USBtinyISP is an AVR ISP programmer based on the USB interface. Officially supported by the Arduino IDE and compatible with USBtinyISP, it can burn the Arduino bootloader onto chips and program any Atmel AVR microcontroller. The programmer provides a 5V power supply to the target board. To power the board via ISP, close the SJVCC jumper on the programmer. It supports uploading sketches and burning bootloaders on AVR-based boards, including Arduino boards. Using an external programmer allows you to upload sketches without a bootloader, freeing up additional flash memory. It can also restore a corrupted bootloader or install one on a bare ATmega microcontroller for USB-serial sketch uploads. Supports ATTiny45 and ATTiny85 microcontrollers. Supply voltage: 5 V Microcontroller: ATtiny44 Connection to computer: Micro-USB Connection to target board: ICSP Board size: 23 × 14 mm (approx.) How to use: – Connect the ISP programmer to the target board’s ICSP header. – Align the connector orientation using the white dot marker. – Open the Arduino IDE, select the correct board under Tools > Board. – Select “USBtinyISP” under Tools > Programmer. – Choose Tools > Burn Bootloader to begin. Bootloader programming for ATmega328 takes approximately 10 seconds. Color: As shown Material: PCB Package contents: 1 × USBtinyISP Programmer (not 10 × Miniature Encoder Module)
