About this Gig
Are you building a smart device that needs a crisp, low-power E Ink display? You are in the right place.
I specialize in bringing E Ink-based products to life from initial concept to a fully working, production-ready solution. Whether you need a custom PCB, embedded firmware, or a complete hardware system, I deliver clean, efficient, and reliable results.
What you get:
- Schematic capture & PCB layout (KiCad / Altium)
- Gerber files & Bill of Materials (BOM)
- Embedded firmware in C/C++ for microcontrollers
- E Ink driver integration (SPI/I2C protocols)
- Low-power & sleep mode optimization
- IoT & wireless connectivity support (BLE, WiFi)
- DFM (Design for Manufacturability) review
Industries served:
Retail price tags | Medical wearables | Smart home | Asset tracking | Agricultural sensors
Why choose me?
I focus on power efficiency, signal integrity, and clean firmware architecture so your product works reliably in the real world, not just on paper.
Message me before ordering to discuss your project needs.
Let's build something great together!

FAQ
What information do I need to provide before you start?
A brief project overview, your preferred microcontroller or platform, display size/resolution, power requirements, and any reference materials or datasheets you already have.
Which E Ink display brands and controllers do you support?
I work with major brands including Waveshare, Good Display, and Pervasive Displays, supporting controllers like UC8151, SSD1675, and IL0373 via SPI/I2C interfaces.
Can you help if I only have an idea and no technical specs yet?
Absolutely. I can help define your technical requirements, recommend the right components, and create a roadmap from concept to a working prototype.
Will I own the full rights to the schematic, PCB files, and firmware?
Yes. Upon final payment, all source files, including schematics, Gerber files, and firmware source code — are fully transferred to you with complete ownership rights.
