Why choose a local controllers stockist
Finding the right controller is about matching function, footprint and supply reliability - not just price. Communica gives South African makers, students and engineers immediate access to PCB-level microcontroller boards, motor drivers, soft starters, and compact PLC-style controllers from stocked ranges. That local availability reduces project delays, lets you collect from our Samrand warehouse or Pretoria and Cape Town branches, and ensures you receive VAT invoices for procurement and tertiary purchase records.
Range highlights and stock practicality
We stock single-board controllers and development kits suited for IoT and robotics, plus motor controllers and power-stage modules for automation and motion projects. Popular maker and industry-compatible brands carried include maker favourites and industrial component manufacturers; check our broader collections to compare categories and brands.
- Development boards: microcontroller and SBC kits for prototyping and teaching.
- Motor controllers: brushed, brushless (BLDC), stepper drivers and H-bridge modules.
- Automation controllers: compact PLC-like units and relay/IO modules for control panels.
Where to check stock and collect
Confirm live stock before you travel: use our samrand head office warehouse for bulk orders or branch collection at the Pretoria and Cape Town locations. For branch details and opening hours visit Branches & Trading Hours and reserve items for pickup.
Controller specifications to compare
Before you buy, compare the electrical and interface specs that determine how a controller fits your project: supply voltage, I/O voltage and count, control interface (PWM, UART, I2C, SPI, CAN), motor current capability, isolation and mounting options.
| Controller Type | Typical Supply | Key Interfaces | Use Case |
|---|---|---|---|
| Microcontroller dev board | 3.3-5V | GPIO, I2C, SPI, UART | Prototyping sensors & IoT |
| Stepper driver | 12-48V | PWM/Step-Dir | Precision motion systems |
| BLDC motor controller | 12-60V | CAN / PWM | Robotics & vehicles |
| Compact PLC-style unit | 12-24VDC / 230VAC | Digital I/O, Modbus | Small automation |
Specification callouts and compatibility guidance
Match the controller's voltage and current ratings to your load, and confirm control signal levels. For microcontroller boards look for 3.3V versus 5V I/O to avoid level-shifting mistakes. For motor controllers check continuous current rating, peak current handling, and recommended heatsinking in datasheets. If you need a quick cross-check of product categories, browse our Collections.
Accessory bundles that save time
Most projects benefit from pairing controllers with nearby-needed items: power supplies sized to the controller and load, motor feedback sensors (encoders or hall sensors), terminal blocks and screw connectors, and protection devices such as fuses or slow-blow holders. Communica groups compatible accessories in product pages for convenient shopping - see our full controllers in stock for specifics.
