EFM8™ Sleepy Bee High Flash Capacity 8-bit MCU Starter Kit


The Silicon Labs EFM8 Sleepy Bee Starter Kit is an excellent starting point to evaluate and develop very low power applications on the EFM8 Sleepy Bee MCUs. These energy-friendly EFM8 MCUs are based on the popular 8051 core and are ideal for IoT systems processing data that comes from port I/O or sensor inputs. The SLSTK2011A high flash capacity starter kit can be used to evaluate EFM8SB2  set of devices. The kit is enabled with Advanced Energy Monitor (AEM) that can be used in conjunction with the Energy Profiler tool in Simplicity Studio for real-time current and voltage monitoring.

This kit includes the EFM8SB20F64G-A-QFN32 MCU with 64 kB of flash and a maximum operating frequency of 25 MHz. The EFM8BB22F16G-A-QFN28 MCU also includes 4352 B of RAM.

The Sleepy Bee Starter Kit Includes

  • Integrated debugger
  • Si7021 humidity and temperature sensor
  • LCD display
  • Pushbuttons
  • 32 kHz crystal for Real Time Clock (RTC) operation
  • Single-color LED
  • 1 mini USB cable
