DIY EAF project for Askar FMA 135
Based on Arduino Nano, with myFOCUSERPRO2 "myFP2M_ULN2003_336" open source code Ascom Compatible
Motor :5V 28BYJ-48
Stepper control chip: ULN2003
Prototyping board: 20x22mm
Belt: GT2-260, Belt Width 6mm
Pulley: GT2 12 teeth 5mm
Bolts:
2 x M5x10
2 x M4x8 with washers and nuts
4 x M3x8
Some tips for connecting wires, this is not clear on the pictures...
The Red of the 28BYJ-48 motor is connected to the bottom right pad of the ULN2003 chip (ULN2003 COM).
VIN from the arduino is also connected to the bottom right pad of the ULN2003 chip (ULN2003 COM).
GND from the arduino is connected to the bottom left pad of the ULN2003 chip (ULN2003 GND).
Hope this help :)
