	Figure 6. Needed patches from version A2 to A3. PWM for steering servo in RC mode now moved to timer FMT3 on pin 29 (old connection to pin 5 must be cut). Actuator 2 encoder A also connected to pin 5 (for interrupt), and actuator 1 encoder B also connected to (free) pin 30 - also for interrupt (annotated image has error Act 1<->2). The last 2 maintains connection to DAC pins and pull-up resistors.		Figure 6. Needed patches from version A2 to revision B.
