USBASP download board is a AVR or 51 single-chip programming tool specially designed for friends who do not have serial or parallel ports on their computers. It adopts speed adaptive technology, can provide 5V/500mA power supply current to the target board, and can choose through the jumper cap. PCB is designed according to the high-speed board standard, stable and reliable.
The USBASP download board is a USB‑based programmer designed for AVR and 8051 microcontrollers. It uses an Alnega8 chip and speed‑adaptive technology, providing a compact 10‑pin ISP connector and optional 5 V/500 mA power to the target board.
The manual covers driver installation on Windows, jumper settings for programming speed and power supply, and lists supported microcontroller families. It also includes the hardware schematic, a parts list, and references to compatible programming software such as ProgISP and AVR_fighter. This manual is written in Chinese.
| Supply Voltage to Target | 5 V / 500 mA |
|---|---|
| Download Connector | 10‑pin ISP standard |
| Controller Chip | Alnega8 |
| Programming Speed | Speed‑adaptive (auto) or slow mode via jumper |
| Protection Circuit | Self‑resetting fuse on USB power |
Set jumper J2 (or JP2) to the closed position to enable 5 V/500 mA output; open the jumper to disable power if the target board draws too much current.
