The SparkFun ESP32 Thing is a great choice for getting started with IoT based projects, it comes with an on-board WiFi and Bluetooth.
The Medusa ecosystem from Edwin Robotics is an easy to use, plug and play platform that allows beginners, hobbyists and enthusiasts to go from ideation to prototyping without the need for cumbersome connections on the breadboard or point to point soldering on a protoboard. This is possible using polarized connectors which fit only way, like the USB (except type-C). Resulting in an error-free connection.
The Medusa Head for SparkFun ESP32 Thing breaks out 15 of the 26 pins I/O. In addition to this, we have also provided four i2c ports providing ample ports for connecting i2c based interfaces.
Note: Sparkfun ESP32 Thing is included with base board
