What is your current level of experience in freelance work?
We’re looking for an experienced Electronic Engineer to review a custom PCB design for a low-power sensor module. The board includes a microcontroller (ESP32), a temperature/humidity sensor, Li-ion battery charging circuitry (TP4056), and USB connectivity. The design was created in KiCad, and we’re looking for a second set of expert eyes before proceeding to prototyping. Your role will be to review the schematic and layout, flag potential electrical or design issues, and suggest improvements related to performance, reliability, and manufacturability.
