GCPUx : General Purpose PIC CPU

Project by:

Tony / I2TZK, Frank / K7SFN , Dinesh / VU2FD

GCPUx is an expandable CPU and Graphic LCD project which has provision to "add" a "project" board to create a full function amateur radio station accessory.

Advantage of "GCPUx" concept is a possibility to add new project board, change processor code and have a new working unit for your ham station. 

Present add-on board designed and will be available are: PM5 (RF Power Meter), SWM5 (SWR Meter) , FC5 (Freq Counter+RF Meter) and AAZ5 (Antenna analyzer)

Note: GCPUx is not compatible with AAZ-0914A Antenna Analyzer (and other "Infinity" projects). A small interface board and change in firmware is required. update FW and interface board are under development.

GCPUx has following design task:  

Simple single Micro Controller with built-in A/D converter (PIC18F4550)
 
Support add-on board: PM5, SWM5, FC5, AAZ and more...
GCPUx:
Operates on DC12V,  USB or Internal battery*.
 
Provision for 7.2V NiMh/NiCad Battery on roof for Standalone operation
 
Bluetooth operation for smart phones (Depend on FW)
 
4 A/D channels and 4 Digital channels ready for Project Board
 
One Frequency Measurement Channel.
 
Simple 4 Button Menu operation
 
Graphic LCD 128X64 with backlight
 
Battery board uses MAX712 for charging (Option)
 
Free Powder coated metal cases
