Teensy 4.0

Among the fastest microcontrollers available today, Teensy 4.0 can run at 600 MHz and take up approximately 100 mA current while doing so. Teensy 4.0 also supports dynamic clock scaling. Teensy 4.0 is capable of being overclocked to 600 MHz. Teensy 4.0 hardware, Teensyduino software support for Arduino timing functions, and Teensyduino are designed to adapt to dynamic speed changes. This is in contrast to other microcontrollers that can change the clock speed and cause incorrect baud rates or other problems. Teensyduino’s extensions, such as IntervalTimer or elapsedMillis can be used to adjust the CPU speed. Teensy 4.0 has a power shut-off feature. One can connect a pushbutton at the On/Off pin and then hold the button down for five seconds to completely disable the 3.3V supply. Teensy 4.0’s RTC functionality (Real Time Clock), can keep track of date and time even when the power is off. As long as a coin cell has been connected to the voltage of a battery, it will also work.

Teensy 4.0 is faster than Teensy 3.6 and 15 times faster than Teensy 3.2. It also has multiple serial interfaces and peripherals such as three digital audio interfaces, three USB ports that transmit data at 480 Mbps, and three CAN buses.

There are some disadvantages to Teensy 4.0. It may look the same as the Teensy 3.2 board, but it’s much more functional. It costs $19.95, which is slightly more than Teensy3.2’s $19.80.

Teensy4.0 Projects: 

Teensy4.0 is an excellent choice for IoT projects such as audio synthesizer and analysis. Teensy 4.0, which is not a beginner-friendly board, can be a great choice for first-time makers. Teensy4.0 is a great choice for people who have been involved in IoT projects. It offers all the power of a Y2K desktop, at a fraction of the cost of boards that offer less horsepower.

The IoT boards that are cellular-enabled:

Particle Boron

A development board that lets one connect a mesh network to a cellular service, Particle Boron ( can act as a standalone cellular endpoint or LTE enabled gateway for Particle Mesh networks. It is based on the Nordic nRF52840 SoC, which is a System on a Chip. It’s basically the Electron with Bluetooth and meshes networking. It has two SARA cellular modules and NFC. There are also many GPIOs and LiPo charging. It can be used as either a standalone cellular gateway or LTE-enabled gateway for a Particle mesh network. The Boron can also be configured in Feather footprints and is compatible with Feather Shields. Boron access gives you access to the Device Cloud (up to 10 free micro networks) and three months of free device Cloud access via a cellular gateway.


Particle Boron has a big advantage over Particle Electron in that Particle Borons are able to communicate over WiFi with one another and then relay the information to a central station, which can be far away via a cellular network. The Boron is also less expensive than the Electron and offers features like header pins, LiPo connectors and buttons.


Particle Boron projects. The Particle Boron can be used as a gateway to connect a group of local endpoints to which Wi-Fi is not available or is unreliable. It is also great for connecting projects with the Particle Device Cloud.

Single Board Computers (SBCs)

BeagleBoard: BeagleBone Black

The BeagleBoard is a low-power open-source single-board computer produced by Texas Instruments in association with Digi-Key and Newark element14. It runs on Angstrom Linux and was created by a small group of engineers to be used in schools around the globe to teach open-source software and hardware. It is very similar to the Raspberry Pi in this sense.

The BeagleBone Black features include 512MB DDR3 RAM and 4GB 8-bit eMMC flash storage, 3D graphics accelerator, NEON floating point accelerator and 2x 32-bit PRU microcontrollers. It also has a USB client for power and communications, Ethernet, HDMI, and 2x 46 pin headers.


The BeagleBoard is simple to set up and easy to use, especially in the BeagleBone Black model. It uses very little power, so it doesn’t require any additional cooling or heat sinks. The BeagleBoneBlack has 65 input and output pins as well as a large number of interfaces. This makes it ideal for electronics projects. The PocketBeagle offers identical computing performance as the BeagleBoneBlack, with a 50 percent reduction of size, 75 percent weight reduction, and a 40 percent lower purchase price.


BeagleBoard projects – The BeagleBoard project is perfect for beginners in electronics or programming. Projects that require external sensors to read, command actuators (such as motors or light systems), and network are easier and more efficient using the BeagleBone Black rather than a Raspberry Pi.
