Overview

 

At the Feather 32u4's heart is at ATmega32u4 clocked at 8 MHz and at 3.3V logic, a chip setup we've had tons of experience with as it's the same as the Flora. This chip has 32K of flash and 2K of RAM, with built in USB so not only does it have a USB-to-Serial program & debug capability built in with no need for an FTDI-like chip, it can also act like a mouse, keyboard, USB MIDI device, etc. This chip is well supported in the Arduino IDE and can run just about every sensor/library out there.

To make it easy to use for portable projects, we added a connector for any of our 3.7V Lithium polymer batteries and built in battery charging. You don't need a battery, it will run just fine straight from the micro USB connector. But, if you do have a battery, you can take it on the go, then plug in the USB to recharge. The Feather will automatically switch over to USB power when its available. We also tied the battery thru a divider to an analog pin, so you can measure and monitor the battery voltage to detect when you need a recharge.

Excellent Handbook
Format: Paperback
What got my interest in this book is the author. He's well-known as a leader in the LangChain world. And his book did not disappoint. It goes through the whole life cycle of development and there is a lot useful insights. If you are looking to build real-world genAI/agentic apps, then this book is certainly a great choice.

The most complete set of study aids I have ever used!
Format: Paperback
I have never encountered a set of books this well done. Everything in each book is written to help you understand the CompTIA A+ certification. It addresses the topics with a great overview and then specifics. It starts with a test to establish your level of experience. It is written in a way that lends itself to moving around to different topics to keep things fresh. There are online flash cards aplenty! There are also a ton of practice questions both in the books and online. These books increased my confidence, not just because the exams helped me learn that I knew more than I thought, but because I feel confident that I can learn the rest! Thank you for the great job!
