Product range and clear compatibility guidance

We focus on real-world compatibility: choose controllers designed for your motor type, control interface and supply voltage. Popular boards and modules we carry include microcontroller development boards, Raspberry Pi and Arduino adapters, stepper and DC motor drivers, and integrated motion controllers for ROS and embedded systems.

Quick selection checklist

• Motor type: stepper, brushed DC, brushless DC (BLDC) - match driver topology.
• Voltage/current ratings: choose controllers rated above peak motor current.
• Control interface: PWM, UART, SPI, I2C, Step/Dir, CAN or Ethernet.
• Features: microstepping, regen braking, encoder feedback, closed-loop support.

Specification callouts and compatibility tips

When comparing models, check continuous and peak current, operating voltage and required heatsinking. For teams using Raspberry Pi or microcontrollers, confirm logic-level compatibility (3.3V vs 5V) and whether a level shifter or driver board is needed.

Simple current and power check

Use Ohm’s law and power basics when sizing supplies and controllers. Example formula:

V = I × R ; P = V × I

If a motor draws 10A peak at 24V, peak power = 24 × 10 = 240W. Specify a controller and supply rated above that peak and allow headroom for safety and thermal dissipation.

Local availability and collection options

Avoid overseas delays: check real-time stock and reserve items for pickup at Samrand, Pretoria or Cape Town. See branch locations and hours: robot controllers in stock.

Bundles, accessories and integration guidance

We pair controllers with the right accessories so your prototype works first time: motor cable assemblies, encoder modules, heatsinks, current-sensing shunts and compatible power supplies. Popular bundles combine a controller, power module and encoder breakout tailored for student labs and small-scale production runs.

Wiring diagram (example: stepper driver to MCU)

Simple wiring ASCII diagram for Step/Dir connection:

MCU     ->  Driver
GPIO_STEP -> STEP
GPIO_DIR  -> DIR
GND       -> GND
+3.3V/5V  -> VLOGIC (check driver voltage)

Ensure common ground and confirm logic levels before powering motors. For encoder feedback, route A/B channels to interrupt-capable pins on your MCU.

Troubleshooting tips

• Motor stalls: increase current limit slightly and check microstepping settings.
• Overheating controllers: add heatsinks or improve airflow; check peak vs continuous ratings.
• Communication failures: verify baud rates, check level shifting and grounding.

Procurement, education and bulk quoting

For classrooms, labs and production runs we provide VAT invoices, account quoting and reserve-for-collection options. Our Samrand warehouse keeps larger quantities for faster delivery across South Africa. For company or tertiary orders, request a quote via our About Us page to discuss lead times and staged deliveries: About Communica.

Objection handling and why local matters

Concerned about stock continuity or compatibility? We publish live stock levels and can source alternatives from thousands of brands when a specific SKU is delayed. Local pickup removes customs delays and simplifies VAT documentation for institutions and businesses. Need help choosing? Our branches in Pretoria and Cape Town offer technical advice and hands-on support-check branch hours: Branches & Trading Hours.
