ITEM NAME:USB ISP ASP Programmer USBASP USBISP for 51 AVR Series MCU Microcontroller Board Product Description Description: HW-437 USBASP USBISP AVR Programmer USB ISP USB ASP for 51 AVR MCU M icrocontroller Board Features: The module is an 8*8 red dot matrix driven by the HT 16K33. The communication type is I2C, which allows it to be connected for Arduino and other microcontroller boards. Specifications: Input voltage: +4.5-5.5V Input type: Digital signal Interface terminal: XH2.54X4 Pin Definition: G_ Ground V-Power D (SDA) - Serial Data C (SCL) Serial Clock size: 60*15*3mm/2.36*0.59*0.12" Module weight: 35g Instructions for use: The data communication interface of the module is 12C. As long as the MCU has the interface, it can realize its control. You need to write codes by yourself for specific implementation. Notes: 1. There may be slight size deviations due to manual measurement, different measuring methods and tools. 2. The picture may not reflect the actual color of the item because of different photographing light, angle and display monitor.
