12. Auxiliary processor I/O block

This block contains the auxiliary processor’s A, B, C, D/RX, and TX lines, as well as several connections to GND

and VCC. You can solder in either the 3×7 male or 3×7 female headers here, or mix and match genders using the

other provided headers.

13. Current sense outputs

If you want access to the analog voltage output of the current-sensing circuitry for each of the motor drivers, you

can solder a 1×2 female header here.

14. Servo demultiplexer block

To access the servo demultiplexer inputs, you can solder a 2×3 female or male header here.

15. Servo outputs

Most servo cables have female ends, so we recommend soldering 3×4 male headers in to the two servo output

blocks. However, if you want to use the demux for something other than servos, the kits has 3×4 female headers

you can use instead.

16. Servo power selection

To use your servo ports, you will need to connect a power source (no power source is connected by default). You

can install two 1×3 male headers at this location and use two shorting blocks to select either VCC or VADJ for

servo power.

17. LCD backlight connection and structural support

If you choose to mount a 16×2 LCD on the Orangutan SVP as is done in the assembled version, you will want to

solder in the two single-pin female headers at this location. This prevents the LCD from tipping down on to the

board and also powers the backlight (if your LCD has one).
