The USB PIC Interface Board contains a Microchip PIC18F4455 microcontroller with USB interface. Most of the microcontroller ports are available on the standard HDC10 connector. The chip is preprogrammed with our HID compatible (no drivers are necessary) bootloader. The board is ideal to build any USB compatible hardware.

Push Button & LED Board

The relay board is useful for switching relatively high loads (lamps, motors, etc.) up to 5A@30VDC. It has four separated channels with LED indicator. The board contains all necessary driving electronic for the relays but an external 12VDC power supply is necessary. One digital port with 4 output line must be connected to the HDC10 connector of the board. If switching of eight channels is required two boards can be daisy-chained.

The jumper board is simply a cross connection board for DSB system. With this board the pinout of and HDC10 connector can easily be changed. Mixing or splitting HDC10 lines is also possible. The power supply connection of HDC10 connectors can be enabled or disabled using standard jumpers. The cross switching connection can be easily changed using connectors and wires or can be fixed with soldering wires into the required place. Beside cross connection matrix the board contains two prototype areas with 0.1” raster of 1mm holes.

The purpose of this board is to provide stabile 5Volt supply for other REP10 boards up to 1Ampere consumption. The board has two different configurations. In the first case the board is supplied from DC voltage via DC plug. In this case only the reverse polarity protection diode must be assembled. The other configuration is when the board is supplied from AC voltage via the screw terminal. In this case a rectifier bridge must be installed. The board has two HDC10 connectors, both of them connected to the 5V supply. The I/O pins of the connectors are connected via the cross connection matrix.

The 4digit LED display board is ideal for digital clock application or a general purpose learning tool for microcontroller development. The board contains 4digit 7segment red LED display with colon at the middle. It also contains eight red LEDs (separated into two four led groups), one speaker and three pushbuttons. For the operation only two 8bit I/O ports are necessary. Optionally the led display can be replaced with a 4digit display with dots between the digits (instead of semicolon at the middle). In this case the display can be used to display generic numbers for volt-, amps- and multimeters.
