Firmware & bare-metal
C and C++ against the datasheet: peripheral drivers, DMA paths, interrupt latency budgets, secure bootloaders and low-power state machines that survive a real duty cycle.
Synapses Technologies LLC
We make embedded
things think.
Firmware, PCB, RTOS, robotics and connected fleets, engineered as one nervous system rather than a stack of parts.
01 / Capabilities
The whole signal path,
owned end to end.
Most embedded products fail at the seams: between board and driver, driver and scheduler, device and cloud. We work across all of them, so the seams are ours to answer for.
PCB design & bring-up
Part selection, schematic, multilayer layout, power integrity and EMC-aware routing, then the unglamorous part: rails, clocks, JTAG and a board that boots.
RTOS & real-time
Zephyr and FreeRTOS integration done deliberately: task decomposition, priority and locking discipline, deterministic control loops, and jitter measured rather than assumed.
Connectivity & IoT
BLE, Wi-Fi, LTE-M and LoRa stacks with a provisioning story, signed OTA, and telemetry that stays intelligible once there are ten thousand devices instead of one.
Robotics & motion
Motor control, sensor fusion, kinematics and ROS 2 bridges, from the current loop up to the behaviour a machine is actually judged on.
Automotive & industrial
CAN and CAN-FD networks, UDS diagnostics, Modbus and industrial buses, plus the traceability and process discipline regulated programmes expect.
02 / Signal path
Every node is somebody's integration problem. A sensor reading becomes an interrupt, a task, a bus frame, a packet, a row in a dashboard. We design that path once, instrument it, and keep the latency and failure behaviour of each hop written down.
Board
Schematic capture, layout, DFM review, first power-on and bring-up.
Firmware
Drivers, bootloaders, power management and the timing budget that holds them.
Real-time
RTOS tasks, schedulability, control loops and embedded Linux where it earns its place.
Fleet
Provisioning, OTA, telemetry pipelines and the app or dashboard on the far end.
03 / How we work
Four phases, each ending
in something you can test.
Scope & architecture
Requirements, part shortlist, block diagram and a written timing and power budget. Ends in a spec you could hand to anyone.
Prototype
Dev-kit or first-spin board with the risky subsystem proven first. Ends in a demonstrable device, not a slide.
Harden
Unit and hardware-in-the-loop tests, fault injection, EMC and thermal reality, CI on real targets. Ends in measured numbers.
Ship & sustain
Production programming, signed OTA, telemetry and a handover your own team can carry. Ends with you not needing us.
04 / Platforms
Tools we already know
If your stack isn't here, it is usually a week of ramp, not a reason to change it.
