Farhan's New uBITX Version 6!

I'm currently reviving my "version 3" uBITX and putting it on CW.  It sounds and works great, but when I saw this I realized that I am falling behind.

Here is what it looks like :
And of course, yoiu can buy it on hfsignals.com. The shipping will happen from Tuesday onwards. We have a limited supply of the first 200 boards. The rest is for after christmas.

The most important thing about this revision is that the  Radio circuitry is almost unchanged. We have incorporated the connectors on the PCBs. So, this kit needs none of the confusing soldering. You snap in the TFT Raduino onto the main board, plug the power and antenna from the back, snap on headphones, plug in the mic (supplied with the kit) and off you go!

It is offered in two kits now : The basic kit (150 USD) is without the box (like old times) but with a microphone and two acrylic templates for the front and back panels. 
The Full kit (199 USD) has the box with speaker, mounting hardware etc. Both are described on the website. 

Now, about the TFT display: 

For those who are using the 16x2 display and you would like to upgrade, you will have to do three things:
1. Add a heatsink to the 7805 of the raduino
3. Grab the new Arduino sketch from https://github.com/afarhan/ubitxv6

Background : 
I have been hacking away at adding a TFT display for the Arduino for sometime. Finally, I managed to do this with a really inexpensive 2.8 inch TFT display that uses a controller called the ILI9341. The display update is slow but, clever guy that I am, the display very usable. it uses the same pins that earlier connected to the 16x2 LCD display. This display is available everywhere for a few dollars. 


  1. Holy wa! FB Farhan! I need to troubleshoot my V3 before getting one but it is tempting. Thanks for sharing Bill.

  2. Wwwwhhhhhhaaaaatttttt! Take my money.
