With M4's FPU on Teensy 3.5 \u0026amp; 3.6, and also Atmel SAMD51 chips, only 32 bit float is hardware accelerated. Any use of double, double functions like log(), sin(), cos() means slow software implemented math. Teensy 4.0 executes all of these with FPU hardware.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"line-height:1.7;text-align:left;text-indent:0;margin-left:0;margin-top:0;margin-bottom:0\"\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"line-height:1.7;text-align:left;text-indent:0;margin-left:0;margin-top:0;margin-bottom:0\"\u003e\u003cspan style=\"color:rgb(51, 51, 51);font-size:10.5pt\"\u003eNote: Please be aware that the Teensy 4.0 does not include headers and will need to be purchased separately and soldered on yourself.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"line-height:1.7;text-align:left;text-indent:0;margin-left:0;margin-top:0;margin-bottom:0\"\u003e\u003cspan style=\"color:rgb(51, 51, 51);font-size:10.5pt\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"line-height:1.7;text-align:left;text-indent:0;margin-left:0;margin-top:0;margin-bottom:0\"\u003e\u003cspan style=\"color:rgb(51, 51, 51);font-size:10.5pt\"\u003eThe Teensy 4.1 is the newest iteration of the astoundingly popular development platform that features an ARM Cortex-M7 processor at 600MHz, with a NXP iMXRT1062 chip, four times larger flash memory than the 4.0, and two new locations to optionally add more memory.
