Reliable local supply of controllers for projects and production
Need a controller in-hand this week rather than waiting months? Communica stocks a broad range of microcontrollers, development boards, programmable logic controllers (PLCs) and embedded controllers suitable for hobby projects, tertiary study labs, prototyping and small-scale production runs. Our advantage is practical: fast regional availability, VAT invoices for procurement, and branch collection from Samrand, Pretoria CBD or Cape Town to keep your timeline on track.
What we carry and why it matters
We focus on parts and platforms that solve common maker and engineering problems: development boards that plug into breadboards, small-footprint controllers for enclosed products, and industrial controllers with real-world IO. Popular ranges in stock include microcontroller boards for education and prototyping, compatible accessory shields, and controller-ready sensor packages. These product groups cover classroom labs, robotics builds, IoT gateways and low-volume OEMs.
Quick compatibility guidance - pick the right controller
Match controller capability to application demands: processing, IO count, analog inputs, communication interfaces (UART, I2C, SPI, CAN, Ethernet) and power options. If you’re upgrading a prototype to a product, prioritise controllers with exposed UART/USB bootloaders and stable power domains to simplify production debugging.
- For learning and prototyping: low-cost microcontroller dev boards with USB bootload (Arduino-style, RP2040, ESP32).
- For robotics and motion: controllers with multiple PWM channels and motor-driver compatibility.
- For industrial use: compact PLCs or embedded controllers with relay/transistor outputs and DIN-rail mounting options.
Specification callouts to watch
When comparing controllers, check these specs side-by-side: CPU core and clock, flash/RAM, ADC resolution and channels, native network interfaces, and available development toolchains. Below is a compact comparison table to guide selection.
| Type | Typical CPU | I/O | Best for |
|---|---|---|---|
| Education Dev Board | ARM Cortex-M0/M4, RP2040 | 20-40 GPIO, ADCs | Classroom projects, prototyping |
| WiFi/BLE MCU | Tensilica Xtensa / Xtensa + dual cores | GPIO, ADC, WiFi | IoT sensors, connected devices |
| Compact PLC | ARM Cortex-M / embedded | Digital IO, relay outputs | Machine control, small automation |
