CB40 V3 / CB40 v3 Prototype
« on: February 11, 2021, 05:29:15 PM »
Here is a sneak preview of the CB40v3 which is off to the fabricators to get some prototypes made. It has TX detect so will allow split channel/frequency, additional memory channels, support for color RGB OLED's, 7 Segment LED display support from 2-6 digits and a host of other things. The Atmel 328P in the v1/v2 has been replaced by the Atmel 1284P giving me 4 times memory to play with and add features. It is exactly the same size as the v2.

CB40 v2 / CB40 v2 project
« on: June 25, 2020, 10:47:41 PM »
This has been worked on hard by peter and its going to be awesome, this version can have 2 typed of displays the OLED or 3 7 segment display, so for you that want it to look as close to stock the 7 segment display if for you, or if you want to be different you can run both OLED and 7 segment displays at the same time.

the CB40 v2 kit dose not come with the 7 segment display, thats a add on you pay extra for.

i will add some photos and videos soon.

this Version of the CB40 is a kick ass upgrade, that nothing out there is better or can even come close, 100s of man hours has been put into not only the design but the Coding
