Hi, For a simple sensor node, a 2-layer board is absolutely fine and will keep your fabrication costs at rock bottom. However, doing Wi-Fi on 2 layers in a tight 50x50mm space introduces a specific layout trap that I will solve for you. The 2-Layer RF Ground Trap: When routing I2C and GPIOs to your sensor headers, it is very easy to accidentally slice up the bottom ground plane with signal traces. If the ground plane directly beneath the ESP32 is fragmented, you destroy the RF return path. This causes the Wi-Fi signal to drop out randomly and introduces noise into your ADC readings. I will design this 2-layer board using strict component grouping. I will route your sensor headers and USB-to-UART lines almost entirely on the top layer, guaranteeing the bottom layer remains a solid, unbroken ground plane for maximum Wi-Fi range and stable power delivery.

I can help you create a reliable design, is easy to manufacture and flexible enough for future integrations. For this board, I would focus on a few critical aspects that often determine whether ESP32 designs work flawlessly in production: • Stable power architecture with proper decoupling and filtering to ensure reliable Wi-Fi/BLE operation. • Correct RF layout practices (antenna keep-out, ground strategy, placement) to preserve wireless performance. • A compact 2-layer layout within the 50 × 50 mm target while keeping routing clean and assembly-friendly. • Flexible I²C, ADC, and GPIO headers so environmental sensors (temperature, humidity, motion, etc.) can be added without redesigning the board. • USB-to-UART programming interface and clear bring-up points for easy flashing and debugging. All components will be selected from JLCPCB libraries. Deliverables: • Complete schematic and PCB design • Gerbers and drill files • Pick&Place file and assembly-ready BOM • Basic bring-up guide so you can flash firmware and test Wi-Fi/BLE immediately Iwill be glad to collaborate and help turn this into a robust IoT core board.
