Why order breakout boards, shields and modules from Communica
Get the parts that move your project from prototype to proof-of-concept without week-long lead times. Communica stocks a wide selection of Arduino and Raspberry Pi shields, ESP32/MCU boards, sensor modules and power shields so you can test faster. Local stock reduces delivery uncertainty for students, labs and procurement teams who need VAT invoices, branch collection and predictable availability.
Secure local availability and practical benefits
Order online and choose Same-Day pickup from Samrand, Pretoria CBD or Cape Town branches to keep schedules tight. For account customers we issue formal quotes and VAT invoices for college or departmental purchasing. Need brand choice?

Typical use-cases where local stock matters
- Classroom labs - replace broken sensor modules between sessions.
- Rapid prototypes - swap MCU boards and shields during iteration.
- Repair & test benches - keep spare comms and power modules on the shelf.
Spec callouts to check before you order
Always confirm these attributes on the product page: operating voltage, logic level (3.3V vs 5V), pinout compatibility, and required libraries. You can compare categories and filter by specification in our collections area at Collections to narrow choices by interface (I2C, SPI, UART), form factor and power needs.
Quick spec comparison table
| Module | Logic | Interface | Notes |
|---|---|---|---|
| ESP32 Dev Board | 3.3V | Wi-Fi / Bluetooth / GPIO | Choose CP2102 or CH340 USB variant |
| Raspberry Pi HAT | 3.3V | GPIO / I2C / SPI | Check HAT EEPROM & driver support |
| Soil Moisture Sensor | Analog or Digital | ADC / Digital out | Calibrate for local soil types |
