Microchip PIC18F4550 USB Board US$20.00

Microchip PIC18F4550 USB Board

The SBC44UC is an embedded (PIC based) Single Board Computer (SBC) with a full-speed USB interface and is assembled with the Microchip PIC18F4550 microcontroller. It has been designed to work with the free Microchip USB Software. This includes software for developing:

  • Human Interface Device (HID) class firmware
  • Communication Device Class (CDC) firmware
  • Mass Storage Class Firmware
  • Microchip Bootloader
  • Microchip Custom Driver

The SBC44UC can be powered by the USB bus or by an external power supply. A unique relay circuit is used to select between USB or external power which ensures that full USB voltage is available to the SBC board and possible user applications. Since the voltage supplied by the USB bus is specified between 4.75V to 5.25V, it is very important that the full voltage is obtained, considering that many electronic components require a minimum of 4.75V.

Microchip PIC18F4550 USB Board Features

  • PIC18F4550 CPU
  • 33 general-purpose user-programmable I/O ports
  • 13 user-programmable, 10-bit Analog-to-Digital converters
  • 2 user-programmable, 10-bit CCP units that can be used for PWM or Capture/Compare functions
  • 1 USART
  • 2 Comparators
  • One 8-bit and three 16-bit timers
  • 32k Bytes of user-programmable Flash memory
  • 2048 Bytes of RAM
  • 256 Bytes of non-volatile internal EEPROM; has socket for additional external EEPROM chip
  • Socket for adding an MCP23008 I/O expander
  • Red user LED on PIC port RB6
The Micro-MaTch connector allows you to use this board to drive one of the LCD2S- Serial LCD displays found in our LCD Displays category. Multiple I2C devices can be daisy-chained together using the Micro-MaTch connector.

Build an Enclosed System

Using the Compact Daughterboard connector, this USB board can be used as a control module for the Input-Output-Relay Board, which comes in a sturdy enclosure.

You also can make a fully enclosed system by connecting this board to the Add-on Prototyping Board with 10 I/O Ports or the Add-on Prototyping Board with 24 I/O Ports, each of which comes in an enclosure.

Optional Daughterboards

This board features a connector for either attaching a daughterboard, or using this board as a daughterboard on a larger add-on board.

Optional Add-On Frontend Boards

This board also has Frontend connectors installed (not shown in image above) which allow it to be expanded with the following optional add-on boards:

Optional In-Circuit Serial Programming Adapters

PIC ICSP Board Connector to DIL Adapter Set, In-Circuit Programming Adapter Set for connecting this PIC board's ICSP connector to out-of-circuit PIC chip programmers with a DIP/ZIF socket.

PIC ICSP Adapter, 6-pin Single Row to RJ12 and 2mm 2x4 Header, In-Circuit Programming Adapter for connecting this PIC board's ICSP connector to the debuggers programmers with RJ12 jack or single row square post headers.
