SparkFun Thing Plus - ESP32-C6

Packed with cutting-edge technology and housed in a compact, user-friendly footprint, the SparkFun ESP32-C6 Thing Plus empowers your wireless creations like never before. At its heart lies the powerful ESP32-C6 WROOM-1-N16 module from Espressif, boasting a RISC-V single-core processor, more than enough flash memory, and a diverse selection of wireless connectivity options. Dive into the realms of 2.4 GHz WiFi 6, Bluetooth® 5.3, Zigbee and Thread (802.15.4), unlocking a world of possibilities for your projects.

The SparkFun ESP32-C6 Thing Plus is equipped with multiple features that accentuate the boards potential. The microSD card slot lets you expand your project's capabilities, while the Qwiic connector seamlessly integrates the Thing Plus into SparkFun's vast ecosystem of sensors, actuators, and more.

This development board also includes a LiPo battery charger and fuel gauge, an addressable LED, and more. The Thing Plus footprint is Feather-compatible and breaks out all of the ESP32-C6's 23 GPIO pins to 0.1in.-spaced PTH headers. For primary power and programming, the board is also equipped with a USB-C connector and a 2-pin JST connector for a LiPo battery.

The ESP32-C6 includes a wide range of peripheral options including SPI, UART, LPUART, I2C, I2S, LED PWM, USB Serial/JTAG controller, ADC and more. Many of these peripherals can be mapped to any GPIO pin though some are tied to specific pins.

Elevate your wireless projects with the SparkFun ESP32-C6 Thing Plus. Its intuitive design, powerful features, and seamless connectivity await.


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-C6 Product Help and Resources

Core Skill: Programming

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.

3 Programming

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.
See all skill levels


Core Skill: Electrical Prototyping

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.

2 Electrical Prototyping

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.
