Where could he take the uBITX from here?
Well you have only got to blink these days and things always get updated very quick!
The new V6 uBITX could be the wolf that eat the cat meooow!
Gone is the two line 1602 display, a new 2.8" LCD touch screen is it's replacement. No soldering required is part of the new uBITX sales statement, is this a rig that now plugs together like lego? Gone are connections that once had to be soldered with wire to the 3.5mm sockets for mic, key etc. These are now attached to the new V6 PCB, along with the variable resistor for the volume control, even the encoder doesn't need a soldering iron anymore it comes already attached and soldered up with a plug ready to push into the revised board.
There are two flavours of kit, as before you can just buy the tested PCB kit with raduino, display, hardware and stuff it in a box of your choice (Basic kit) . Or there is now a second choice of a professional predrilled case, (Full kit) which really takes the uBITX to retail standard and looks the part. Both kits, even come with a fist microphone ready to plug in and a speaker for those that purchase the full kit.
Those that have purchased V5 PCB can upgrade to the 2.8" display and update the Raduino firmware, and should read these notes:
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
2. Buy https://www.aliexpress.com/item/32815224002.html?spm=a2g0o.productlist.0.0.3b9548336X8T43 and hook it up as per http://www.hfsignals.com/wp-content/uploads/2019/12/raduino_tft.pdf
3. Grab the new Arduino sketch from https://github.com/afarhan/ubitxv6
I also found the displays are available on ebay.
