Adafruit 0.56" 4-Digit 7-Segment Display with I2C Backpack - Red STEMMA QT / qwiic Category_Arduino/LilyPad Arduino you can order the carrier

you can order the carrier board without any sensor and solder one in yourself

This is a full Python three implementation created specifically for small embedded microcontrollers

it can preform very well even in dim environments

The SparkFun FTDI Basic Breakout was designed to decrease the cost of Arduino development and increase ease of use (the auto-reset feature rocks

A fun way to make a small display is to use an 8x8 matrix or a 4 digit 7 segment display . Matrices like these are 'multiplexed' so to control all the seven segment LEDs you need 14 pins. That's a lot of pins, and there are driver chips like the MAX7219 that can control a matrix for you but there's a lot of wiring to set up and they take up a ton of space. Here at Adafruit we feel your pain! After all,
