About this Gig
I will design a custom quadrature encoder interface PCB for motor control, robotics, CNC machines, servo systems, and industrial automation.
What I can design:
- Quadrature encoder A/B channel interfaces
- Optional Z index pulse input
- Single-ended TTL and compatible differential encoder inputs
- RS-422 differential receiver interfaces where required
- Signal conditioning, filtering, and input protection
- Encoder interfaces for STM32, ESP32, and other MCUs
- Timer and hardware encoder-mode interfaces
- Logic-level conversion and connector integration
- Industrial noise immunity and isolation options
- Circuit schematics, custom PCB layouts, and manufacturing files
What you will receive:
- Circuit schematic according to your package
- Custom PCB layout
- Bill of materials (BOM)
- Gerber and drill files
- Editable design files according to your package
I consider encoder output type, supply voltage, signal frequency, cable length, noise environment, and controller compatibility when developing the design.
Please message me before placing an order so we can confirm your requirements and project scope.
FAQ
Can you design an A/B quadrature encoder interface?
Yes. I can design circuitry for reading A/B phase signals to support position, speed, and direction feedback.
Can you include the Z index channel?
Yes. An optional Z channel can be included when your encoder provides an index pulse and your application needs it.
Do you support differential encoders?
Yes. I can design interfaces using suitable differential receivers, including RS-422-compatible receivers, when the encoder output matches their electrical specifications.
Can the PCB connect to an STM32 or ESP32?
Yes. I can design compatible logic-level interfaces and connections for suitable MCU timer, counter, or encoder peripherals.
Can you design for high-speed motor feedback?
Yes. The architecture can be selected according to maximum edge rate, encoder resolution, motor speed, cable conditions, and controller capabilities.
Can you include isolation and noise protection?
Yes. Suitable input protection, filtering, differential signaling, and isolation can be considered according to your operating environment.
Do you provide motor-control firmware?
Firmware and motor tuning are not automatically included. They can be discussed separately from the encoder interface hardware design.
