German Leopard 2 Tanks - TK22A

Features

• Uses 4-CH conventional PWM or 10-CH  S.BUS  RC system to control R/C tank's forward/backward movement, sharp turning, pivoting, turret rotation and gun barrel evaluation at variable speed
• Ultrasonic ESC*3  for two track motor and turret rotation
• Carefree reversing
• Ultra Low turn-on resistance FET for track motor ESC
• 22KHz, 8-bit high quality sound with digital sound mixer
• Maximum of 5 channel of sound track, main gun, machine gun, turret rotate, gun barrel elevation and engine sound can be generated at the same time
• 3W sound output power
• 0.8A BEC
• EPM*2 for gun elevation(EPM1) and turret rotation/gun traverses(EPM2) 
• Wide operating voltage rage, from 7.2 to 12V, support  3S Li-Po battery
• Support air-soft gun with sound synchronization
• Support TAMIYA and HL IR battle unit and format
• Support RealRecoil servo port
• Safety shutoff prevents unwanted movement while signal lost
• Auto R/C signal detection
• Miniature design(60mm X 50mm X 20mm) for 1/25~1/16  R/C Tank
• V1 Engine Sound Simulation

Terminology

• Ultrasonic ESC is the ESC block which switch FET at ultrasonic speed, allowing motor rotation to be extremely  smooth and quite. Start voltage of ESC can also be adjusted for different type of motor.
• Carefree reversing: 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),
