Product overview
The Rctimer AIOPIO Board provides input/output expansion for AIOP Flight Controller versions 1.0, 1.1 and 2.0, allowing LEDs and other modules to connect to the controller. Its architecture combines 0.1-inch pitch serial1/2/3 connections, analog input ports 0/1/2 for airspeed and voltage/current sensors, a ULN2003A LED driver with an output port, and a FrSky telemetry output. The external power port includes reverse polarity protection. The supplied hardware consists of an AIOPIO board and connection cables.
The board measures 50 × 25 mm, with fixing holes spaced 45 mm apart and a hole diameter of 3.1 mm. The package includes one board and two 50 mm 1.25-8Pin cables. Selection jumpers SJ1, SJ2 and SJ3 route ULN2003A inputs IN7, IN6 and IN5 to AIOP A1, A2 and A3 respectively. SJ4 links the FrSky telemetry output to AIOP Serial 0, while SJ5 provides external power input for the AIOPIO board. All selection jumpers are unsoldered by default.
