About this Gig
Hello and Welcome!
Custom toy electronics require precise signal handling, reliable motor actuation, and compact circuit integration to deliver consistent, responsive control.
I design custom toy circuit boards, joystick interfaces, servo controllers, and embedded systems for interactive toys, robotic toys, RC devices, DIY mechanisms, and electromechanical prototypes.
What I Will Provide:
- Custom toy PCB design and schematic development
- Joystick input circuits and analog signal processing
- Servo motor control and PWM signal generation
- Microcontroller integration (ESP32, STM32, Arduino)
- DC motor, actuator, and driver circuit integration
- Embedded C/C++ firmware development
- PCB layout, component selection, BOM, and Gerber files
Why Choose Me?
- Engineering focused, application specific circuit design
- Reliable signal processing and responsive actuator control
- Firmware and hardware integration expertise
- Clear communication and structured technical delivery

FAQ
Can you design a complete custom toy circuit board?
Yes. I can design a custom PCB around your microcontroller, joystick, servo or motor interfaces, power supply, and required features.
Can you develop joystick interface firmware?
Yes. I can implement analog joystick reading, ADC processing, input calibration, dead-zone handling, and control mapping according to your requirements.
Can you control multiple servos?
Yes. I can implement PWM-based servo control for multiple channels, subject to the microcontroller's capabilities and the project's timing requirements.
Can you integrate DC motors and other actuators?
Yes. I can integrate suitable motor-driver circuits and develop firmware for DC motors, servos, and supported actuators.
Which microcontrollers do you support?
I can work with STM32, ESP32, Arduino compatible boards, and other suitable microcontrollers, depending on the hardware and firmware requirements.
