Description: This is simple prototype board for development of USB application with PIC18F4550 microcontroller. The power of the 18F4550 is that it has USB hardware built into it so that you can program different USB stacks directly onto the IC. Microchip provides these free USB solutions for their microcontrollers which are openly available. The USB HID Class firmware can help you to build a mouse or other Human Interface Devices for Windows, USB CDC Communication class device, USB Mass Storage firmware (add your own USB disk drives to your computer), USB-to-RS232 driver. The prototyping space allows you to easily add on sensors, relays and other peripheral devices to interface to USB. The board can take power from USB or from an external supply with small jumper selection.

Dimensions: 100x80 mm (3,9x3,15")

Features:

  • ICSP/ICD connector for programming with PIC-MCP, PIC-MCP-USB, PIC-PG1,PIC-PG2, PIC-PG3 or PIC-PG4 and programming and debugging with PIC-ICD2, PIC-ICD2-POCKET, PIC-ICD2-TINY
  • USB 2.0 type B connector allow board to be interfaced to PC host
  • PIC18F4550-I/P is included
  • Quartz crystal 20MHz
  • LED connected to RD3 through jumper
  • User button connected to RB4
  • Reset button
  • Power jack with diode bridge can be powered with AC or DC power supply
  • 5V regulator
  • Extension slot on every uC pin
  • Grid 100 mils
  • GND bus
  • Vcc bus
  • Four mounting holes 3.3 mm (0.13")
  • FR-4, 1.5 mm (0.062"), green soldermask, white silkscreen component print

  • i purchased a pic18 development board.Which Ccompiler should be used for it?Do i need to install the USB bootloader?If yes then which? I am new to this,can anyone guide please

    Thank you in advance

  • I just purchased the development board and don’t know how to get started. Here’s what I’ve done so far: 1. Switch the PWR jumper pins to USB 2. Connect a USB cable to the board and PC ( I see a blinking LED) 3. Download the C source of the USB bootloader (AN1310) 4. Run the Bootloader.

    Problems I’m facing: 1. With the board connected, AN1310 shows that it cannot connect to COM1. I don’t know how to go about changing the port. 2. I don’t know how exactly to flash a program onto the board. 3. How do I go about programming? I want the development board to function as a Mass Storage Device

    Any help is greatly appreciated

    • I went ahead and purchased a pickit2

      • I recommend to upload the Pinguino bootloader. Look in google for pinguino proyect. It is an Arduino enviroment for these kind of pics. You can program the PIC via USB and use the same languague Arduino has.

  • Will I need to order a programmer aswell to program this? Or can it be programmed by usb by default?

  • Disregard

  • Can I order this board without the PIC? I want to use a different MCU and I don’t need this 4550

    Best,

    • Unfortunately, we can’t do custom orders, so you can only this board as-is with the MCU included. However, we do have another 40pin PIC development board that comes without a MCU included, found here.

  • Looking at both the usbdrv.c and the boot.c files, it looks like its based from the Microchip’s Bootloader App Note AN1310 (please see http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1824&appnote=en546974) for High-Speed Bootloader for PIC16 and PIC18 Devices.
    For the Host PC app, here is the URL http://ww1.microchip.com/downloads/en/AppNotes/Serial%20Bootloader%20AN1310%20v1.03.exe
    I hope this helps

  • Is there a tutorial for the USB Bootloader? I looked through the C source linked above, but no documentation is provided.
