Summary of TEENSY 4.1 IS THE FIRST MICROCONTROLLER BOARD TO COME WITH 100MBIT ETHERNET COUPLED WITH 600MHZ 32- BIT MICROPROCESSOR
Teensy microcontroller boards are compact, Arduino-compatible development platforms based on high-performance 32-bit ARM chips. The new Teensy 4.1 expands on the 4.0 by offering more I/O, memory, GPIOs, and fast 100 Mbit Ethernet while retaining the platform's real-time capabilities with a 600 MHz Cortex-M7 core. PJRC positions the 4.0 and 4.1 for different use cases: 4.0 for projects needing less memory/I/O, and 4.1 for applications requiring Ethernet, extra peripherals, USB device connections, or fast SD card access.
Parts used in theTeensy 4.1:
- Teensy 4.1 development board (600 MHz Cortex-M7)
- Fast 100 Mbit Ethernet interface
- Additional GPIO pins
- Expanded memory (on-board)
- USB device connection port
- SD card interface for fast access
Teensy is another line of microcontroller boards designed to offer maximum I/O capabilities backed up by fully featured software libraries to run on Arduino. Loved by makers around the world for a number of reasons, these Arduino compatible boards have proven to be an astounding development platform in a small form capable of implementing many types of projects.
They are usually built around high-performance 32-bit ARM chips that offer faster clock speeds, expanded set of hardware peripherals, and extended serial communication ports.
Just like other popular platforms, Teensy development boards have gone through many iterations each with different computing power, pins, and performance specifications. Just last year, the Teensy 4.0 priced at $19.95 was released, and now v 4.1, an update of the already mighty 4.0 has been added to the league.
One big addition to the newly released Teensy 4.1 is the fast Ethernet to support low latency and high bandwidth applications. It is a bigger size than the 4.0 but adds more peripherals, memory, and GPIOs. PJRC, however, says that both Teensy 4.1 and 4.0 serve different segments of the market, so one is not a replacement for the other.
“Not every project requires so much or extra memory. Teensy 4.0 fills those needs. But when you do need more I/O, more memory, fast Ethernet, or connecting USB devices or fast SD card access, the larger Teensy 4.1 brings this extra I/O capability to a platform designed for real-time use with fast 600 MHz M7 performance.”
