Featuring the (presently) fastest microcontroller on the market, Teensy 4.1 more than quadruples the performance of the Teensy 3.6, and more than 6x faster than an ESP32, and still is Arduino IDE-compatible! In comparison to the Teensy 4.0, the 4.1 breaks out more peripherals and adds an easy to use USB header.

As usual, PJRC has broken out a great many features to this chipset:

  • ARM Cortex-M7 32-bit Processor @ 600MHz
  • 1024K RAM
  • 4096k FLASH (64k reserved)
  • 2 x USB ports at 480MBit/S (really? REALLY? USB that fast on a micro? Wow...)
  • 3 x CAN Bus (1 with FD)
  • 2 x I²S Digital Audio
  • 1 x S/PDIF Digital Audio
  • 1 x SDIO native SD (4 bit)
  • 3 x I²C with 4-byte FIFO
  • 7x Serial with 4-byte FIFO
  • 32 x general purpose DMA channels
  • 31 x PWM pins (remember having only 4 on an Uno?)
  • 40 x Digital I/O pins all interrupt capable
  • 14 x Analog pins, with 2 ADCs (on chip)
  • Cryptographic Acceleration
  • Random Number Generator
  • Real-Time Clock
  • Programmable FlexIO
  • Pixel processing pipeline
  • Peripheral cross triggering
  • Ethernet PHY
  • MicroSD Card Socket
  • Power On/Off management

Power consumption is also very manageable, being about 100mA in normal operation. Additionally, it supports dynamic clock scaling while maintaining proper timing across the peripherals. Serial and sampling rates work properly as you scale the CPU speed.
