Deep-tech embedded engineering across the entire hardware stack. From bare-metal MCU firmware to multi-layer high-speed PCB layout.
From conceptual schematic capture to complex multi-layer high-speed PCB layouts. We handle impedance control, DDR memory routing, RF circuit matching, and rigorous EMI/EMC compliance optimization.
We write highly optimized, low-power C/C++ code for bare-metal MCUs (ARM Cortex-M, ESP32, STM32, Nordic nRF). Expertise in hardware abstraction layers and custom driver development for obscure sensors.
Implementation of deterministic, multithreaded systems using FreeRTOS, Zephyr, or ThreadX. We expertly manage race conditions, thread prioritization, and strict latency requirements.
Custom Yocto or Buildroot Linux distributions for high-performance SoCs (NXP i.MX, Rockchip, Broadcom). We develop custom kernel drivers, device trees, and robust OTA update mechanisms.
Seamless integration of BLE, Wi-Fi 6, LoRaWAN, Zigbee, and Cellular (LTE-M/NB-IoT). We implement secure edge-to-cloud protocols (MQTT, CoAP) with deep hardware cryptographic acceleration.
Bridging the prototype "valley of death". We review BOMs for supply chain resilience, design comprehensive automated testing jigs (PCBA functional testing), and oversee pilot production runs in Shenzhen.
