What can You do With an Adafruit Huzzah32 ESP32?
The Huzzah32 ESP32 is a fantastic development board. There's Feather Arduino IDE (Integrated Development Environment) support. Outfitted with GPIO galore, the Huzzah32 Feather can interface with a bevy of different peripherals. And with Bluetooth as well as Wi-Fi support, the Huzzah32 is ideal for Internet of Things (IoT) applications.
For instance, it's been used to power an artificial intelligence (AI) freezer monitor that utilizes machine learning to provide early equipment failure warnings. And it's been crammed into a mini MIDI controller for music-making on the go. Essentially, the Huzzah32 is a good option for any scenario where you need an energy-efficient microcontroller for embedded applications.
Should You Use an Adafruit Huzzah32 Feather - Who is the Adafruit Huzzah32 for?
The Adafruit Feather Huzzah32 is best for developers and programmers. Since all of Adafruit's Featherwings function flawlessly under the Arduino IDE, different inputs/outputs (I/O) such as SPI and I2C work perfectly. However, it's not as well-documented as, say, an Arduino microcontroller. As such, the Huzzah32 is better suited for intermediate and advanced applications rather than beginner-friendly projects.
Still, it's a solid microcontroller for many makers. If you need ample I/O and great connectivity on a budget, the Adafruit Huzzah32 is a spectacular choice. You can build anything from simple IoT projects to complex creations with ease. There's even battery connectivity for portable projects.
The Competition - MCUs to Consider Instead of the Huzzah32
If you need an ESP8266-based microcontroller, the Huzzah8266 is a good option. The SparkFun ESP32 Thing is an excellent Espressif ESP32 board that touts Wi-Fi, Bluetooth Low Energy, and around 30 I/O pins.
DFRobot's Firebeetle is an ESP32 IoT MCU with Wi-Fi, Bluetooth, dual power supply support, and Lipo battery charging capabilities. For ESP32 in a smaller form factor, the Beetle ESP32 is a tiny yet powerful ESP32 microcontroller that has good I/O for its size including four analog ports, four digital ports, I2C, and UART.
Adafruit ESP32 Huzzah32 Feather - Final Thoughts
Overall, the ESP32 Huzzah32 Feather is a good, cheap Espressif ESP32-based microcontroller. There's Arduino IDE compatibility alongside ample inputs and outputs for an MCU that can handle tons of different embedded applications. From Internet of Things and smart home projects to music-making, the Huzzah32 is an incredible MCU. While it's not the most beginner-friendly board, it's a terrific bit of kit to graduate to once you've mastered beginner-friendly microcontrollers.
