8051 Development Board with ZIF Socket – Multi-Programmer Compatible

Overview

• With this powerful and user-friendly 8051 Development Board, you can prototype and develop projects using any 40-pin 8051 microcontroller.
• The board features a Zero Insertion Force (ZIF) socket to protect your MCU during repeated use, an onboard RS232 driver (MAX232) for easy PC interface
• Supports  bootloader flashing support for popular ICs like Nuvoton chips , ISP connecter to program 89S51, 52,  using AVR isp programmer 
• Its built-in bridge rectifier ensures compatibility with both AC and DC 12V power adapters, making it flexible and classroom/lab-friendly.
