Adafruit Perma-Proto Half-sized Breadboard PCB - Single

Half-size solderable prototyping PCB laid out like a breadboard. Use after a breadboard works, not as an active module.

5mm LED Pack (50 PCS)

Pack of simple 5 mm LEDs in multiple colors. Use with suitable current limiting and GPIO or driver design.

Premium Female/Female Jumper Wires - 40 x 6

Female-to-female jumper leads for joining male header pins. Match gender and length before substituting.

Premium Female/Male 'Extension' Jumper Wires - 40 x 6 (150mm)

Female-to-male jumper leads for extending a header connection. Similar length to the female-to-female pack, but different end gender.

Flora RGB Smart NeoPixel version 2 - Pack of 4

Addressable RGB NeoPixel boards. They need power, ground and a timing-sensitive data signal, not just LED current limiting.

Arduino Leonardo Microcontroller

ATmega32u4 controller board with built-in USB. Treat as a complete controller, not a connector or accessory.

TMP36 Analog Temperature Sensor

Analog Celsius temperature sensor. Needs an analog input and voltage conversion in firmware.

TIP120 Darlington Transistor (3-pack)

NPN Darlington transistor pack for switching heavier loads. It is a component-level switch, not a motor-driver module.

SparkFun DeadOn RTC Breakout - DS3234

DS3234 real-time-clock breakout with SPI interface. Use when the design needs a clock source.

Micro SD(TF) Storage Board

MicroSD storage breakout. Use when the design needs removable storage through a controller interface.

RTC Module - Super Capacitor

Super-capacitor RTC module intended for Raspberry Pi-style timekeeping, with Arduino use also described by Seeed.
