Description
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!
The SparkFun ESP32 WROOM Thing Plus with USB-C provides a few enhancements to the previous ESP32 Thing Plus. In addition to the standard Thing Plus form factor, we have included a µSD card slot, upgraded to a USB-C connector, integrated a RGB status LED and battery fuel gauge, and provided two voltage regulators; a separate 700mA current source for the board and Qwiic connector. It's also important to point out that a CH340C serial-to-UART bridge is used on this board; unlike previous variants.
The ESP32 Thing plus integrates a rich set of peripherals, ranging from capacitive touch sensors, SD card interface, Ethernet, high-speed SPI, UART, I2S and I2C, etc. The module also features 16MB of flash memory, 520kB of internal SRAM, an integrated 802.11 b/g/n WiFi transceiver with dual-mode Bluetooth® capabilities, and a JST connector to plug in a LiPo battery.
