# Project Info
01 Breadboard Power Supply Module 3.3v or 5v selectable. 3 different inputs (barrel jack, miniUSB, screw terminal block).
02 5-Button Switch Module 5-button terminated switch module for breadboards.
03 Real Time Clock (RTC) Module PCF8523 RTC chip with battery backup, for breadboards.
04 Buzzer-Type Speaker Module Small, unobtrusive, adjustable, amplified buzzer speaker designed for breadboard use.
05 LED Dot Matrix Module: Chicago Dice! Arduino Nano microcontroller-based game, with expansion connector.

QuadRupler 2.4" and QuinTupler 3.5"

Powered expansion boards for Adafruit Feather microcontrollers like the Adafruit Feather M4 Express.

Each PCB permits 3 or 4 FeatherWings to attach to a 2.4" or a 3.5" FeatherWing TFT-touchscreen display.

07 3v3 to 5v Level Shifter Breadboard-connect your new 3.3v peripherals to older 5v microcontrollers like Arduino Uno or Arduino Nano.
08 ItsyBitsy Roller Needs rework) Adafruit ItsyBitsy M4 Express or ItsyBitsy RP2040 based Neopixel gaming board.
09 Bakk Tracker Adafruit GPS used to track your way back to your starting point.

Project A: Adafruit QT-PY and a 3x3 matrix of LEDs.

Project B:  Adafruit QT-PY and two 3x3 matrices of RGB Neopixel LEDs.

11 Neopixel 3x3 Array Neopixel 3 x 3 array board to add to your projects.
12 Breadboard SMT Power Supply 3.3v or 5v selectable. 2 different inputs: barrel jack or miniUSB.
13 SMT 3v3 3A / 5v 5A Power Supply Same as the above one but it's a higher current PCB that you can attach to your breadboard or quickly solder to your project bd.
14 Neopixel 5x5 Array Neopixel 5 x 5 array board to add to your projects.
15 Nano Neo Arduino Nano-based RGB Neopixel board with 3 add-on boards: power supply, amplified buzzer and 5x5 Neopixel array.
16 Nano Neo Strands Arduino Nano-based driver board for up to 4 strands of Neopixel RGB LEDs.
17 QT-PY 8x8 RGB LED Dice Adafruit QT-PY driving two 8x8 RGB LED matrices.
18 Single-Multistep CPU Clock Module A PCB using Ben Eater's 1-500Hz CPU Clock design for both single-step and multi-step functions.
19 Variable CPU Clock Module A PCB using Ben Eater's  1-500Hz CPU Clock multi-step design.
23 Project 23: Weather Inside The Aduino Weather Inside app running on a small PCB.
24 Project 24: 9DoF An Adafruit Nine degrees of freedom orientation IMU, weather sensor and a 2.0" display.
25 Project 25: Accelerometer An Adafruit accelerometer, weather sensor and a 2.0" display.
