Embedded Systems & Custom Hardware

Hardware development leaves no room for error. A bug in code running on a remote microchip cannot be fixed with a quick hotfix if the unit loses power or connectivity. We treat hardware and firmware engineering with the mathematical rigor required to guarantee long-term stability in the field.

Hardware-Software Co-Design

We own the entire hardware loop. By designing both the schematic/layout and writing the low-level firmware, we optimize for component availability, power consumption, and mechanical constraints.

• Custom PCB Layout: We design multi-layer, noise-isolated printed circuit boards (PCBs) using industry-standard tools. We pay close attention to EMI/EMC compliance, impedance matching for high-speed signals, thermal dissipation, and robust power delivery networks (PDNs).
• Low-Power Firmware: We write bare-metal C/C++ or FreeRTOS code for microcontrollers (ESP32, STM32, Nordic nRF). We optimize firmware for ultra-low power consumption by utilizing deep sleep modes, hardware interrupts, and DMA-driven peripheral transfers.
• Resilient Ingest Protocols: Cellular and satellite networks are expensive and unreliable. We design compact, binary telemetry formats (such as Protobuf, CBOR, or bit-packed custom structs) to minimize data payloads. Our firmware implements store-and-forward buffers so data is never lost during connectivity drops.

Safe Updates (OTA)

We implement robust Over-the-Air (OTA) firmware update loops with hardware-level fallbacks:
