Is Teensy 4.1 ARM Cortex-M7 Ethernet Board Compatible with Arduino Ecosystem?
Electrical Specifications
Always confirm pin assignments against the manufacturer datasheet before wiring.
Compatibility Overview
600MHz ARM Cortex-M7 development board featuring native 100Mbit Ethernet hardware PHY and SD card slot for ultra-fast telemetry.
Typical SPI Wiring Reference
Standard SPI signal names. This is a bus reference, not a pinout for this specific board — check the silkscreen and datasheet for its actual pin order.
Reference circuit only. A shifter is needed when the host and peripheral run at different logic levels — check both datasheets to confirm whether this applies to your pairing.
