PCB DESIGN (KiCad, Altium, EasyEDA) • Schematic capture and multi-layer layout, up to 6 layers • High-speed and RF layout for Wi-Fi, BLE, LTE and GNSS • Power electronics: buck-boost regulators, battery management • Production files: Gerber, BOM, CPL (pick-and-place), assembly drawings • Design review and repair of boards that don't work EMBEDDED FIRMWARE (C/C++) • ESP32 (ESP-IDF), STM32, Arduino, bare metal and FreeRTOS • I2C, SPI, UART, CAN, USB, Wi-Fi, BLE, LoRa • Sensor integration, low-power design, motor control • Debugging with JTAG/SWD, oscilloscope and logic analyzer ROBOTICS • ROS/ROS2 navigation and SLAM (Gmapping, Hector SLAM, RTAB-Map) • Robot simulation in Gazebo and visualization in RViz WHAT YOU GET • Clear scope and milestones before work starts • Regular progress updates with photos or screenshots • Complete, documented source files at the end • Based in Bangkok (GMT+7) Send your requirements, a sketch or an existing design you want to improve, and get back questions and a proposed approach.
