Teensy 4.1 ARM Cortex-M7 NXP 600MHz, no Ethernet PHY, Arduino IDE compatible

Teensy 4.1 is powerful board with ARM Cortex-M7 running at blazing fast 600 MHz. Board is bigger than Teensy 4.0 and this allows to use much more IO. 55 digital pins (42 breadboard friendly, 7 as SMT pads). 35 of them can work as PWM output. 18 analog inputs (2 ADCs on chip).

This is No Ethernet version - regular Teensy 4.1 have Ethernet PHY on board, thus is enough to connect Ethernet kit and have great Ethernet connectivity. This version does not have Ethernet PHY on board, so no easy Ethernet interface.
