Description

USBasp - USB ISP/TPI programmer stick for Atmel AVR microcontrollers with 5V and 3.3V target voltage based on the design by Thomas Fischl. More information can be found at https://www.fischl.de/usbasp/. Windows users may need to install a driver. Of course this is not necessary for linux and mac users.

Jumper Function
TGTVCC Close to power target device via ISP header
SELFPRG Close to upload firmware to USBasp itself via ISP header
SLOWCLK Close to upload firmware to target device with slow speed (necessary for factory-new microcontrollers)
