Why choose Communica for development microcontroller boards
Communica keeps useful development hardware within reach - not weeks away. For makers, educators and engineering teams, that means immediate prototyping, classroom continuity and predictable purchasing. We focus on availability, practical compatibility guidance and accessory bundles that reduce integration time and unforeseen delays.
Local stock and collection convenience
Our Samrand warehouse and branches in Pretoria and Cape Town let you check stock and collect the same day where available. For branch details and opening times, see Branches & Trading Hours. Bulk or account purchases include VAT invoicing suitable for education and procurement workflows.
Breadth of boards and brands
We stock development boards ranging from beginner-friendly microcontrollers to advanced ARM Cortex and ESP32 modules. Popular maker and industrial-friendly brands you can compare at our brand page: Shop by Brand. Typical ranges include Arduino-compatible boards, Raspberry Pi HATs and standalone microcontroller modules for robotics and IoT prototypes.
Specification callouts you should check
When selecting a dev board, confirm these practical specs - CPU architecture, operating voltage, available I/O, built-in peripherals (WiFi, BLE, ADC), and bootloader/programming interface. Below is a concise comparison table to help speed decisions.
| Board | Core | Voltage | Key I/O |
|---|---|---|---|
| Arduino Uno (compatible) | AVR (ATmega328) | 5V | 14 digital, 6 analog |
| ESP32 Dev | Dual-core Xtensa | 3.3V | WiFi, BLE, ADC, multiple GPIO |
| STM32 Nucleo | ARM Cortex-M | 3.3V | High-speed ADC, timers, SWD |
Compatibility guidance and accessory bundles
Pair your board with level-shifting, a suitable power supply and connectors to avoid midday project stalls. We offer curated starter bundles and sensor kits that group a board, power module, prototyping shield and common sensors to get classroom groups or project teams productive in one order.
