Microcontrollers
Arduino Uno is a microcontroller board based on the ATmega328P. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator (CSTCE16M0V53-R0), a USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.. You can tinker with your Uno without worrying too much about doing something wrong, worst case scenario you can replace the chip for a few dollars and start over again.
"Uno" means one in Italian and was chosen to mark the release of Arduino Software (IDE) 1.0. The Uno board and version 1.0 of Arduino Software (IDE) were the reference versions of Arduino, now evolved to newer releases. The Uno board is the first in a series of USB Arduino boards, and the reference model for the Arduino platform; for an extensive list of current, past or outdated boards see the Arduino index of boards.
The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3.x). It has more or less the same functionality of the Arduino Duemilanove, but in a different package. It lacks only a DC power jack, and works with a Mini-B USB cable instead of a standard one.
The Nano ESP32, a powerful addition to the Arduino ecosystem that brings the popular ESP32-S3 to the world of Arduino and MicroPython programming. Whether you're a beginner stepping into the world of IoT or MicroPython, or an advanced user looking to incorporate it into your next product, the Nano ESP32 is the perfect choice. It covers all your needs to kick-start your IoT or MicroPython project with ease.

There are no more excuses to delay your exploration of IoT and MicroPython. The Nano ESP32 provides everything you need to start creating and discovering the endless possibilities.
The Teensy is a complete USB-based microcontroller development system, in a very small footprint, capable of implementing many types of projects. All programming is done via the USB port. The Teensy is available with header pins, for direct no-soldering-required use on a breadboard, which can also be run from the +5 volt from the USB cable. Standard Teensy boards come with solder pads. Either way, all Teensy boards come fully assembled and tested, so no surface mount soldering is needed.
Key Features:
- Compatible with Arduino Software & Libraries
- USB can be any type of device
- Single pushbutton programming
- Easy to use Teensy Loader application
- Free software development tools
- Works with Mac OS X, Linux & Windows
- Tiny size, perfect for many projects
- Available with pins for solderless breadboard
FPGAs
A field-programmable gate array (FPGA) is a configurable integrated circuit that can be programmed using an HDL (Hardware Description Language). FPGAs are a subset of logic devices referred to as programmable logic devices (PLDs). They consist of a grid-connected array of programmable logic blocks that can be configured "in the field" to interconnect with other logic blocks to perform various digital functions.
Alchitry Mojo is a development board based around the Xilinx Spartan 6 FPGA and the ATMega32U4 8-bit microcontroller. This device is the board used in the book "Learning FPGAs" by Justin Rajewski. It used by interns in the program to develop the IO devices for the calculator project.
The Mojo has an Arduino-compatible microcontroller whose main function is to program the FPGA over USB. However, once the FPGA is programmed, the microcontroller can be used as an ADC (eight analog inputs are broken out) and a USB-to-serial interface for your FPGA designs. Beyond the other bare necessities such as a 50 MHz oscillator, the Mojo features eight LEDs and a button (commonly used as a reset).
The I/O (a total of 84 digital I/O pins) on the Mojo is all at 3.3 V and is not 5 V tolerant. A level shifter was used at the junction between the FPGA and the 8085 microprocessor. Power can be supplied via the USB port, the barrel jack, the two holes, or the RAW input on the large headers. The supplied power should be between 4.8 V–12 V, with 5 V being the recommended voltage. You can connect an external power supply and the USB port at the same time, as the USB port is protected by a diode.
This device has been discontinued by the manufacturer and its use is deprecated in the program.
