Here is the sound board kit for your T-21 or whatever use you would like to use it for. The video explains what comes with the kit and there are also pictures.
The sound chip comes pre programmed so there is no way to add to it unless you program another chip and add it. The chip comes off easily. If you want to program the entire board there are three little holes on the side of the board that are used to do this. You will have to write your own code. The code I have written is very specific and controls many things on the board. The board can be reprogrammed if you know how.
If you chose to program the board I cant be responsible if the board stops working.
If you want to change the color of the led light just pull the led light out and put your own color in. You can even change speakers for bigger or smaller to fit what ever you are building.
The board is designed to have plenty of power.
The kit will include:
1. Sound Board and parts
3. Mounting parts like I mount the kit
4. Charger cord to recharge the battery
Kits are 110.00 shipped in the U.S. Insurance Included
Kits are 130.00 shipped Everywhere Else Insurance included.
These are the same kits that are mounted in my T-21 builds.
Feel free to ask any questions. I will help in any way
