The SparkFun IoT RedBoard is an ESP32 Development Board that includes everything but the kitchen sink! 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. The IoT RedBoard can target a wide variety of applications, ranging from low-power sensor networks to the most demanding tasks, such as voice encoding, music streaming, and MP3 decoding. The IoT ReadBoard also utilizes our handy Qwiic Connect System which means no soldering or shields are required to connect it to the rest of your system!
The USB-to-serial is achieved with a USB-C connector with through hole anchoring and the ubiquitous CH340G requiring fewer driver installs. We've included 3.3V voltage translation and a Qwiic connector to the edge of the board to allow for quick and seamless connection to our ever-growing line of I2C based Qwiic products. The board even includes a microSD socket if your application requires you to log and save data to a memory card. For remote power, we have included a 2-pin JST connector to attach a single cell, LiPo battery. There's also a built-in LiPo charge IC (MCP73831) and fuel gauge (MAX17048).
The operating system is freeRTOS with LwIP; TLS 1.2 with hardware acceleration is built in as well. Secure (encrypted) over the air (OTA) upgrade is also supported, so that users can upgrade their products even after their release, at minimum cost and effort.
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.
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: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.

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.

Grabbed this board for a research project and it has snowballed into a conference talk. I will likely be buying these in bulk for handouts throughout the year. Great work, SparkFun!!
It was very easy to setup, using the examples on the SparkFun web site. I'd like to see a future version with more Audio I/O capabilities (ADC, DAC, support variable audio sample rates and bit depth, 3.5mm jacks, etc.) Thanks for a great product!
