Summary of Multipurpose 18 PIN (16F628A) Microcontroller development board
This 18-pin development board supports the Microchip 16F628A microcontroller, featuring a Relimate header for port access, an ICSP connector for programming, pull-up resistors on MCLR and RA4, a reverse polarity protection diode (D1), a power-on LED (D2), and a 7805 voltage regulator (U2) for stable 5V output. It accepts 7–12V DC input and can supply power to add-on cards, though users must manage current limits as no short-circuit protection is included.
