System STM32 Special

We released two new STM32 boards yesterday, but we still have plenty more to talk about this week!

Hello there! In case you missed it, yesterday we released two new boards that feature the STM32 - one in our MicroMod Processor footprint, the other in the Feather-compatible Thing Plus. These are some of the most powerful, fast boards that we currently offer, so make sure to take a closer look at those!

Over the past week, SparkX also released two new boards: a new version of the ESP32 WROOM now with USB-C, as well as a QwiicNES Breakout that allows you to use a classic NES controller in your next Qwiic project. We finish off the day with two new LoRa modules that you can incorporate into a board that you design. Let's jump in and learn more!

Thing Plus or MicroMod? What will you choose?

SparkFun MicroMod STM32 Processor

SparkFun MicroMod STM32 Processor


The SparkFun MicroMod STM32 Processor is ready to rock your MicroMod world with its ARM® Cortex®-M4 32-bit RISC core! This little processor board provides you with an economical and easy to use development platform if you need more power with minimal working space. With the M.2 MicroMod connector, connecting your STM32 Processor is a breeze. Simply match up the key on your processor's beveled edge connector to the key on the M.2 connector and secure it with a screw (included with all carrier boards). The STM32 is one of the most powerful microcontrollers available, so to be able to add it to your MicroMod Carrier Board is a huge advantage!

SparkFun Thing Plus - STM32

With a 32-bit ARM® Cortex®-M4 RISC core as seen above, the SparkFun STM32 Thing Plus brings power and precision to your projects. This Thing Plus comes flashed with the DFU bootloader, and to make the Thing Plus even easier to use, we've moved a few pins around to make the board Feather compatible. In addition, it utilizes our handy Qwiic Connect System, which means no soldering or shields are required to connect it to the rest of your system!

Thing Plus C - ESP32 WROOM

The ESP32 Thing Plus C is a comprehensive development platform for Espressif's ESP32. Like the 8266 and ESP32 Thing, the ESP32 Thing Plus is a WiFi-compatible microcontroller with support for both Bluetooth Classic (i.e. SPP) and Bluetooth low-energy (i.e. BLE, BT4.0, Bluetooth Smart), a Qwiic connector, and 21 I/O pins. Add to that a rich set of peripherals ranging from capacitive touch sensors, Hall sensors, SD card interface, Ethernet, high-speed SPIs, UARTs, I2S and I2C.

We took all the good from the original ESP32 Thing Plus and sprinkled on some more! USB C provides up to 2A, and it has an upgraded 16 MB flash ESP32 WROOM module, CH340 USB to serial IC, an onboard fuel gauge IC, and an onboard addressable LED perfect for as a multi-status LED. Oh, and the new taller reset and boot buttons are so much easier to push!

QwiicNES Classic


Did you know that the NES Classic Edition controllers look and feel very authentic to their original 1983 counterparts? The only difference is they're I²C compatible right out of the box! So we made this simple Qwiic-to-Classic adapter board to allow a NES Classic Edition to plug right in (using the Wii Nunchuck connector) and connect to your Qwiic compatible development board!

LoRa/FSK Transceiver Module - 915MHz (RFM97CW)

$9.95 $5.99

RFM97CW Sub-GHz radio transceivers are ideal for long range wireless applications. With high integration, the RFM97CW simplifies the peripheral materials needed in system design. The sensitivity up to - 138 dbm optimizes link performance for applications. In addition, the RFM97CW also supports the function of duty cycle operation mode, channel listening, high-precision RSSI, power on reset, squelch output, etc., which makes the application design more flexible and realizes product differentiation

LoRa Transceiver Module (RFM95CW)

LoRa Transceiver Module (RFM95CW)


The RFM95CW is an ultra-low-power, high-performance LoRa transceiver for various frequency of 137-1020 MHz wireless applications. The high integration of RFM95C simplifies the peripheral materials needed in the system design. The sensitivity up to - 148 dBm can optimize the link performance of applications.

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 or Facebook. We’d love to see what projects you’ve made! 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!
