Description
Its a 2.4-2.48 Ghz bluetooth testing device. It have 2 transmitters and a nice interface.
If you want a quick look at it in action look at my tiktok: TikTok
!!!!THE BOADRD WILL BE UPDATED SO PLEASE DOWNLOAD THE NEW ZIP GERBER FILE!!! (current newest = update 1.2)
The project is still on going and will be completly done soon
The code will be shared on github for free when its tested and done with updates comming.
If you have a 3d printer you can print the case for free if you want to make it look like this:
i think the design is pretty cool and its super easy to assemble everything just click into place
In this photo i made myself a 16x31x3 mm peice of plexiglass to protect the screen and make it look better. the plexiglass have a little peice of plastic around it so it dont stick out and stuff.
The buttons is also hid under some pads and the boot button also. i havent made it for the reset button because you can just turn it off and on again.
On the back there is a heatsink i use this one heatsink link and these pads pads link if you have your own the heatsink is 14x14x any height over 4 mm.
all the 3d files will be under here and on github.
you can modify the code yourself for your needs where i have added these attachment pins in the top where you could put an IR led to test TV's
i have made it so there are some breakout pins if you want to make your own attachments for the project :)

RF modules you need 2 |
there are 3 options to the transmitter. The NRF24 l01++ its cheap low power(more battery time) only 1mW 0dBm output The E01 ML01DP5 its 100 times more powerfull than the NRF24 its more expensive and use 100mW power and is 20dBm output The E01C 2G4M27D- 500 MW is the best it use alot of power and there for dont have that much on time but 27dBm output |

| capasitor you need 2 | capasitor link | any capasitor over 50 uf will do it |
|
Buttons any 6x6 will do you need 2 of these |
button link | |
| switch (for power) | switch link | |
| 2x 10k resistor | resistor link | or anything over that will prop work its for the voltage devider so you can see the battery % |
| BATTERY | battery 124050 lipo link | you can really use any 3.7 v lipo to be honest but here are one you can use (or the one i use) |
| stepup | booster module link | REMEMBER TO CUT THE 5V PIN SO IT GIVES 5V |
| charger module | charger module link | for charging the battery |
