Teensy 4.1 (With Pins)

Product Information

to keep date / time while power is off Power USB Power Normally Teensy is powered by your PC or USB hub, through a USB cable.

It has multiple serial ports in addition to the main one for connecting to my workstation for uploading programs and watching the monitor port, and it has three I2S ports built in and ready to be used with the modified Arduino libraries. Form factor doesn’t justify by abusing such a powerful MCU or kind of a bridge between MCU and a microprocessor without giving enough pinouts and properly taking out it’s power out for users. It is formatted into a very compact ‘teensy’ board outline for easy embedding into projects or for use with solderless breadboards. It’s easy to think of this as a lot for a microcontroller, at least until you think about the power of this 600 MHz 32-bit processor and what people will want to do with it: audio and graphics applications can easily chew through the 1 MB, as can emulation of other processors/systems, such as for retro gaming. Since the board will already have Blink installed when you receive it, you might want to change the timing of the blink to verify the new download was successful.If you’re looking for an ultra-fast affordable microcontroller board that lives up to its Teensy name, the 4. It may be possible to convert the chip’s EUI-64 MAC address to EUI-48 depending on how the manufacturer handles a bunch of bits in the middle of the EUI-64 address. Please note that these will not plug into a solderless breadboard due to the additional headers on the bottom of the module. EXTMEM - Variables defined with EXTMEM are placed in the optional PSRAM memory chip soldered to the QSPI memory expansion area on bottom side of Teensy 4.

Serial baud rates, audio streaming sample rates, and Arduino functions like delay() and millis(), and Teensyduino’s extensions like IntervalTimer and elapsedMillis, continue to work properly while the CPU changes speed. That only leaves about 500ns (half a clock cycle) to launch an interrupt, resolve the address and output/input the data bus accordingly. These were left off the board for obvious reasons — even using a jack with integrated magnetics (magjack), it wouldn’t fit on the PCB.

This brings out an additional serial port, for a total of eight, plus additional analog and digital I/O.

It sounds awesome, but at the same time, lower end/cheaper microcontroller or raspberry pi would easily fill whatever area this is trying to accomplish. has been released, and using the same 600 MHz ARM Cortex M7 under the hood, is now also the fastest microcontroller board. is a mature product with the largest installed base and is in a small package format with 5V tolerant I/O and runs at 72MHz.
