Description

The SBC83I 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.

Modtronix provides many free example projects written in C. They are written for the free Microchip MPLAB IDE and MPLAB C18 C Compiler.

The Microcontroller has 128KBytes internal FLASH and 3936 Bytes of internal SRAM. Additionally this boards has a 64KBit external EEPROM. It also has space for a 32MBit (4MByte) external FLASH, a 32KByte external SRAM, 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 Modtronix Presto iMod Modules. Presto iMod Modules are small boards, normally with a communication interface like RS-232, RS-485, 1-Wire, Ethernet and others. For currently available iMod Modules, click here or contact us to request a custom iMod Module. When purchasing iMod Modules together with this board, they will be discounted 50 to 60%! For details on iMod Modules and Ports, click here. See "Available Options" at the bottom of this page to add iMod Modules to this boar. For example, to order a SBC83I board with an Ethernet Port and two RS-232 ports, select the in28J60 module as an option for iMod Port 1, and the im232M RS-232 module for iMod Port 2 and 3.

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 accepts a wide supply voltage from 4.5V to 30V (can be extended to 40V on request). 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 30V. 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. The 3.3V power supply is a high quality 500mA DC/DC Converter from National Semiconductors, with shielded Inductor and surge protected capacitors. Input Capacitors are high quality, long life, surge protected types as recommended by National Semiconductors. A linear regulator is used for the 5.0V secondary supply.

This board is assembled with very high quality, brand name components! Our goal is for this board to work error free for many years. For this reason, we do not use cheap components, or stress components to the limit of their capability! The quality of assembly, and reliability of components used sets this board apart from similar competitor products!
