INTRODUCTION

This board was designed to allow easy interfacing of embedded projects to computers with USB. F232 USB-to-RS232 converter IC creates virtual "COM" port to the PC and you can easily send and receive date using the good old fashioned RS232 interface in the PIC microcontroller.

FEATURES

• Supports all 28 pin PIC microcontrollers
• ICSP/ICD connector for programming with PIC-MCP-USB, PIC-MCP or PIC-PG1,PIC-PG2, PIC-PG3, PIC-PG4 and debugging with PIC-ICD2, PIC-ICD2-POCKET, PIC-ICD2-TINY(* for the PICs with ICD support) PIC16F87X is also supported by the low cost PIC-ICD1
• USB to RS232 FT232 converter
• I2C EEPROM socket
• takes power from USB no need for external adapter
• power supply filtering capacitors
• Quartz crystall oscilator circuit 20Mhz
• reset button
• general purpose push button connected to RA5
• status LED connected to RA2 via removable jumper
• DIL28 microcontroller socket
• extension pin headers for each uC pin
• four mounting holes 3.3 mm (0.13")
• Grid 100 mils
• GND bus
• Vcc bus
• FR-4, 1.5 mm (0,062"), green soldermask, white silkscreen component print
• dimensions 100x80 mm (3.9x3.15")
