Teensy 4.0 and Teensy 4.1 are some of the most powerful microcontroller-class boards you’ll find on the market thanks to NXP i.MX RT1062 Arm Cortex-M7 crossover processor clocked at up to 600 MHz, and there won’t break the bank are PJRC sells those for $20 and up on their own store or Amazon. If you’re into 3D printers, CNC, or pick-and-place machines, you’ll be glad to learn Teensy 4.1 board is the first Arm Cortex-M7 board to support Marlin 2.0 firmware, and a person nicknamed CrazzyFrenchDud is developing PeeNaPle breakout board for Teensy 4.1 to work with OpenPnP open-source software. The initial commit to Marlin firmware was made on September 10 for both Teensy 4.0 and 4.1 boards, but the title was changed to Teensy 4.1 only since Teensy 4.0 is not supported at this time, and may not be suitable for many 3D printers due to a lack of pins. Teensy 4.1 is much faster than existing boards support […]
