![]() The USB interface is achieved by using an atmega processor and the rest is done in firmware. Not only is it quite compact, but the design is really elegant. Low speed ranges from 32 KHz to 1MHz.This programmer is based on Thomas Fischl's usb asp design and connects to your computer's USB port. Jumper adjustable programming clock speeds for low clock speed microcontrollers.Low cost USB compatible (No legacy RS232 required).Technical support will not be provided for other microcontrollers. We will provide support only for the above mentioned microcontroller. Note: We have tested stk500v2 programmer on ATmega8, ATmega16, ATmega32, ATmega64, ATmega128, ATmega640 and ATmega2560. Note: If mode is HID, insert HID/CDC jumper (J2) and if mode is CDC, remove HID/CDC jumper (J2). Loading bootloader.a90 file (available from Nex-Robotics) via STK500v2, will take approximately 15 minutes on certain microcontrollers like ATmega2560. ![]() Note: Please set the NEX AVR USB ISP STK500V2 programmer to HID mode for use with GUI. The GUI works on Windows 7(32 Bit), Windows Vista(32 Bit) and Windows XP(32 Bit) please set the NEX AVR USB ISP STK500V2 programmer to HID mode for use with GUI. The NEX AVR USB ISP STK500V2 comes with an easy to use GUI for programming the AVR family of microcontrollers. Note: NEX Robotics USB ISP programmer GUI has not been tested on 64-bit operating system. ![]() For 3.3V microcontrollers, please use appropriate voltage regulators. ![]() The programmer can also power the target board from PCs USB port with limited supply current of up to 100mA. The programmer takes power directly from PC’s USB port which eliminates need of external power supply. ![]() Its adjustable clock speed allows programming of microcontrollers with lower clock speeds. For Windows7 it can be used in HID mode with Avrdude command prompt as programming interface. NEX AVR USB ISP STK500V2 is a high speed USB powered STK500V2 compatible In-System USB programmer for AVR family of microcontrollers. ![]()
