I will do esp32, stm32, nrf, or atmel pcb and circuit design

Need a circuit board built around a specific microcontroller? I design schematics and PCBs for ESP32, STM32, nRF52, and Atmel-based projects matched to your exact chip, power requirements, and peripherals.

Whether you're building a BLE wearable on nRF52, an industrial controller on STM32, or a connected device on ESP32, I handle chip-specific design considerations (decoupling, crystal placement, RF layout for wireless chips) that generic PCB templates get wrong.

What you'll get:

• Chip-specific schematic design (power, clock, peripherals)
• PCB layout optimized for your microcontroller family
• BOM with verified part availability
• Gerber, drill files
• Basic design notes on why key decisions were made

Chip families covered:

• ESP32 / ESP32-S3 / ESP32-C3
• STM32 (F0H7 series)
• nRF52 (BLE-focused designs)
• ATmega / Atmel AVR

Before you order: message me with your exact chip part number and required peripherals (sensors, connectivity, power source) chip-specific quirks (like nRF52 RF matching or STM32 clock trees) affect scope and price.
