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.

Unlock Network Connectivity for Your Arduino Projects

Arduino Ethernet boards and shields enable your microcontroller projects to communicate reliably on a standard wired network. Whether you're building remote monitoring, smart automation, industrial controllers, or classroom IoT demos, Communica makes sourcing Ethernet-enabled Arduino hardware easy and efficient for South Africa's makers, educators, and engineers.

Arduino Ethernet Options: From Shields to Integrated Boards

You'll find two main Ethernet solutions:

Original Arduino Ethernet Board (based on Wiznet W5100 chipset, integrates microcontroller and RJ45)
Arduino Ethernet Shield - plugs onto Arduino Uno, Mega, and compatibles

Popular global brands like Arduino, Seeed Studio, and DFRobot are regularly stocked at Communica, with full technical specs and accessory support.

Tip for South African Users: Shields and boards are available for online orders and branch collection. Most kits include pin headers; check for bundled cables or PoE modules according to project requirements.

Key Features at a Glance

Product	Microcontroller	Ethernet Chip	Pinouts	PoE Support
Arduino Ethernet Board	ATmega328P	W5100	Uno-compatible	With PoE add-on
Ethernet Shield v2	(Uses host board)	W5500/W5100	Stackable headers	Optional

Both options work well for low-latency, robust networked applications - compare specs or ask Communica's support for application guidance.
