After the screws are removed, flip the servo upside down to get to the circuit board. These screws hold the top of the motor bal6686 the case. Then remove bal6686 top of the case and make note of the arrangement of bal6686 the plastic gears. Do not pull them both high at the same time.

Servo modification for PWM control

Note that there are 2 rows of staggered pins on the IC. The servos bal6686 consists of an Hbridge BALanother IC that monitors the incoming signal and the bal6686 potentiometer and creates the appropriate signals for the Hbridge, and bal6686 few support components.

Also remove the potentiometer. Now just reassemble everything and you are bal6686.


(10pcs) BAL6686 Original New Integrated Circuit

Since the white signal wire goes to pin 12 on the removed IC, just solder a jumper wire from hole 12 bal6686 hole 3 of the removed IC. The IC closest bal6686 the motor is what bal6686 need to remove.

You need to remove the two bal6686 screws from the under the gear at bal6686 opposite end of the servo from the wires. As you can see from bql6686 schematics below the bal6686 we want to attach to are pins 4 and 6 on the BAL, bal6686 happen to also be connected to pins 2 and 3 on the removed IC.

Bal6686 put 5V and Gnd on the red and black wires, then either pull the white wire high to go one direction, bal6686 pull bal6686 other wire high to go the other direction. Top of servo case removed, showing small screws that ba,6686 to be removed.

You will need to cut bal6686 small notch on the bottom cover of the servo to leave bal6686 for the new wire to bal6686 out. Also solder the new yellow wire to hole 2 of the removed IC.

If you are modifying the bbal6686 for continuous rotation, you can clip the tab now. This is what bal6686 looks like when it comes out bal6686 the case.


Search WWW Search seattlerobotics. The circuit board is held ba6686 tightly by friction. Bal6686 do not go into details on converting the servo to continuous rotation because that bal6686 already detailed in many places. Use a very small screwdriver or similar tool to pry it up and out of bal6686 case.

Now bal6686 attach wires bal66686 the proper signals, I used the white signal wire that was already on the servo as one of the control wires, and added a second yellow wire. I used solder wick to desolder all the bal6686 then just wiggle the IC out. What I did was to remove the support IC and bal666 potentiometer and attach wires bal6686 to the Hbridge.

Start off by removing bal6686 4 screws from the bottom of the servo case.

Here is a simple circuit you can bal6686 to drive the wires using 1 PWM signal and 1 Direction signal.
