USBASP USBISP 51 AVR Programmer Downloader with Cable 180°

Description

Product Overview

The USBASP USBISP 51 AVR Programmer Downloader is a professional-grade in-system programmer designed for 51 and AVR series microcontrollers. Based on the open-source USBASP project, this programmer connects to your computer via a standard USB port and uses the ISP (In-System Programming) protocol to flash firmware, erase chips, and configure fuse bits without removing the target microcontroller from its circuit .

Whether you are developing embedded systems, working on Arduino projects (burning bootloaders), or programming AT89S51/52 or AVR chips like ATmega and ATtiny series, this programmer delivers fast, stable, and reliable performance . With an adjustable ISP programming speed of up to 8MHz, it supports both 5V and 3.3V target systems .

Equipped with a 500mA self-recovery fuse, this programmer protects your computer’s USB port from accidental short circuits on the target board . The 180° straight cable design allows for easy connection to development boards and is particularly compatible with standard vertical ISP header layouts on many target boards. The onboard power and programming status LEDs provide real-time visual feedback during operation .

Key Features

• USB 2.0 Full-Speed Interface: 12Mbps communication speed for fast program uploads, compatible with USB 1.1 and 2.0 .

• Broad Microcontroller Support: Programs 51 series (AT89S51, AT89S52, etc.) and all AVR ISP chips (ATmega, ATtiny series) .

• Adjustable ISP Speed: Auto-speed control firmware automatically tracks the target chip’s frequency (supports up to 8MHz programming clock) .

• Dual Voltage Compatibility: Supports both 5V and 3.3V target board logic levels, selectable via jumper on compatible versions .

• Onboard ATmega8A Controller: Built around the reliable ATmega8A or ATmega88 microcontroller with pre-programmed USBasp firmware .

• 500mA Overcurrent Protection: Built-in self-recovery resettable fuse protects both the programmer and your computer’s USB port from short circuits .

• Standard 10-Pin ISP Interface: 2×5 pin ISP connector for connection to target boards, with a 180° straight cable design for vertical header access .

• Reserved 6-Pin Header: Convenient 6-pin (MOSI, MISO, SCK, RESET, VCC, GND) interface for easy connection to target boards as needed .

• Self-Upgradable Firmware: The programmer can be updated to support future devices via the reserved programming interface .

• Cross-Platform Compatibility: Works with Windows (XP through 11), Linux, and macOS. Supported by ProgISP, AVR_Fighter, AVRDUDE, AVRStudio, and Arduino IDE .
