What comes after Teensy 4.0? Teensy 4.1. The new version of the Arduino compatible board is powered by the same NXP i.MX RT1062 Cortex-M7 crossover processor clocked at 600 MHz, but about doubling in length in order to add a 10/100 Mbit Ethernet PHY, a MicroSD card slot, and offer more I/Os.
Teensy 4.1 also increases flash memory to 8 MB (vs 2 MB for Teensy 4.0), and the USB hot-plugging power management circuitry needed to plug a USB device via a USB host cable.
