How do I choose a microcontroller or single-board computer for a robotics prototype?

Match the controller to your project's compute needs, I/O count, and communication interfaces (GPIO, PWM, UART, SPI, I2C, CAN). Consider power budget, real?time requirements, available development libraries and community examples (e.g., Arduino, Raspberry Pi families), and confirm part availability and datasheets on the product page before ordering.

What should I check when selecting motors and motor drivers for robots?

Select motors based on required torque, speed, voltage and continuous vs stall current, and pair them with drivers rated for the motor's peak current and control method (brushed, brushless, stepper). Review datasheets for torque curves and cooling needs, and account for gearing, feedback sensors and the controller interface when planning your drivetrain.

Can I collect orders from a Communica branch and obtain a VAT invoice for institution purchases?

Yes — branch collection is available from the Samrand head office and branches in Pretoria (CBD) and Cape Town; choose the branch pickup option at checkout and present your order reference and ID on collection. VAT invoices can be issued for business or educational purchases; request invoice details at checkout or via the sales channel used for your order.

What are typical lead times for out?of?stock components and how do backorders work?

Many items are stocked locally, but specialist components may have supplier lead times; the product page normally shows current stock status and any estimated ETAs. For procurement or bulk needs you can request a quote or backorder option to confirm delivery timelines and minimum quantities.

Does Communica support educational or classroom robotics kits and bulk procurement for tertiary institutions?

Communica offers component kits, development boards, 3D printing supplies and test equipment suitable for classrooms and labs, and can provide bulk quotations and VAT invoicing for institutions. Check the education requirements when requesting a quote to ensure kit content, quantities and delivery or branch pickup options meet your curriculum needs.

What types of robotics and prototyping components does Communica stock?

Communica stocks microcontrollers and development boards, sensors, motors and drivers, power supplies, connectors and enclosures, 3D printing consumables, tools, and test & measurement equipment from a wide range of global and maker brands. Product availability can be checked on the online catalogue or by contacting your local branch.

How can I check stock availability and estimated lead times for parts?

Check the product page on communica.co.za for current stock indications and lead-time notes, and contact the Samrand head office or your nearest branch for confirmation on backorders or import lead times. For larger or time-sensitive orders, request a formal quote or lead-time confirmation from sales so you have a documented delivery estimate.

Can I collect my order from a Communica branch or do you only ship?

You can choose branch collection (Samrand, Pretoria CBD, Cape Town) or courier delivery at checkout; branch trading hours and collection details are listed on the Branches & Trading Hours page. For branch collection request a VAT invoice or packing slip at pickup.

Do you support educational and bulk procurement for robotics courses or labs?

Yes — Communica supplies schools, universities and industry with component kits and larger quantities; departments should contact the sales team with a parts list and delivery requirements to obtain volume quotes, lead times, and VAT-compliant paperwork. Early engagement helps manage stock allocation and import lead times for semester planning.

How do I choose the right motor and driver for a mobile robot prototype?

Match motor voltage and continuous/peak current ratings to the driver specification and battery system, and select torque and RPM based on robot weight, wheel diameter, and required acceleration; include a safety margin for stall current and thermal dissipation. Review datasheets, estimate your power budget, and confirm component availability or compatible alternatives with Communica before finalising the design.

Local Stock & Pickup

Samrand, Pretoria and Cape Town branches with quick collection options.

Education & Procurement

VAT invoices, account quotes and bundled kits for labs and courses.

Compatibility Support

Specification guidance, wiring diagrams and like-for-like alternatives.

Why choose Communica as your drone-stockist

Communica offers immediate access to core drone components and development hardware from our Samrand warehouse and branches - so your prototype or training course doesn’t stall on long lead times. We prioritise reliable local stock, clear spec guidance and VAT invoicing for education and procurement accounts. Shop Now or Check Stock in Samrand to confirm availability before you commit.

What we stock and who it’s for

From basic FPV kits to modular quadcopters for research, our selection covers flight controllers (including popular open designs), ESCs, brushless motors, propellers, LiPo batteries, GPS modules, telemetry radios, and protective enclosures. That makes us the practical choice for South African makers, tertiary students, technicians and procurement teams who need quick replacements, class kits or one-off prototype runs.

Local availability and branch pickup

Order online and collect from Samrand, Pretoria CBD or Cape Town branches to avoid courier delays. See branch hours and collection details on our Branches & Trading Hours page here. We also support account quotes and VAT invoices for institutional purchases and student projects.

Specification callouts - what to check first

Before buying: confirm frame size (diagonal motor-to-motor mm), propulsion match (motor KV to propeller and ESC continuous current), battery chemistry and C-rating, and flight controller protocol compatibility (PWM, DShot, SBUS, etc.). Use our order-drone-online compatibility guidance to build kits that work together and minimise troubleshooting time.

Component	Key spec to check	Why it matters
Motor	KV, max A	Matches prop and ESC for efficient thrust
ESC	Continuous current, firmware protocol	Protects motor and enables accurate control
Battery	Cell count (S), capacity (mAh), C-rating	Determines flight time and discharge capability

Explore component ranges and supply depth on our drone-in-stock Collections page here to plan a full parts list.

Compatibility guidance, accessory bundles and common builds

For education labs we recommend pre-configured bundles: frame + motors + ESCs + props + flight controller + battery + charger. Bundles reduce mis-matched parts and speed up classroom setup. For hobby builds, pair motor KV to prop size: lower KV (e.g., 900-1400) with larger props for efficiency; higher KV (2000+) suits small props and racing builds. Compare Specs when choosing between options.

      LiPo + -----+-----------------------+ (power distribution)
                |                       |
             PDB/ESC                 FC (GND)
         +---+---+---+              +---+
         | M1| M2| M3| M4|   signal ->|FC | (PWM / DShot)
         +---+---+---+              +---+

Ensure ESC ground shares with the flight controller ground; telemetry and RC receiver connections must use the correct signal voltage levels (3.3V vs 5V). For detailed wiring and connector types, view our tools and supplies in the Collections index here.

Troubleshooting and practical tips

If a motor stutters: verify ESC protocol and motor wiring, test with a bench supply, and check props for balance. If a controller won’t bind, confirm receiver mode and telemetry baud rates. For battery sag concerns, use this power calculation:

Power (W) = Voltage (V) × Current (A). Example: a 4S LiPo (14.8 V) drawing 30 A means ~444 W. Match ESC continuous rating above expected draw with 20-30% safety margin.

Scenario	Quick check
Short flight times	Increase battery capacity or reduce prop size/KV mismatch
Controller resets	Check power distribution and UBEC/5V regulator output
RC lag	Inspect antenna placement and receiver protocol

Why Communica works for South African teams

We combine wide brand breadth with practical local support: same-day pickup from Samrand in many cases, branch collections in Pretoria and Cape Town, and documentation to support education purchases. Learn about our history and service approach on the About Us page here.
