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, Hall 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.
The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.
SparkFun Thing Plus - ESP32 WROOM Features

CHG- Yellow battery charging indicator
STAT- Blue status LED
ESP32-WROOM General Features:
If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

I've been working on a project for some time now using either ATTiny 85s or Arduino Uno's and Bluetooth modules to create a start timing horn system for sailboat racing. The combination of the Thing Plus ESP32 WROOM (USBC) and a Qwiic relay will get me to the final design size and functionality I've been looking for.
The onboard RGB LED and the built-in blue LED have helped me develop the code using the App built using MIT App Inventor as my interface via Bluetooth. Now that the Qwiic relay is back in stock, I should be able to pull it all together.
Thanks for offering this versatile and compact combination.
Have the relay up and working now but getting some unusual errors when trying to use a Bluetooth app from my phone. Have it resolved now with some help from the Forum.
Unfortunately while I was trying to figure out how, while running on battery power, to send a high signal output via pin 12 to a MOSFET module, so that I could turn on a 12V supply to a 5V regulator module connected to the VU pin with the intention of only running from the 12V supply for a few minutes to keep the regulator from getting too hot, I crossed something up and the dreaded blue smoke came from the board. I think I burnt the onboard regulator or something.
I've got a new one on order :-) It'll be better managed this time around, I promise.
