Hello everyone and welcome back to another Friday Product Post here at SparkFun Electronics! We had another week of early new product releases thanks to Arduino's announcement of their two new UNO R4 boards and our Qwiic Kit that utilizes their WiFi version. Fun fact, the Minima is now in stock and shipping, the WiFi should be in stock and shipping as late as next week, and the Qwiic Kit should start shipping shortly after! This week we are also excited to announce our newest MicroMod Board, the STM32WB5MMG Processor! This is a much improved version of the STM32 processor that should make an excellent new addition to the MicroMod product line! Now, let's jump in and take a closer look at all of this week's new products!

OpenThread comes to MicroMod!

SparkFun MicroMod STM32WB5MMG Processor

SparkFun MicroMod STM32WB5MMG Processor


The MicroMod STM32WB5MMG Processor expands on SparkFun's MicroMod ST product line with a powerful combination of computing and wireless capabilities on one M.2-connectable processor. The STM32WB5MMG from STMicroelectronics is an ultra-low power microcontroller that combines a pair of Arm® Cortex® processors; a Cortex-M4 processor with FPU and ART for primary computing and a Cortex-M0 to run the 2.4 GHz RF stack. The module's radio is Bluetooth® Low Energy 5.3, Zigbee® 3.0, and OpenThread certified.

Arduino UNO R4 WiFi

The UNO universe expands with th UNO R4 WiFi: the same industry-standard form factor at 5V operating voltage, but with the enhanced performance of a RA4M1 32-bit microcontroller by Renesas with ESP32-S3-MINI coprocessor – for increased computational power, memory and speed – as well as Wi-Fi® and Bluetooth® connectivity, a 12 x 8 LED matrix, and a Qwiic connector.

Arduino’s continued commitment to making technology accessible to everyone was the inspiration behind the Arduino UNO R4 Minima: the new addition to the brand’s community-supported ecosystem offers powerful technology at an affordable price. Packing more computational power, memory and speed in the familiar form factor of the UNO at 5V operating voltage, it allows users to easily upgrade projects made with the UNO R3 or the Leonardo. What’s more, thanks to a RA4M1 microcontroller by Renesas, it can leverage two new off-the-shelf peripherals, CAN BUS and (12 bit) DAC: perfect for automation or audio projects.

The SparkFun Arduino UNO R4 WiFi Qwiic Kit is a great way to start with Arduino and the Qwiic-connect system. This kit includes everything you need to build a WiFi-enabled project, including an Arduino UNO R4 board, an assortment of Qwiic-enabled sensors and input boards, a Qwiic OLED Display, and a variety of other components to get you connected. Hooking up a handful of inputs and outputs to an Arduino UNO R4 has never been so easy.

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! We'll be back with more new products next week so make sure to check back then. Happy hacking!

Never miss a new product!
