The SBC83I(L) is a Single Board Computer (SBC) assembled with the PIC18F87J11 Microcontroller from Microchip, running at 48MHz. It has been designed to very easily be expanded, and has two 24 pin daughter board connectors, two 14 pin IDC connectors, three iMod ports and one sMod port.

The Microcontroller has 128KBytes internal FLASH and 3936 Bytes of internal SRAM. Additionally this boards has a 32MBit (4MByte) external FLASH, a 32KByte external SRAM, a 64KBit external EEPROM and a RTC with a Super Capacitor as battery. Note that the external FLASH, SRAM and RTC chips are not assembled!

There are plenty of Digital Inputs, Digital Outputs, Analog Inputs, PWMs and more available via two daughter board connectors and two 14 pin IDC connectors. Prototype daughter boards that make the signals on the daughter board connector available on prototyping space are available here.

The 3 iMod Ports can be used to add Presto iMod Modules. Presto iMod Modules are small boards, normally with a communication interface like RS-232, RS-485, 1-Wire, Ethernet and others. The sMod port can be used for adding serial peripherals, like SRAM, FLASH, EEPROM or others. A sMod module is a small board with I2C and SPI peripherals on it.

The SBC83I(L) accepts a wide supply voltage from 4V to 20V. It has a dual 3.3V and 5.0V power supply, making it easy to interface with both 3.3V and 5.0V devices. By default, the 5V supply is not used. If required (on daughter board for example), the supply voltage has to be from 7V to 20V. All chips on the board are 3.3V, but the microcontroller's I/O pins are 5.0V tolerant, allowing it to interface with 5.0V devices. Very high quality, brand name capacitors and regulators are used for the power supply, guaranteeing many years of trouble free operation.


  • Assembled with the Microchip PIC18F87J11 Microcontroller
  • 128KBytes internal FLASH memory for program and constant data
  • 48MHz Microcontroller Clock (12MHz crystal), with 12MIP Microcontroller execution speed
  • 3936 Bytes of internal SRAM
  • External 8Kbyte I2C EEPROM
  • 2.5V 0.5% Accurate voltage reference for ADC converter
  • Primary 3.3V Switch Mode Regulator
  • Secondary 5.0V Linear Regulator
  • Filtered analog supply to CPU for accurate analog measurements
  • Three Presto iMod Port for adding interfaces like RS-232, RS-485, 1-Wire or Ethernet for example
  • Daughter board connector with 48 pins for adding prototype board or LCD display
  • Two 14 pin IDC connectors with power and 8 I/O ports each Micro Match connector with I2C bus. Please note that this is a 3.3V I2C bus, and should NOT be used with our 5V serial LCD displays! Some users have however reported using a 3.3V I2C bus on our 5V serial displays successfully.
  • Red System LED on PIC port RB6
  • Pin header with jumper that can be mounted in 3 positions: Park, "C" or "F". Software can determine what position jumper is in, and for example use "C" position to restore default configuration, and "F" position to update firmware via bootloader.
  • 2.1mm power connector for standard DC transformer
  • Very low supply current of 10mA
  • Has an ICSP (In Circuit Serial Programming) connector - CPU can be programmed and debugged in circuit
  • Free fully functional MPLAB C18 C Compiler available from
  • Wide operating voltage range from 4.5V to 20V
  • Wide operating temperature of -40 to 85C
