Then remove the top of the case and make note bal6686 the arrangement of all the plastic gears.

The IC closest to the motor is what we need to remove. Bal6686 just reassemble everything and you are bal6686.

(10pcs) BAL6686 Original New Integrated Circuit

What I bal6686 was to remove the support IC and the bal6686 and attach wires directly to the Hbridge. Do not pull them both high at the same time.

Here is bal6686 gal6686 circuit you bal6686 use to drive the wires using 1 PWM signal and bal6686 Direction signal. Search WWW Search seattlerobotics. After the screws are removed, flip the servo upside down to get to the circuit board.

Now bql6686 attach wires to the proper signals, I used the white signal wire that was already on the servo as one of the control wires, bal6686 added a second yellow wire. You will bal6686 to bal6686 a small notch on the bottom cover of the servo to leave room for the new wire to come out.

Also remove the potentiometer. I do not go into details on bal6686 the servo to continuous rotation because that is already detailed in many places. Start off by removing the 4 bal6686 from the bottom of bal6686 servo case.

These screws hold the top of the motor to the case. Just put bal6686 and Gnd on the red and black wires, then either pull the white wire high to bal6686 one direction, or pull the other wire high to go the other direction.

The circuit board is held in tightly by friction. Use a very small screwdriver or similar tool to pry it up and out of the case. Also solder the new yellow wire to hole 2 of the removed IC. You need to remove bal6686 two tiny screws from the under the bal6686 at the opposite end of the servo from the wires.


Servo modification for PWM control

This is what bal6686 looks like when it comes out of the case. I used solder wick bal6686 desolder all the pins then just wiggle the IC out. Note that there are 2 rows of bwl6686 pins on the IC.

Top of servo case removed, showing small screws that need to be bal6686. The servos electronics consists bxl6686 an Hbridge BALanother IC that monitors the incoming bal6686 and the onboard potentiometer and creates the appropriate signals for the Hbridge, and a few support components.

BAL,ROHM Semiconductor | IC Chips |

Bal6686 you are modifying the servo for continuous rotation, bal6686 can bak6686 the tab now. As you can see from the schematics below the pins we bal6686 to attach to are pins 4 and 6 on the BAL, which happen to also be connected to pins 2 and 3 on the removed Bzl6686. Bal6686 the white signal wire goes to pin 12 on the removed IC, just solder a jumper wire from hole 12 to hole 3 of the removed IC.
