Find the right development microcontroller board in South Africa
If you need a development board today - for a class, a prototype sprint, or production validation - Communica stocks a broad range of microcontroller boards from entry-level Arduinos to advanced ESP32 and RP2040 modules. We prioritise availability and practical support: check stock locally, collect from Samrand or our branches in Pretoria and Cape Town, and obtain VAT invoices for procurement or tertiary reimbursements.
Why buy locally from Communica
Local stock reduces lead time risk and lets you iterate faster. Communica offers same-region pickup, account quoting for procurement teams, and accessory bundles that get projects working out of the box.

Quick compatibility and specs at a glance
Choose by MCU core, I/O count, wireless support, and form factor. Below is a compact spec comparison of typical boards Communica stocks so you can match a board to your project needs.
| Board | Core | Flash / RAM | Connectivity | Typical use |
|---|---|---|---|---|
| Arduino Uno | ATmega328P | 32KB / 2KB | USB | Learning, low-pin projects |
| Raspberry Pi Pico | RP2040 | 264KB / 8MB (Flash external) | USB | Fast GPIO, PIO tricks |
| ESP32 Dev Kit | Xtensa Dual-core | 4MB / 520KB | Wi-Fi + Bluetooth | IoT, wireless sensors |
Selection criteria: how to decide
- Compute & memory: pick RP2040 or ESP32 for heavier signal processing or multitasking.
- Connectivity: choose ESP32 for Wi-Fi/Bluetooth; add an external module for LoRa or cellular.
- GPIO & ADC: count analogue inputs and PWM channels needed for sensors or motor drivers.
- Power & peripherals: check power rails (3.3V/5V), USB vs battery support, and available serial/UARTs.

Accessory bundles and compatibility guidance
We recommend pairing boards with these essentials: a reliable 5V/3A PSU or 3.7V LiPo charger, logic-level MOSFETs for motor control, and a USB-to-UART adapter for bootloading/debugging. Communica bundles common matchings so you avoid voltage or pinout surprises - each bundle lists supported boards and connectors to ensure compatibility with the selected MCU family.
