About this Gig
HELLO AND WELCOME!
Need a battery-powered e-paper device that lasts months on a single charge? I build complete low power boards around ESP32 and STM32, from schematic to working firmware.
My Services:
- Schematic capture and 2 or 4-layer PCB layout
- E-paper / e-ink display integration
- Embedded firmware in C/C++ (ESP-IDF, Arduino, STM32 HAL)
- Deep sleep and power optimization
- WiFi and BLE connectivity
- Gerber, BOM and pick & place files ready for JLCPCB or PCBWay
What Sets Me Apart:
- Hardware and firmware from one engineer, so nothing gets lost between teams
- Sleep current measured on real hardware, not just estimated
- Clean, commented source code you fully own
- Clear progress updates at every stage
Message me before ordering with your display size, battery type and target battery life, and Ill recommend the right package. Lets build something that lasts!
Platform:

FAQ
Do you order the PCB fabrication for me?
I deliver fab-ready Gerber, BOM and pick & place files, so you can order directly from JLCPCB or PCBWay. If you’d like me to place the order and handle assembly, add the “Fab Order Handling” extra.
Which e-paper displays do you support?
Most SPI e-paper panels, including Waveshare, Good Display and similar modules from 1.54" to 7.5", in black/white, 3-color and 4-color. If you already have a panel, send me its model number.
How long will my device run on battery?
That depends on your battery, how often the screen refreshes, and how often it uses WiFi or BLE. Many builds reach several months to over a year. I’ll estimate the battery life for your setup before we start.
