Automotive Boards for Sale | Leading South African Supplier - Communica

Comprehensive Range of Automotive Boards in South Africa

Automotive electronics are reshaping modern vehicles, from advanced engine management units to diagnostic CAN modules and development platforms for custom telematics. Whether you're retrofitting a bakkie fleet, developing a student competition project, or supporting independent workshops, sourcing reliable automotive boards locally in South Africa is critical. Communica stocks one of the country's broadest selections of automotive-grade PCBs: ECUs, custom relay boards, CAN bus controllers, power distribution, dashboard driver ICs, and reference-quality embedded development boards.

With over four decades of supplying engineers, technical colleges, and workshops, Communica bridges the gap between global innovation and South African automotive realities—from lead time-prone special imports to quick-turnover stock for teaching, fleet repairs, or rapid prototyping. Our core range includes:

• Circuit boards for CAN bus and LIN-based vehicle diagnostics
• Embedded microcontroller and single-board computers (SBCs) designed for automotive interface
• Relay, power distribution, and high-current switching PCBs for 12V/24V systems
• Sensor boards (temperature, position, pressure) compatible with industry standards
• Open-source vehicular development kits (e.g., Arduino, Raspberry Pi, STM32 with automotive shields)

Leading brands available from stock or on request include NXP, STMicroelectronics, Texas Instruments, Adafruit, DFRobot, and specialist automotive platforms. Both off-the-shelf and prototyping boards are carried, along with accessories such as relay modules, fused enclosures, OBD-II adapters, and connector kits.

Product Types & Key Features

Selection Criteria: Choosing the Right Automotive Board

When selecting automotive boards for local workshops, vehicles, or higher-ed research, consider the following:

• Voltage Compatibility: 12V (standard vehicles), 24V (trucks/heavy-duty), or dual-rail options. Confirm via technical datasheets.
• I/O & Protocols: CAN, LIN, UART, I²C, SPI and compatibility with your diagnostic tools or MCUs.
• Environmental Durability: Boards not housed inside ECUs will need extended temp or vibration tolerance. Refer to specs for maximum ratings.
• Current Handling: For relay and load driver boards, match max current and inrush figures to your application. E.g., Window actuators may spike above 10A briefly.
• Integration Ease: Consider modules with labelled terminal headers, screw connections, or snap-in automotive connectors for fast install and troubleshooting.
• Documentation & Education: Prefer platforms with strong datasheet support, code libraries, and forum activity, especially for university or FET use.

Example Application: CAN Bus Data Logger

A South African fleet manager integrates a CAN-based logger to monitor fuel usage and driver patterns. By selecting a TJA1050-based CAN module (12V input, screw terminals, DB9 output) and pairing with an ARM Cortex board, rapid prototyping and field deployment is achieved-all with parts available for urgent pickup at Communica's Samrand branch. For student projects, Arduino-compatible CAN shields paired with open-source firmware simplify competition entries.

Local Availability, Lead Times & Branch Pickup

Branch pickup (Samrand, Pretoria CBD, Cape Town) allows workshops and students to reduce shipping delays and confirm compatibility directly at counter. All sales are VAT-invoiced and supported by technical queries for integration and troubleshooting. Tertiary institutions may request official quotes or bulk orders via procurement channels.
