# 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"


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.
10 QT PY RGB LED Die Adafruit QT PY and a 3x3 matrix of LEDs, or 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 / 5v Power Supply Same as the above one but it's a 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 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.
