Deprecated; there is now a newer version of this design.

This is a test Bluetooth Nano 33 BLE driven Arduino module to handle quad deployment and read several inputs at the same time.
This module is working well and has flown several times. Since first design of software, I have increased the performance of packet transfer to over 20 times a second. It could be faster but I want to test for falloff of battery time before I do so. Each channel can handle up to 2amps load when engaging igniter. All tests have proven that is more than enough for standard fireworks based igniters or Q2G2 even when two or three are wired in parallel (you should use series for fireworks based, that's how they are designed to work.)
The battery for this unit appears to last as long as one attached to stratologger.
My software is fault tolerant. If the battery is low and fails to keep the computer online during deployment, the ardunio computer will simply reboot and will be ready within less than 10 seconds.
This device ties in well for multi-staging, servos, etc. Testing as proven high reliability and I can't imagine me going back to any type of wired connection between phone and remote deployment.I'll end up swapping the USB based controller in my launcher to using the same type of device, except beefed up to handle massive amps per channel.
