Compact ESP32 Controller
A compact controller board integrating an ESP32-WROOM-32E, coin-cell RTC, piezo buzzer, two buttons and screw-terminal field interfaces.
Status: Built
Embedded Systems & Firmware Development in Malaysia
Coordinate firmware, electronics and interfaces so the embedded system behaves predictably in its actual operating environment.
Problems this service addresses
- A custom controller needs production-oriented embedded firmware
- Hardware and firmware teams are blocked by unclear interfaces
- A proof of concept needs a structured path toward a maintainable prototype
- Communication, sensing or control behaviour is unreliable
Who this service is for
- Machine builders and system integrators
- Connected-product teams
- Industrial equipment companies
- R&D teams needing external embedded support
Possible engineering scope and deliverables
- Firmware requirements and state modelling
- Microcontroller and peripheral strategy
- Driver and interface implementation
- Control, sensing and communication logic
- Diagnostics and fault-handling approach
- Hardware-in-the-loop bring-up support
- Source code and build documentation within the agreed scope
Information needed to begin
- Required behaviours and timing constraints
- Hardware documentation or target board
- Communication protocols and external interfaces
- Known fault cases and acceptance criteria
Engineering process
- Define system states and interfaces
- Establish firmware architecture
- Implement and integrate in increments

Networked Electronics Controller 01R1
An ESP32-based controller platform combining wired Ethernet, USB-C, timekeeping and local controls, represented by two assembled hardware revisions.
Status: Iterated
Important project risks
- Field reliability requires testing in representative operating conditions.
- Third-party libraries and cloud services introduce dependencies that must be assessed.
- Safety-critical or regulated software requires a separately defined assurance process.
Frequently asked questions
Which microcontrollers do you support?
Platform selection is based on the application. Existing work includes ESP32 and STM32-class systems, but the device choice should follow the interfaces, performance, sourcing and lifecycle requirements.
Can you troubleshoot existing firmware?
Yes, when source access, a reproducible failure and suitable hardware access are available. The investigation scope depends on the evidence and test setup.
Can hardware and firmware be developed together?
Yes. Coordinating both disciplines is often the clearest way to control interfaces and reduce integration risk.
