may need to use Dupont wires (M to F or F to F depending on your USBtinyISP) instead of the IDC cable.
