Hello everyone, and welcome back to another Friday Product Post here at SparkFun Electronics! This week, we have two brand new IoT boards for you to check out, the first of which is our new USB-C version of our ESP32-WROOM Thing Plus. As the name implies, this board replaces the micro USB port on the board with a USB-C, it adds a microSD card slot, and it adds two new voltage regulators for better power use! Following that, we have a new Arduino R3 footprint IoT RedBoard equipped with an ESP32-WROOM as well! A lot of the features that are on the new Thing Plus this week. So, if an R3 version is more your style, you have options. Teensy is up next with 4.1 versions of the popular development board, just without Ethernet. This is a simple change due to supply constraints, but you’ll be able to pick up these new versions of the Teensy 4.1 with or without headers. Finally, we wrap the week with a new miniature through-hole speaker. Now, let’s jump in and take a closer look at all of this week’s new products!
USB-C, microSD, and more!
The SparkFun ESP32 WROOM Thing Plus with USB-C is a great place to get started with Espressif IoT ideations while still enjoying all the amenities of the original ESP32 WROOM Thing Plus. Espressif’s ESP32 WROOM is a powerful WiFi and Bluetooth® MCU module that targets a wide variety of applications. At the core of this module is the ESP32-D0WDQ6 chip which is designed to be both scalable and adaptive. To make the Thing Plus as easy to use as possible, we’ve made the board Feather-compatible and it utilizes our handy Qwiic Connect System which means no soldering or shields are required to connect it to the rest of your system!
Now you can use an ESP32-WROOM in an Arduino R3 footprint!
The SparkFun IoT RedBoard is an ESP32 Development Board that includes everything but the kitchen sink! Espressif’s ESP32 WROOM is a powerful WiFi and Bluetooth® MCU module that targets a wide variety of applications. At the core of this module is the ESP32-D0WDQ6 chip which is designed to be both scalable and adaptive. The IoT RedBoard can target a wide variety of applications, ranging from low-power sensor networks to the most demanding tasks, such as voice encoding, music streaming, and MP3 decoding. The IoT ReadBoard also utilizes our handy Qwiic Connect System which means no soldering or shields are required to connect it to the rest of your system!
The Teensy 4.1s (your choice of with headers or without them) are 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. 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 SD card socket, and USB host port. Please keep in mind that these Teensy 4.1 versions do not have Ethernet capabilities.
Last up this week is this small, 15mm round speaker that operates around the audible 2kHz range. You can use these speakers to create simple music or user interfaces and is great for projects where you don’t have room for a full-blown speaker.
That’s it for this week. As always, we can’t wait to see what you make. Shoot us a tweet @sparkfun, or let us know on Instagram, Facebook or LinkedIn. Please be safe out there, be kind to one another, and we’ll see you next week with even more new products!
Never miss a new product!
