Specifications
- Slow SCK Option: Supports AVR targets with clock speeds below 1.5MHz.
- Overcurrent Protection: Built-in protection ensures safe operation.
- High Programming Speed: Up to 5 kBytes per second for efficient programming.
- Multi-Platform Compatibility: Works with Windows, Linux, and macOS.
- Power and Write Indicator LEDs: LEDs show real-time programming status.
- Onboard ATmega Chip: Central component enabling programming functionality.
- Dual Power Supply: Supports both 5V and 3.3V target devices.
- Cable Length: Comes with a 20cm connection cable.
Pinout of the Module
- MOSI (Master Out Slave In): Transfers data from USBASP to the target AVR.
- MISO (Master In Slave Out): Sends data back from the target AVR to USBASP.
- SCK (Serial Clock): Provides clock signal for synchronized communication.
- Reset: Controls AVR reset to enable programming mode.
- Vcc: Supplies power to the target microcontroller.
- GND: Common ground shared between USBASP and the target.
Supported Microcontrollers
Supports a broad range of microcontrollers:
- 51 series: AT89S51, AT89S52, AT89S53, AT89S8252
- AVR series: ATmega8, ATmega88, ATmega328, and others
Re-Programming Using an Arduino
The USBASP can be reprogrammed using an Arduino board. This allows firmware updates or modifications using the Arduino IDE, which includes tools like avrdude and avr-gcc without needing extra software.
Verifying
To verify USBASP operation:
- Check for a blue LED (power) and flashing red LED (activity).
- Ensure it's recognized by the operating system upon USB connection.
- If issues occur, double-check wiring and the programming process.
