Why controller pricing matters for your project
When you budget a robot, IoT gateway, conveyor or student project, the controller line-item often drives choice: cost affects power stage, I/O count, enclosure and testing. Communica stocks a wide range of motor controllers, MCU development boards and PLC-style controllers so you can choose based on performance, not guesswork. Local availability shortens lead times and keeps prototypes moving to test rigs and classroom labs.
Where our advantage helps your budget
We maintain stock in Samrand (head office) with branches in Pretoria and Cape Town, making branch collection and account invoicing straightforward for education and procurement teams. That means predictable VAT invoices, easy quotations for batch buys, and fewer surprises on delivery compared with importing single units.
Typical price brackets and what they buy you
Below is a practical price/feature breakdown to orient decisions quickly - real ranges reflect common controller lines we stock for makers, students and technicians.
| Controller Type | Typical Price Range (ZAR) | Typical Use | Key Specs |
|---|---|---|---|
| Microcontroller boards (e.g., Arduino, STM32) | R 150 - R 1,500 | Prototyping, education, small automation | MCU, USB, 3.3/5V I/O |
| Single-board computers (e.g., Raspberry Pi) | R 800 - R 6,000 | Edge compute, IoT gateways, vision | CPU, Ethernet/WiFi, HDMI, USB |
| Motor drivers / ESCs (brushed, brushless) | R 120 - R 4,000 | Robotics, drones, conveyor motors | Voltage, continuous/peak current, PWM freq |
| Compact PLC / logic controllers | R 1,200 - R 12,000+ | Industry-lite automation, education labs | I/O count, comms: Modbus/RS485/Ethernet |
Compare specs, not just price
A low price can hide upgrade costs. Check voltage and current headroom, thermal derating, I/O levels and communication compatibility. For motor controllers the three quick checks are: continuous current rating, stall/peak current margin and cooling provisions.
