This chip integrates a Tensilica processor and a complete Wi-Fi stack, making it an excellent choice for Internet-connected projects and IoT development. Programming is straightforward using the Arduino IDE, and the board also comes preloaded with the NodeMCU Lua interpreter for those who prefer Lua-based development.\u003c\/p\u003e\n\u003cp\u003eFor fast and reliable programming, the Feather HUZZAH uses a SiLabs CP2104 USB-to-Serial converter, capable of upload speeds up to 921600 baud. Auto-reset is built in, so there’s no need to manually toggle pins or press reset buttons. Compared to common alternatives like the CH340, the CP2104 offers better driver support and stable operation at high speeds.\u003c\/p\u003e\n\u003cp\u003eDesigned with portability in mind, the board includes a connector for 3.7 V lithium polymer batteries and onboard battery charging. It can run directly from the micro-USB connector, or switch automatically to USB power when available while recharging the battery. This makes it ideal for projects that need to move seamlessly between desk and field use.\u003c\/p\u003e\n\u003cp\u003eEach Feather HUZZAH ESP8266 comes fully assembled and tested, with headers included so you can solder them on and plug the board straight into a breadboard. \u003cstrong\u003eLiPo battery and USB cable are not included\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003e\u003ciframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/KK-TJ4ovy2Y?si=aYehU_Y1qJ1Nk5Hg\u0026amp;start=6\" title=\"YouTube video player\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eESP8266 @ 80MHz with 3.3V logic\/power\u003c\/li\u003e\n\u003cli\u003e4MB of FLASH (32 MBit)\u003c\/li\u003e\n\u003cli\u003eBuilt in WiFi 802.11 b\/g\/n\u003c\/li\u003e\n\u003cli\u003e3.3V regulator with 500mA peak current output\u003c\/li\u003e\n\u003cli\u003eCP2104 USB-Serial converter onboard with 921600 max baudrate for speedy uploading\u003c\/li\u003e\n\u003cli\u003eAuto-reset support for getting into bootload mode before firmware upload\u003c\/li\u003e\n\u003cli\u003e9 x GPIO pins - can also be used as I2C and SPI\u003c\/li\u003e\n\u003cli\u003e1 x analogue inputs 1.0V max\u003c\/li\u003e\n\u003cli\u003eBuilt-in 100mA LiPoly charger with charging status indicator LED, can also cut a trace to disable the charger\u003c\/li\u003e\n\u003cli\u003ePin #0 red LED for general purpose blinking.

Teensy 4.0 is the same size and shape as Teensy 3.2, and retains compatibility with most of the pin functions on Teensy 3.2.\u003c\/p\u003e\n\u003cp\u003eWhen running at 600 MHz, Teensy 4.0 consumes approximately 100mA current. Teensy 4.0 provides support for dynamic clock scaling. Unlike traditional microcontrollers, where changing the clock speed causes wrong baud rates and other issues, Teensy 4.0 hardware and Teensyduino's software support for Arduino timing functions are designed to allow dynamically speed changes. 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. Teensy 4.0 also provides a power shut off feature. By connecting a pushbutton to the On\/Off pin, the 3.3V power supply can be completely disabled by holding the button for 5 seconds, and turned back on by a brief button press. If a coin cell is connected to VBAT, Teensy 4.0's RTC also continues to keep track of date \u0026amp; time while the power is off. Teensy 4.0 also can also be overclocked, well beyond 600MHz!\u003c\/p\u003e\n\u003cp\u003eThe ARM Cortex-M7 brings many powerful CPU features to a true real-time microcontroller platform. Cortex-M7 is a dual-issue superscaler processor, meaning the M7 can execute two instructions per clock cycle, at 600MHz! Of course, executing two simultaneously depends upon the compiler ordering instructions and registers. Initial benchmarks have shown C++ code compiled by Arduino tends to achieve two instructions about 40% to 50% of the time while performing numerically intensive work using integers and pointers. Cortex-M7 is the first ARM microcontroller to use branch prediction. On M4, loops and other code which much branch take three clock cycles. With M7, after a loop has executed a few times, the branch prediction removes that overhead, allowing the branch instruction to run in only a single clock cycle.\u003c\/p\u003e\n\u003cp\u003eTightly Coupled Memory is a special feature which allows Cortex-M7 fast single cycle access to memory using a pair of 64 bit wide buses. The ITCM bus provides a 64 bit path to fetch instructions. The DTCM bus is actually a pair of 32 bit paths, allowing M7 to perform up to two separate memory accesses in the same cycle. These extremely high speed buses are separate from M7's main AXI bus, which accesses other memory and peripherals. 512K of memory can be accessed as tightly coupled memory. Teensyduino automatically allocates your Arduino sketch code into ITCM and all non-malloc memory use to the fast DTCM, unless you add extra keywords to override the optimized default. Memory not accessed on the tightly coupled buses is optimized for DMA access by peripherals. Because the bulk of M7's memory access is done on the two tightly coupled buses, powerful DMA-based peripherals have excellent access to the non-TCM memory for highly efficient I\/O.\u003c\/p\u003e\n\u003cp\u003eTeensy 4.0's Cortex-M7 processor includes a floating point unit (FPU) which supports both 64 bit \"double\" and 32 bit \"float\". 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\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote\u003c\/strong\u003e: \u003cstrong\u003ePlease be aware that the Teensy 4.0 does not include headers and will need to be purchased separately and soldered on yourself\u003c\/strong\u003e - or grab the pre-soldered Teensy 4.0 here!\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eARM Cortex-M7 at 600MHz\u003c\/li\u003e\n\u003cli\u003e1024K RAM (512K is tightly coupled)\u003c\/li\u003e\n\u003cli\u003e2048K Flash (64K reserved for recovery \u0026amp; EEPROM emulation)\u003c\/li\u003e\n\u003cli\u003e2 USB ports, both 480MBit\/sec\u003c\/li\u003e\n\u003cli\u003e3 CAN Bus (1 with CAN FD)\u003c\/li\u003e\n\u003cli\u003e2 I\u003csup\u003e2\u003c\/sup\u003eS Digital Audio\u003c\/li\u003e\n\u003cli\u003e1 S\/PDIF Digital Audio\u003c\/li\u003e\n\u003cli\u003e1 SDIO (4 bit) native SD\u003c\/li\u003e\n\u003cli\u003e3 SPI, all with 16 word FIFO\u003c\/li\u003e\n\u003cli\u003e3 I\u003csup\u003e2\u003c\/sup\u003eC, all with 4 byte FIFO\u003c\/li\u003e\n\u003cli\u003e7 Serial, all with 4 byte FIFO\u003c\/li\u003e\n\u003cli\u003e32 general purpose DMA channels\u003c\/li\u003e\n\u003cli\u003e31 PWM pins\u003c\/li\u003e\n\u003cli\u003e40 digital pins, all interrrupt capable\u003c\/li\u003e\n\u003cli\u003e14 analog pins, 2 ADCs on chip\u003c\/li\u003e\n\u003cli\u003eCryptographic Acceleration\u003c\/li\u003e\n\u003cli\u003eRandom Number Generator\u003c\/li\u003e\n\u003cli\u003eRTC for date\/time\u003c\/li\u003e\n\u003cli\u003eProgrammable FlexIO\u003c\/li\u003e\n\u003cli\u003ePixel Processing Pipeline\u003c\/li\u003e\n\u003cli\u003ePeripheral cross triggering\u003c\/li\u003e\n\u003cli\u003ePower On\/Off management\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\nDatasheet\u003cspan\u003e \u003c\/span\u003e(MIMXRT1062 DVL6A)\u003c\/li\u003e\n\u003cli\u003e\nManual\u003cspan\u003e \u003c\/span\u003e(MIMXRT1062 DVL6A)\u003c\/li\u003e\n\u003cli\u003e\nDatasheet\u003cspan\u003e \u003c\/span\u003e(W25Q16JV-DTR)\u003c\/li\u003e\n\u003cli\u003eTeensy Quick Start\u003c\/li\u003e\n\u003cli\u003eTeensyduino Software\u003c\/li\u003e\n\u003cli\u003ePin Assignment Charts\n\u003cul\u003e\n\u003cli\u003eFront\u003c\/li\u003e\n\u003cli\u003eBack\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eTeensy Help Page and FAQ\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePackage Contents\u003c\/h2\u003e\n\u003cp\u003e1x Teensy 4.0 board\u003c\/p\u003e","brand":"PJRC","offers":[{"title":"Default Title","offer_id":54079464833135,"sku":"rqc1787257829995","price":16.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0637\/3376\/0111\/files\/teensy-40_1.jpg?v=1787257838"},{"product_id":"assembled-dc-motor-stepper-featherwing-add-on","title":"Assembled DC Motor + Stepper FeatherWing Add-on","description":"\u003cp\u003eA Feather board without ambition is a Feather board without FeatherWings!
