Description
The DEV-20359 is Teensy 4.1 without Ethernet Development Board integrates an ARM Cortex-M7 processor at 600MHz, with a NXP iMXRT1062 chip. The Teensy 4.1 is the same size and shape as the Teensy 3.6 (2.4in by 0.7in), and provides greater I/O capability, including an SD card socket, and USB host port.
Teensy 4.1 hardware and Teensyduino's software support for Arduino timing functions are designed to allow dynamically speed changes. Serial baud rates, audio streaming sample rates, and Arduino functions like delay() and millis(), and Teensyduino's extensions like IntervalTimer and elapsedMillis, continue to work properly while the CPU changes speed.

FAQs:
Q: What are the key differences between the Teensy 4.1 and Teensy 4.1 without Ethernet?
A: The primary difference is the absence of the Ethernet port in the "Teensy 4.1 without Ethernet" version. This makes it slightly more affordable and compact, but it loses the wired networking capability.
Q: Can I still use the Teensy 4.1 without Ethernet for network-connected projects?
A: Yes, you can use external modules like Wi-Fi or LoRa modules to add wireless connectivity to your projects.
Q: Does the Teensy 4.1 without Ethernet have the same processing power as the regular Teensy 4.1?
A: Yes, both versions have the same powerful 600MHz ARM Cortex-M7 processor, 1024K RAM, and 8MB Flash memory. They only differ in the absence of the Ethernet port.
Q: What are the advantages of using Teensy 4.1 without Ethernet?
A: The main advantages are its lower cost compared to the regular Teensy 4.1 and its smaller size due to the lack of an Ethernet port. This can be beneficial for projects where space is limited or budget is a concern.
Q: What applications is the Teensy 4.1 without Ethernet suitable for?
A: It is suitable for a wide range of applications, including audio/visual processing, machine learning, robotics, data logging, and high-speed control systems. While it lacks built-in Ethernet, you can still use it for projects that don't require wired networking or can utilize external wireless modules.
