Teensy 4.0 Development Board The Teensy 4.0 features an ARM Cortex-M7 processor at 600 MHz, with an NXP iMXRT1062 chip, the fastest microcontroller available today – ten times faster than the Teensy 3.2! The NXP iMXRT1062 is a ‘cross-over’ processor, which has the functionality of a microcontroller, at the speeds of a microcomputer. It’s perfect for when you need tons of flash, RAM and, crunch lots of data, or when you need two full-speed USB ports. It even has a graphics processor! All this for two sawbucks. When running at 600 MHz, Teensy 4.0 consumes approximately 100 mA 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 & time while the power is off. Teensy 4.0 also can also be overclocked, well beyond 600 MHz!

Teensy 4.1 Development Board The Teensy 4.1 is the newest iteration of the astoundingly popular development platform that features an ARM Cortex-M7 processor at 600MHz, with an NXP iMXRT1062 chip, four times larger flash memory than the 4.0, and two new locations to optionally add more memory. The Teensy 4.1 is the same size and shape as the Teensy 3.6 (2.4in by 0.7in) and provides greater I/O capability, including an ethernet PHY, SD card socket, and USB host port. When running at 600 MHz, this Teensy board consumes approximately 100mA current and provides support for dynamic clock scaling. Unlike traditional microcontrollers, where changing the clock speed causes wrong baud rates and other issues, Teensy 4.1 hardware and Teensyduino’s software support for Arduino timing functions are designed to allow dynamic 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 microcontroller 4.1 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 five seconds and being turned back on by a brief button press. If a coin cell is connected to VBAT, this board's RTC also continues to keep track of the date & time while the power is off. Teensy 4.1 also can also be overclocked, well beyond 600MHz! Teensy 4.1’s Cortex-M7 processor includes a floating-point unit (FPU) that supports both 64-bit “double” and 32-bit “float”. With M4’s FPU on Teensy 3.5 & 3.6, and also Atmel SAMD51 chips, the only 32-bit float is hardware accelerated. Any use of double, double functions like log(), sin(), and cos() means slow software-implemented math. The 4.1 Teensy development board executes all of these with FPU hardware. Features ARM Cortex-M7 at 600MHz 1024K RAM (512K is tightly coupled) 8 Mbyte Flash (64K reserved for recovery & EEPROM emulation) USB Host Port 2 chips Plus Program Memory 55 Total I/O Pins Cryptographic Acceleration Random Number Generator RTC for date/time Programmable FlexIO Pixel Processing Pipeline Peripheral cross triggering Power On/Off management Pin diagram Applications: Ideal for robotics, automation, and motor control systems. Suitable for audio processing, DSP, and real-time audio manipulation applications. Best for data logging and acquisition systems. Enables IoT devices, web servers, and networked sensors. Suitable for secure communication and data encryption applications. Ideal for image processing, computer vision, and display systems. Provides versatility for interfacing with sensors, actuators, and peripherals. Allows for the development of tailored embedded systems and prototypes. All about Teensy 4.1 Development Board

Thermistor Temperature Sensor HT-NTC100K- 2M NTC type temperature sensor 10K 1% with Two tinned copper wire cables consists of NTC element, SUS housing, two tinned wire cable, terminal, and temperature probe. The sensor is protected by a rubber or a stainless steel capsule, both waterproof. It is a proper solution for either heating or cooling applications. Thermistor temperature measurement is stable. The temperature measurement of the upgraded HT-NTC100K can be up to 350 degrees, can effectively replace the K-type thermocouple. It helps much to solve the issues of strict requirements of K-type thermocouple wiring, and the line is long which is susceptible to get external interference and results in temperature fluctuation that can affect the printing quality. If need to print high-temperature filament, the HT-NTC100K thermistors are highly recommended. Applications: Household air conditioner Solar water heater Refrigerator Stove Induction cooker Electric oven Home appliances Floor heating 3D printers

Thermoelectric Peltier Refrigeration Cooling System DIY Kit With TEC-12706 Peltier Semiconductor coolers are a form of solid-state cooling that incorporates both semiconductor technologies and electronic assembly techniques. The thermoelectric Peltier refrigeration cooling system DIY kit is one such example. The DIY kit is a semiconductor cooling kit that uses a TEC1-12706 Thermoelectric Cooler Peltier Module. The kit has 2 heat sinks, the bigger one is for the hotter side and the smaller one is for the cooler side. The bigger the heat sink, the greater dissipation of the heat. The fan, also included in this kit acts as a radiator. This is attached to the bigger heat sink . The TEC1-12706 thermoelectric Peltier module is sandwiched between the two heat sinks. The module will reduce the temperature. Note: This is an unassembled kit. How To Assemble The Thermoelectric Peltier Refrigeration Cooling System DIY Kit: First, take the large heatsink and the cotton washer (which will hold the Peltier in place), remove the cotton washer’s sticker and place it on top of the large heat sink, making sure to align it. Apply thermal grease or heatsink compound before installing the TEC1-12706 Peltier module (the heatsink compound/thermal grease increases the heat transfer rate). Then, firmly press the TEC1-12706 Peltier module against the heatsink (Remember the cold side of the Peltier module is always the surface with letterings) Apply the heatsink compound/thermal grease above the TEC1-12706 Peltier module and place the small heatsink on top of it and attach the screws Place the brushless dc fan on top of the large heat sink, align it properly, and screw it in place.

Tilt Sensor Tilt sensors allow you to detect orientation or inclination. They are small, inexpensive, low-power and easy-to-use. If used properly, they will not wear out. Their simplicity makes them popular for toys, gadgets and appliances. This sensors is a solution for where you need detect when something has shifted from it’s desired orientation. It’s a simple ball-in-a-sleeve that when rolled to one end closes a contact. Actually, it’s a pair of balls, the second ball reinforces the bridging of the contacts by the first ball. In it’s simplest application, it could be hung straight down and would close only if it were swung over 90° in any orientation. Team up 2 or 3, adjust the angles, and you could have it report when orientation shifts past any one of their angles. Sort of a really poor-man’s gyro/g-force sensor. Note: The orientation of the pins will affect the responsiveness of the sensor. Laid horizontally, the balls will bridge the sensor pins much more easily than if the pins are laid vertically. check out : KY-010 Broken Light Blocking Sensor Applications: To detect the position of hand-held game systems and in game controllers To indicate the roll of boats, vehicles and aircraft To measure the angle at which a satellite antenna 'looks' toward a satellite To estimate the height of a tree or building To measure the steepness of a ski slope To provide a warning system for the surface tilt angle of cryogenic liquids during transportation To monitor laser levels and seismic activity
