Hardware and firmware for devices that have to live on site

When the device in the wall needs to debounce a loop, cache credentials or speak a protocol nothing off the shelf supports, we design the board and write the firmware.

IoT sensors and controllers that report in, update securely and fail safely. Embedded work for gate and door controllers, reader interfaces and protocol bridges between legacy equipment and modern software.

We design for timing, electrical noise, brownouts and the fact that someone will eventually wire it wrong. Firmware fails in a way a facilities team can describe over the phone.

What our hardware development service covers

Requirements and hardware architecture
IoT sensors, controllers and gateways
Custom PCB design and prototyping
Firmware for microcontrollers and embedded Linux
Protocols: RS-485, Modbus, Wiegand, CAN, MQTT
Testing, small-run production and documentation

Products in this service

IoT devices

Equipment health, utility metering, environmental sensing and controllers that bridge legacy site systems to modern dashboards. Devices report in and take secure updates.

Embedded firmware and boards

Timing, I/O and the protocols real gates and readers speak. Firmware that debounces, caches and fails safely — hardware designed for small to medium production runs.

Why choose Bayam for hardware development

Field context from the gates, networks and readers we also install
Firmware written to fail safely and report in plain language
Prototyping through to small-run production

Frequently asked questions

Do you manufacture?

We handle prototyping and small to medium runs through partner facilities.

Can you replace a discontinued controller?

Often yes. We reverse-engineer the interface and build a compatible replacement.

Cloud or on-premise for IoT?

Either. Many site systems are better kept local, with cloud used only for remote access and reporting.

How do we start?

Tell us the protocol, the enclosure constraints and what the device must still do after a power cut.
