Assemble BBBmini

Step 1: Solder resistor R4 and R5.

For 3.3V RC input signal use R4 = 0Ω (bridge) and R5 = open (see picture)

For 5V RC input signal use R4 = 1kΩ and R5 = 2kΩ

Step 2:

Solder resistor

R1 = 120Ω

R2 = 1kΩ

R3 = 2kΩ

R6 = 20kΩ 0.1%

R7 = 10kΩ 0.1%

R8 = 20kΩ 0.1%

R9 = 10kΩ 0.1%

to the bottom layer.

Step 3:

Solder CAN transceiver on the top layer

Step 4:

Solder male pin-header on top layer

P1, P2, P3, P4, P7, P10, P11, P12, P13, P14, P15, P16, P17, P18, P19, P20, P21

Step 5:

Solder C1 and C2

Step 6:

Solder female pin-header P5 and P6 on top layer

Solder P5 and P6

Step 7:

Solder male pin-header P8 and P9 to bottom layer

Step 8:

Solder male pin-header to bottom layer of GY-9250 and GY-63

Step 9:

Mount spacer to BBBmini

Step 10:

Mount GY-9250 and GY-63

Finish! BBBmini is ready to use for Copter, Planes or Rover.
