World's First integrated RC tank controller with Carefree reversing Ultrasonic ESC
THIS IS NOT 100% PLUG AND PLAY BOARD, SIMPLE CHANGE IS NEEDED FOR FULL OPTIONS
(specifications and design are subject to change without notice)
Ultrasonic ESC is the ESC block which switch FET at ultrasonic speed, make motor rotation extreme smooth and quite. start voltage of ESC can also be adjusted for different type of motor.
Unlike some other control board, there is no need
for TK series board to
delay before being commanded to reverse,
can go from full forward immediately to full reverse or vice versa
EPM ( ESC/PWM module) is peripheral which can be switched to ESC or PWM mode, allows the user to drive brushed motor or servo motor, in ESC mode, ESC port is enabled, can be used to drive brushed motor, In PWM mode, PWM port is enabled to driver servo motor, sound effect stopped when servo motor reach end point, TK20A has 2 EPMs for gun elevation(EPM1) and turret rotation/gun traverses(EPM2),
RealRecoil allows you to recreate real gun barrel recoil movement with single & cheap servo motor
Recoil Solenoid allows you to recreate MG/Auto cannon barrel recoil movement with Solenoid
V2 Mixer turning is achieved by reducing track speed and also increase opposite track speed to achieve smoother turning.
* 20A if to connect motor from on-board connector, 60A if hardwire motor to PCB pads

Connector and pin assignments
Set Upper Hull Functions (CN9) Mode to match your tank hardware configuration (HL AirSoft, TAMIYA Recoil or MG recoil),
Disconnect RX-18 and plug cables to the same connector on TK board,
Set Sound Volume to middle
Install a switch cable (for example, HL Smoke Unit Switch Cable) to SW connector( Switch Cable Port) as power switch.
Because HL tank already have power switch on battery cable path, so additional switch is not required, just to use a jumper to short pins in SW Cable port or connect a switch cable and keep it switched on.
When high current track motors are used, such as 400/480 motor, power switch on battery cable path will not be able to handle, connect a switch cable (for example, HL Smoke Unit Switch Cable) to this port as power switch.
Connect a recoil servo to J2(Optional),
Rewire Air-soft unit if you want to elevate and depress gun directly, see "HL Gun Elevation and AirSoft Correction" section
(Optinal). wire a 2.2 ohm 1/2W (color code: red read gold gold) in-serial resistor to turret rotate, elevation and airsoft motor to limit the current to protect FETs in case motor stall occured.
Connect channel cables to receiver according to RC mode( See picture "TK series connector and pin assignments" ) . if you are not sure what mode you RC system is, just swap CH2 and CH3 and try again.
TK20A board has BEC( Battery eliminate circuit), can power receiver through channel cables, no additional battery is needed for receiver

Status read out and IR battle test by IR configuration remote
Point Configuration IR remote to TBU/HBU and press key listed below to show vehicle status or test IR battle function. No jumper should be installed on J1.
Q: My TK board can not register a hit from Tamiya tank.
A: To check "Receive Tamiya IR code" setting. TK board won't response Tamiay IR code when this setting is disabled.
The airsoft motor does not run until after the gun fire sound has played and the
reload sound has happened. I want the airsoft motor to run while the gun sound
plays. I also planned to make recoil work with the airsoft…but when I fire the
gun, the recoil servo operates in time to the sound…but has returned to the
normal position when the airsoft motor operates.
Q: I already set Main Gun Function Mode to HL AirSoft MODE, but AirSoft motor does not run when I give fire cannon command.
A:To correct airsoft unit wiring as HL Gun Elevation and AirSoft Correction section mentioned.
Q: Airsoft unit fires continuously and have no cannon sound.
A: When main Main Gun Function Mode is configured to AirSoft Mode, TK board start to drive AirSoft motor (thought CN9 3rd &4th pin) when fire cannon command is received. when Airsoft just fired, Airsoft switch is closed , TK board knows it thought CN3 Pin4 & Pin5. and then stop to drive Airsoft Motor and start to generate cannon. So in order to make it works properly, AirSoft motor need to be connected to CN9 pin3 and pin4. AirSoft switch connector to CN3 Pin4 & Pin5.
You can simply test it by a tweezers, to short and release it will stop AirSoft motor.
How to avoid damage that caused by short circuit to the board?
then connect + wire(with white strip) from adaptor to red wire of HL cable, - wire to black wire of HL cable, adn wire resistor and LED as the following to act as indicator.
Each time, when you did some modification on circuit or after installation, use this as power source fist. plug connect each by each, and LED will be dimmed immediately if any shortage in circuitry and not thing on TK board will be damaged because power can only supply low & limited current.
The board might be act very strange when it's power by this, such as motor can not moves will, cannon fired unexpectedly when turret rotation sound comes up, these are quite normal because current is not enough.
How to interface TK board to 6W external
First to disconnect black wire from HL Volume control board and isolate it with tape, wire a 2-P, 2.54mm pitch connector wire to Volume control board as shown below
Then to power amplifier by battery
Finally, connect power form TK board to Battery+ & Battery - pin, connect 2-P, 2.54mm pitch connector wire SIG+ and SIG-,and then connect sparker to SPK+ and SPK- pin.
Here is pin assignment of another type 6W AMP, just refer to the above and wire pins with same pin assignment.
Generally, higher the input power, higher the sound output power on speaker, so we can also use a DC-to-DC voltage booster to convert battery voltage into higher voltage, then to drive external audio amplifier to have more solid and powerful sound,
Because output ripple is much lower after DC-to-DC conversion, so this can also reduce motor "humm" sound during motor start up and at low speed. another benefit of this configuration is that you can use 8-ohm speaker but still have good loudness. In the example below, we use an adjustable DC-to-DC voltage booster to convert battery voltage into 12V.
Step 1: first to connect AMP to TK board and battery as describe previous and make sure it sounds correctly,
Step 2: connect
DC-to-DC voltage booster to
battery only, measure the output voltage,
if voltage is higher or less than
12V, adjust VR on it till output voltage is around 12V,
HINT: use VR pointed by black arrow in this diagram to adjust voltage to 12V before powering amplifier
Wiring diagramfor 15W amplifier: Use VR on DC/DC converter to set output voltage to 15V
When I move left stick backward, only the right track goes backward the left
track does not move, It is possible I crossed the +positive and --negative
terminals when connecting the new motors?
We recommend that to use power adapter(7.2V, 400mAh) as power source after rewiring. then switch to battery when everything are tested OK.
Q: Tank hull
recoil movement direction is not correct, moves forward and then backward while
firing main gun.
Q: All function runs but just no sound!!
A: This can be the common issue on HL Volume Control board, just to short outer pins of CN4 with tweezers to verify it. if sound comes out when doing this, the HL volume control board is broken.
Q: Do I need noise filtering capacitor on motor
A: Yes, it's needed to prevent back EMF to interference TK20 board. All HL stock tank already have it on motors
This type of capacitor is not good, DO NOT USE!
Q: What's the IR battle range of TK20
The table below shows the test result we've done here or from customer site,
Q:Tank moves backward faster than forwards and does not turn. It only turn if firstly turn steering stick and secondly throttle stick.
A: To turn off mixer on transmitter and test again.
Q: Can get motor sounds, cannon sounds, turret sounds, but no motion on either drive motors or turret rotation gearbox
A: Check if battery voltage is too low, auto cutoff function cuts motor off when battery voltage is too low.
Q: What is Mixer
A: A piece of software
Rudder and control
Q: What is Safety shutoff:
A: Controller cuts motor off and waits signal come back.
Q: What is Auto cutoff:
A: The motor cutoff will occurred when battery input drops below minimum supply voltage of controller.
Q: Which RC system can works with TK board:
A: Basically, TK can work with all kind of aftermarket RC system as long as it's PWM system, here is a table list most popular one.
Q: Audio Amp thermal protection:
A: that turns off device when junction temperature over 150 degree C to prevent damage
Q: Is it possible to make additional settings using existing IR signals for example to make HL IR signal and 9 hits can take, originally 5 hits?
A: yes, IR code to receive, IR code to transmit, preset & battle data can be set independently.
Q: Is it possible to set setting with other device (not SONY IR code remote)?
A: Only Sony IR code remote can be used, you can also have universal remote and configure it to SONY mode.
Q: Any Other
SONY remote, such as SONY Bravia unified IR
Configuration Remote, can config TK20?
Q: What's BEC
A: BEC stands for battery elimination circuit. This circuit powers the receiver thought channel cable, no secondary battery source is required.
Use dry battery or power supply as power source at testing to keep burn down anything if any error on modification. then use chargeable battery when every function working normally.
Read carefully and fully understand the instructions before commencing assembly.
