I will develop electronic shelf label pcb and firmware with stm32 esp32 microcontroller

A digital shelf label is only as reliable as the circuitry and firmware working behind its screen.

One unstable connection, inefficient power circuit or failed display update can compromise an entire retail labeling system.

I help ESL manufacturers, retail technology companies and IoT developers build dependable electronic shelf label solutions using STM32 and ESP32 microcontrollers, combining PCB engineering with embedded firmware development.

Circuit Architecture:

• PCB Schematics
• Board Routing
• MCU Integration
• Power Circuits

Firmware Intelligence:

• STM32 Programming
• ESP32 Programming
• Display Drivers
• Wireless Communication

Retail Advantages:

• Battery Efficiency
• Faster Updates
• Stable Connectivity
• Display Reliability

Engineering Edge:

• Clean Routing
• Compact Hardware
• Source Delivery
• Hardware Debugging

System Capabilities:

• E-Paper Support
• BLE Connectivity
• SPI Integration
• Low Power

Your ESL system deserves more than a board that simply powers on. It needs hardware and firmware that work together.

Send me your specifications, preferred microcontroller and display module. Let's turn your electronic shelf label concept into a working hardware solution.
