STM32 Jobs

I need a complete 6LoWPAN implementation running on an STM32 based node that will be used in automated control systems. The radio transceiver module already embeds the IEEE 802.15.4 PHY and MAC, so your work starts at the adaptation layer upward: building, porting, or custom-writing the 6LoWPAN stack, exposing an easy-to-use API for my application code, and demonstrating reliable mesh communication between multiple nodes in the field. Hardware • Microcontroller: I can work with any Cortex-M0/M1/M2/M3/M4 device, so feel free to target the STM32F0, F4, L4, or whichever family you find most power- and memory-efficient for the stack. • Radio: external module with integrated PHY/MAC; SPI or UART host interface is available and fully documented. Scope of work 1. Port ...

My current board is built around an STM32F429VIT6 and two legacy light-measuring devices that have just gone end-of-life. I have sourced drop-in phototransistors with the same pinout and essentially the same electrical characteristics, so the hardware change should be straightforward: swap the parts, adjust the footprints if necessary, and regenerate the fabrication files. What I need from you: • Update the schematic and PCB (the original files are in Altium Designer; if you prefer KiCad I’m happy to migrate). • Produce new Gerbers, pick-and-place, updated BOM and a brief change log. • Review the analogue front-end around the sensors to be sure biasing and filtering remain optimal for the phototransistors. On the firmware side, the project is written in C ...

I have a CAN-based hardware concept for trucks and excavators that still needs an expert eye and solid firmware. The board carries a CAN transceiver plus an as-yet-undecided microcontroller; your first job will be to review the schematic and component choices, making sure the design can reliably tap into a heavy-vehicle J1939 network. Once the electronics check out, I need production-ready code that listens for multiple PGNs, performs light, on-board processing, and then forwards all remaining data to my back-end through a Bluetooth link. On the edge we have to handle three record types: sensor readings, diagnostic trouble codes, and operational parameters. Any PGN we do not actively process must be packed efficiently and shipped over Bluetooth for cloud processing, so memory management a...

I already have a complete schematic for a multi-function meter built around the STM32H743BIT6. Before I move to PCB layout I need a fresh set of eyes to refine the design, swap a few key parts, and fold in two new capabilities. Work required • Correct any schematic errors you spot (net ties, pin assignments, power flags, ERC issues). • Replace the specified parts—new values for several resistors and capacitors plus an updated pin-compatible MCU revision. • Add extra sensing channels and tighten the power-management section so the board runs cooler and meets my standby-current target. • Schematic circuit diagram design and PCB Design in Altium software. We may provide Altium software. • Simulation required in Proteus software. We may provide software. &...

I’m building a consumer-grade entertainment device whose flagship feature is smooth, responsive gaming support. I need an embedded systems engineer who can take the idea from concept to working prototype, covering hardware selection, board design, firmware, and performance tuning so the final unit feels console-class in a much smaller, cost-effective form factor. Core requirements • Craft the hardware architecture around an SoC or high-performance MCU that delivers reliable gaming performance without exceeding a 5 W power envelope. • Produce schematics, BOM, and a production-ready multi-layer PCB. • Write and optimise the firmware or RTOS layer that boots quickly, handles user input, and drives audio/video output at 60 fps or better. • Build in easy hooks...
