Description: This is an easy to assemble, through-hole kit version of the popular UBW board. This is a spectacular little development board featuring the PIC18F2553. Based on the work of Brian Schmalz, the UBW is a small board with a command interpreter for basic input and output control. When attached to a Windows/Max OS X/Linux computer, the UBW will show up as an RS232 Com port! You control the individual I/O pins on the PIC through simple serial commands. This is a kit and includes a pre-programmed 18F2553 and both male and female connectors so you can choose which connector you would prefer.

The 18F2553 comes pre-programmed with a USB bootloader. This means you can create HEX files using any compiler or assembler (C18, CC8e, SDCC) and then load that HEX file onto the PIC without an external programmer - directly over USB! Power is obtained over USB.

Please download the Microchip USB Bootloader below. Please see the UBW home page for more information.

Note: This product is a collaboration with Brian Schmalz. A portion of each sales goes back to them for product support and continued development.

  • What about the same, but with the PIC32?

  • The ICSP header is a nice reason to have the through hole version. But those super-bright LEDs are KILLING my eyes! I replaced them with diffused ones of the correct colors.

  • You should update this web page and the assembly instructions to use the PTH V2 board which has the ICSP connector installed differently than in the pictures and the assembly drawing.
    Unfortunately the ICSP connector is different than either of my programmers which use a 2x3 connector.

  • All i can say is great work fast too. i look forward to putting these together.

  • I am using an ICD3 with DEV-08108 board.. I fliped the connector and everything works fine now.

  • I think the ICSP is on backwards in the picture.. You guys might want to change that. I soldered mine in the way it is in the picture and it failed to program.. I checked with my meter and the entire thing was on backwards..

    • I guess it depends upon what you’re connecting to the ICSP connector. I use PICKit2 and now PICKit3 for my programming/debugging, and I can easily align pin 1 of the programmer with pin 1 of the UBW ICSP connector.
      What programmer are you using that can’t be put on properly?

  • More of the obvious:
    This board has mounting holes and the USB-B “non micro” connector if you prefer either.

  • Plus, free headers!

  • What is the benefit of putting together the UBW kit instead of buying the populated board?

    • You mean aside from rescuing RC2 so you can use it for PWM, as it should be?
      :)

    • Good question - mostly for modifications and repair. If you blow the PIC (motor EMF throw-back, over draw, etc), it is much easier to replace a DIP.
