In-Stock: Popular Arduino Ethernet Products
| Product | Ethernet Chipset | Form Factor | Notes |
|---|---|---|---|
| Arduino Ethernet Shield 2 | W5500 | Shield (UNO/MEGA) | Official Arduino, PoE support |
| Wiznet W5100 Shield/Module | W5100 | Shield or module (various) | Widely compatible, well-supported libraries |
| ENC28J60 Module | ENC28J60 | PCB module | Value option, SPI interface |
| Pre-Assembled Arduino Ethernet Board | W5100/W5500 | Standalone | Integrated RJ45, minimal wiring |
What to Consider When Choosing Arduino Ethernet
- Board compatibility (UNO, MEGA, Nano) and shield pinout
- Ethernet chipset support (W5100: basic, W5500: higher speed/more connections, ENC28J60: cheaper, more DIY)
- PoE support (on select official Arduino Ethernet parts)
- Power requirements & connector type (USB, DC barrel)
- Physical space in enclosure or panel
- Library & software support for your development environment
Most shields stack directly onto an Arduino UNO or MEGA; module form factors require wiring via header pins (dupont leads or soldering advised). Look for RJ45 jack orientation and mounting constraints if deploying inside a case.
Network-Ready Feature Set
- 10/100 Mbps Ethernet (check model/specs)
- Hardware TCP/IP stack: W5100/W5500 variants offload network work from Arduino CPU
- Optional microSD card slot for data logging (on many shields)
- 3.3V/5V logic tolerance for direct connection to common Arduinos

Selection Guidance for South African Makers & Industry
When selecting Arduino Ethernet hardware in South Africa, consider factors such as immediate availability, documentation, power stability (SA's unique load shedding), and ready access to spare modules for rapid prototyping in labs, classrooms, and industry pilots.
Compatible Accessories at Communica
- Pre-crimped Cat5e/Cat6 Ethernet patch cables (various lengths)
- DIN-rail or wall-mount enclosures for networked projects
- Regulated power supplies (USB or DC, 2A+ recommended for shield+board stack)
- MicroSD cards (for data logging shields), jumpers, and socket headers
Check live stock of essential cables, SD cards, and power adapters when purchasing your Ethernet board to avoid project delays.
Stock, Lead Times & VAT Invoicing
- Product availability shown live on the Communica Arduino & Ethernet category
- Branch pickup: Order ahead and collect at Samrand HQ, Pretoria, or Cape Town (see branch trading hours)
- VAT invoices on all purchases for business, education & procurement
