Check if the module supports your microcontroller voltage. 3.3V modules need logic level shifters for 5V boards. Dual voltage modules save extra components.
Match the module to your board to avoid damage. Always check specs before wiring.
Connection Interface
SPI is standard for most Ethernet modules. It requires specific pins but allows fast data. Ensure your board has free SPI lines.
Some shields use direct pins. Consider pin availability on your board.
Socket Count
Multiple sockets allow concurrent connections. W5500 supports eight simultaneous sockets. ENC28J60 has fewer limits.
Plan for your max data streams. Higher socket counts increase flexibility.
Power Requirements
Modules vary in current draw. Ensure your power supply meets the minimum amp needs. Stable voltage prevents crashes.
Use regulated power for best results. Avoid relying solely on USB.
Physical Size
Compact modules fit small enclosures. Check PCB dimensions to ensure fit. Some shields are larger for ease of use.
Measure your space before buying. Consider mounting methods too.
Price vs Quantity
Multi packs offer better value per unit. If you need multiple devices, bulk buys save money. Single units are simpler for testing.
Balance cost with immediate needs. Bulk is efficient for prototypes.
Documentation Availability
Good tutorials ease setup. Look for brands with active communities. Clear pinouts help avoid mistakes.
Research support resources before purchase. Good docs save time later.
