SparkFun has released two new development boards built around the Espressif ESP32-WROOM module, including one, the ESP32-WROOM Thing Plus with USB-C, which upgrades a limited-run SparkX design to an official product line.
“The SparkFun ESP32-WROOM Thing Plus with USB-C brings some improvements to the previous ESP32 Thing Plus,” the company says of its latest board release. “In addition to the standard Thing Plus form factor, we’ve included a µSD [microSD] card slot, upgraded to USB-C connector, integrated RGB status LED and battery charge gauge, and provided two voltage regulators; a separate 700mA current source for the Qwiic board and connector.”
If this feature set sounds familiar, that’s because this is the design’s second release after being tested under the company’s SparkX brand as the ESP32 Thing Plus C. Where the SparkX products come with limited support and no guarantee of continued availability beyond an initial production run, however, the new ESP32-WROOM Thing Plus is a commodity product, as seen in the trademark red circuit board of the society.
For those unrelated to breadboard use or the Feather-enabled Thing Plus ecosystem, SparkFun has also launched a new RedBoard IoT based on ESP32 WROOM for the Internet of Things (IoT). Using the familiar Arduino UNO layout, the board uses an ESP32-D0WDQ6 and comes preloaded with the FreeRTOS real-time operating system and Lightweight Internet Protocol (LwIP) stack – plus a microSD slot, JST connector for power battery, a Qwiic connector, and USB Type-C connector with CH340G USB to TTL serial bridge for data and power.
Both boards are available now on the SparkFun store at $24.95 for the ESP32-WROOM Thing Plus with USB-C or $29.95 for the ESP32 IoT Red Boardboth before volume discounts.
Those eager to grab a bargain can pick up the earliest SparkX ESP32 Thing Plus C for $21.95, while supplies last. Further information, meanwhile, is available in the ESP32-WROOM Thing Plus with USB-C and ESP32 IoT Red Board connection guides.
