DroneBridge is a system based on the WifiBroadcast approach. A bidirectional digital radio link between two endpoints is established using standard WiFi hardware and a custom protocol. DroneBridge is optimized for use in UAV applications and is a complete system. It is intended be a real alternative to other similar systems, such as DJI Lightbridge or OcuSync.

C99 firmware core for a 16-series LFP pack. Independent charge and discharge FETs, cell protection, coulomb SOC, and the current and voltage limits an inverter follows. Passive balance runs for 1.0 s, then 200 ms off, so the fault wait finishes on an unloaded sample. No RTOS, no heap. The AFE driver and fieldbus stay on your board.
