MINI APM flight control board V2.62
MINI APM V2.5.2 is based on the standard APM V2.5.2 from which we did some improvements, MINI APM
V2.5.2 is a minimum size control board and it also keeps the connection ports and original function of the standard
APM V2.5.2, the following is about its improvements:
1) The connector ports of ESC and airspeed meter (or supersonic wave) are in 90 degree angle ( 9 pieces of 2.54mm
3P port in total: OUT1, OUT2, OUT3, OUT4, OUT5, OUT6, OUT7, OUT8, A0), they are high quality gold-plating
ports;
2) 8 pieces of 2.54mm 3P ports to receiver are canceled, 2 pieces of 1.25mm 5P port are replaced instead.
3) The port for voltage and current sensor is changed from vertical way to horizontal way (order of ports keeps
unchanged).
4) The port for 3DR Radio is changed from 1.25mm 5P vertical terminal to 1.25mm 4P horizontal terminal instead.
5) ISP port of ARMEGA2560 is changed to 1.00mm 6P horizontal terminal.
6) The ports for gimbal servos and analog input are changed to 1.25mm 5P terminal.
7) The ports for GPS and outside compass are all changed to 1.00mm 4P horizontal terminal.
8) Input and output for Ports of GPS, outside compass, input port for receiver signal and USB are in the same
direction.
MINI APM V2.5.2 Flight board mechanical parameter:
1) Size: 50.0*32.0*8.2mm (not including servo connector port), 58.6*32.0*12.0mm (including servo connector
port)
2) Hole size for installation:Φ2.0mm
