HGLRC Specter 15A ELRS AIO is a board containing a flight controller, 15A ESCs and a 2.4GHz UART ELRS receiver. The board can be powered by 2-4S Lipo batteries, making it suitable for 2-3" Toothpicks and similar lighter drones. The board uses a flight controller based on the F411 processor and MPU6000 gyro. There is also a 5V BEC, 8MB of memory for the blackbox and a current sensor. The ESCs use Bluejay firmware and can handle current up to 15A. The ELRS receiver is connected via a UART, so its functionality is not limited as with SPI receivers. An external antenna is connected to the receiver via an IPEX1 connector to ensure full range.
