USB Host Controller Board V2.4 

The USB Host Board is based around the Microchip 24FJ64GB002 microcontroller which contains a built-in full-speed USB host controller. This allows the board to interface with and control any USB slave device - flash drives, keyboards, digital cameras, PS3 game controllers, and much more!

The USB Host board is designed to be as simple to use as possible. All of the complex USB programming is contained in the microchip so there is NO USB coding required in your application. This saves valuable programming space and saves you from having to code and debug USB interface routines. The onboard microcontroller has a bootloader and is easily updatable with any of our free USB Host driver software.

Features

  • Complete USB Software onboard. No USB coding required on your microcontroller
  • Simple UART and I2C interface
  • Easily updatable software includes {{INCLUDE:usb_host_firmware.tpl}} See Related Products tab for more details on software available
  • Easy to update the software using simple serial connection and built-in bootloader
  • Works with both 5V and 3.3V systems
  • Real Time Clock
  • One-board 3.3V 250mA regulator with output
  • Green POWER LED
  • Red LED indicates bootloader active or Error
  • Blue LED indicates device plugged in and accepted
  • All pins are 5V tolerant so will work with 5V and 3.3V microcontrollers.
  • Board size 38mm x 27mm

External connections available on the USB Host board

  • 5V power supply
  • 3.3V output (250mA)
  • RX and TX
  • SDA and SCL for I2C communication (check specific firmware for implementation)

Downloading Software to the board

You can write your own software for the USB Host Board or you can download one of our free software applications. Downloading software to the board does not require a specialist programmer because it has a bootloader already installed. 

New software is easily installed over a serial RX/TX connection, so you will need an appropriate connection to your computer. We recommend the FTDI Basic breakout board but there are many similar boards and cables available.

Connect up the power (5V) and GND lines, then connect the RX on the Host board to TX on the FTDI board and TX on the Host board to RX on the FTDI Board. You are now ready to install the new software.

To load the new software we use the free ds30loader application. This works with the bootloader on the Host board. Run the ds30loader application and...

  • Select the hex file you wish to upload
  • Set the device to be PIC24FJ and 64GB002
  • Set Baud rate to 115200
  • Set Port to your serial port connection

If you are having problems downloading the ds30Loader program from the authors website, you can download a copy from our website here.

Once you have these setup we just need to click the Write button (just below the Commands menu) and the software will attempt to connect to the bootloader and upload the new software. In order to make the bootloader active though we need to reset the board by briefly pressing the reset button. This needs to be done as short time after clicking the Write button. The easiest way to do this is to hold down the reset button, click 'Write' within the ds30Loader program, then release the reset button.

See the screenshot below for an example.
