Home of the ARiUSB (patients pending)

Small footprint Allstar USB radio interface with ACT, PTT, COR Led's, 3 GPIO and CM119 Audio Chip.
Input USB Power filtering.
Link for getting the other GPIO pins working. Thanks Guys!
The original page is no longer there please see the link to that page can still be seen.
Click on the Dec 31, 2017 link on the calendar for that page. 
 Let me know how it works out for you!

The COR Led is used for software troubleshooting the COR signal software controlled to help you with problems.
USB power is filtered with Hi, Low pass filtering. With new chip using the CM119A sound chip like most sound fobs bought,
bought to be modified, this is kind of middle road, simple, small and inexpensive. Designed after a modified Audio Fob.
Each one sent out is 100% functional tested to ensure they work as intended!
I am also testing the same circuit with the CM119B that does not use an external Osc. I'll let you know how that going soon!

When used with the right software all settings are software controlled with little to no adjustments.
Knowledge of Electronics, Computers and Linux is required to interface this device.
If you'd like to solder your own board and parts I'm working on putting an SMD kit together.
Maybe $15 + shipping. Ask if I have them. Let know what you think? Maybe after the New Year!

**Coming soon, Radio-less Node board that will plug directly on top of the ARiUSB allowing you to connect to an external local speaker
and Mic on your radio bench with your other equipment. Stay Tuned! - I'm going to be back on track! Had a ruff dip. Stay tuned!(7/20/18)
