UG126: EFM8LB1-SLSTK2030A User's
Guide

The EFM8LB1-SLSTK2030A is an excellent starting point to get
familiar with the EFM8 Laser Bee microcontrollers.

The kit contains sensors and peripherals demonstrating some of the MCU's many capa-
bilities. The kit can also serve as a starting point for application development.

The kit includes the following:

KEY FEATURES

• EFM8LB12F64E MCU with 64 kB Flash

and 4 kB RAM.

• 20-pin expansion header.
• Power sources include USB and CR2032

battery.

• 2 user buttons, 1 tri-color LED.
• 8-direction joystick.
• Ultra low power 128x128 pixel Memory-

LCD.

• EFM8LB1 Laser Bee Starter Kit Board
• 1 x CR2032 battery

• Getting Started card
• 1 x mini USB cable
