3.6.1 Breakout Pads

34 breakout pads are provided and allow connection of external peripherals. The breakout pads are arranged in two rows and contain a
number of I/O pins that can be used with most of the EFM8BB52 Busy Bee's features. Additionally, the VMCU (main board power rail),
3V3 (LDO regulator output), and 5V power rails are also exposed on the pads.
The pin-routing on the Busy Bee is flexible, so most peripherals can be routed to any pin on port 1 or 2. However, pins may be shared
between the breakout pads and other functions on the BB52 Explorer Kit. The figure in section 3.6 Connectors includes an overview of
the breakout pads and functionality that is shared with the kit.
