Why price matters for your IoT project
Choosing an IoT kit is as much about cost control as capability. The right kit gives you enough I/O, connectivity and sensors to prove a concept, teach a class or deliver a pilot without overpaying for features you won’t use. Communica stocks a range of kits priced for hobbyists, tertiary labs and procurement teams - with local availability to reduce lead times and VAT-compliant invoices for institutional buys.
What you get for different price tiers
Below is a practical, real-world breakdown so you can match budget to outcome. These sample tiers reflect typical stock we carry and the accessory bundles that make deployment simple.
| Tier | Typical price range (ZAR) | Included highlights |
|---|---|---|
| Entry (makers & students) | ~R300-R1,200 | ESP32/Arduino Nano, single sensor, USB cable, breadboard jumper set |
| Developer (prototyping) | ~R1,200-R3,500 | ESP32 dev board, multiple sensors, relay/power module, enclosure options |
| Classroom / Pilot | ~R3,500+ | Bundle of 10+, power supplies, breakout shields, documentation pack |
Specification callouts to check before you buy
- Connectivity: Wi-Fi (2.4GHz) vs LTE vs LoRa - choose based on range and power.
- MCU capabilities: flash/ram and available GPIO for your sensors and actuators.
- Power needs: onboard regulator, supply voltage range and typical current draw.
- Bundled accessories: cables, headers, enclosures and mounting hardware save time.

Quick power calculation for battery projects
Estimate runtime using a simple formula: Runtime (hours) = Battery capacity (mAh) / Average current draw (mA). Example: a 2000 mAh LiPo powering an ESP32 that averages 80 mA gives ~25 hours. Factor in peak currents during Wi-Fi bursts and add 20-30% headroom for reliable operation.
