Find local stock of components, development boards, sensors and kit bundles for makers, students and engineers. Branch pickup, quotes and VAT invoices available.
Buy components with branch collection and VAT invoices for education procurement.
Preselected board, power and sensor bundles simplify classroom and hobby builds.
Compare voltages, interfaces and connector types before ordering.
Sourcing electronic components locally reduces lead times, simplifies VAT invoicing for schools and projects, and makes branch collection or quick courier delivery possible. Communica stocks semiconductors, passives, sensors, connectors and popular development boards so makers and educators can assemble kits without international delays. For an overview of the company and its services see About Us.
Communica maintains a wide brand range, from maker-favourite modules to industrial component lines. Browse product categories to match components to your kit needs: Shop by Category. Popular choices for DIY kits include low-cost microcontrollers, Adafruit-compatible modules, and basic sensor suites. Availability varies by branch; check stock in Samrand or arrange branch collection via the branches page: Branches & Trading Hours.
When selecting parts for a DIY kit, verify key specs to avoid compatibility issues. For example:
| Component | Key specs to check | Why it matters |
|---|---|---|
| Microcontroller / board | Voltage, I/O count, form factor | Ensures peripheral compatibility and power requirements |
| Power supply / adapter | Output voltage, current rating, connector type | Prevents undervoltage or component damage |
| Sensors | Interface (I2C/SPI/analog), operating voltage, range | Matches board interfaces and expected measurements |
If you need a quick parts list or to compare items, use the product index: All Products to filter by category and brand.
Tip: For education kits, request VAT-inclusive invoices and bundle quotes to simplify procurement for schools and tertiary projects.
When assembling DIY kits, group components into functional bundles: core board + power + sensor pack + connectors. Bundles reduce picking errors and simplify classroom distribution. Example bundle pricing (illustrative): a microcontroller board (approx. ZAR 350-800), basic sensor set (ZAR 150-400) and power adapter (ZAR 80-250). Prices are estimates and subject to stock; request a quote for accurate ZAR totals and bulk discounts.
Basic wiring for a microcontroller powering a sensor and a servo might look like:
Microcontroller 5V -----+---- Servo V+ (5V, 500mA peak)
|---- Sensor V+ (5V, 50mA)
+---- 5V power supply
GND ---------------------+---- Servo GND and Sensor GND
I/O pins ---------------- Control signals
Use Ohm's law and power formulas to check if your supply can handle peak currents. Example: If servo peak current = 500mA and sensor = 50mA, choose a 5V supply rated above (0.5 + 0.05) A = 0.55 A - a 1 A supply provides margin. P = V x I, so 5V x 1A = 5W.
Use Communica account quoting for bulk school purchases, request VAT invoices, and choose Samrand pickup to save time. If you need brand-focused components, explore maker and industrial brands on the shop-by-brand page: Shop by Brand. To compare parts before buying, use the product filters and specifications tables in the collections area: Compare Specs.
