Embedded firmware, PCB design and IoT product development
We help companies turn connected product ideas into reliable hardware, production-ready firmware and manufacturable PCB designs.
A Blue Thing In The Cloud is an electronics engineering company based in Valencia, Spain, focused on embedded firmware development, PCB design, IoT connectivity and turnkey electronic product development.
We work with companies that need reliable engineering support for connected devices, wireless products, industrial electronics, low-power systems, sensor nodes, BLE devices, Wi-Fi devices, UWB products and custom embedded systems.
Our core expertise includes:
- Embedded firmware development in C and C++.
- PCB design for real, manufacturable electronic products.
- IoT device development from concept to production.
- Bluetooth Low Energy, Wi-Fi, Thread, Matter, MQTT, TCP/UDP, UWB and custom wireless protocols.
- Nordic Semiconductor, STMicroelectronics, STM32, STM32WB, nRF52, nRF53, nRF70 / nRF7002, Zephyr RTOS, FreeRTOS and bare-metal firmware.
- Hardware and firmware architecture for prototypes, MVPs and production-ready devices.
When technology becomes art.
