Summary of PIC 18F – 28 PIN PIC Development Board

This article describes a versatile, cost-effective development board for Microchip's 18F-28 pin microcontrollers. It features a ZIF socket for easy chip removal, a marked ICSP connector for programming, and a plug-in crystal with jumpers for configuration. The board includes a bridge rectifier for polarity protection, a power-on LED, and a 7805 voltage regulator. All port pins terminate in headers to supply external devices, though users must manage current limits as no short-circuit protection is provided.

Parts used in the PIC18F Development Board:

  • ZIF socket
  • ICSP connector
  • Jumper J1
  • Jumper J2
  • 20 Mhz Crystal
  • Jumper J3
  • Bridge rectifier D2
  • Power On LED D3
  • Voltage Regulator IC U2 7805
  • Header connector
