DEV KIT WEEKLY: Silicon Labs BGM220 Bluetooth 5 Explorer Kit

November 13, 2020 Perry Cohen

This small form factor development and evaluation platform is designed around another, smaller form factor piece of hardware – the BGM220P Bluetooth Module, which rests up here at the top of the board.

Based on Silicon Labs’ EFR32BG22 SoC (Figure 1), the BGM220P itself is a full-featured, modern-day Bluetooth connectivity solution, with a 2 Megabit PHY and built-in antenna that support long-range Bluetooth 5 low energy connectivity and Bluetooth Mesh. It has a maximum power output of 8 dBm that helps deliver a robust and reliable RF communications link, RF shielding, and a top-notch receive sensitivity of -98.9 dBm.

Figure 1. Silicon Labs' EFR32BG22 BLE 5.2 system on chip is the basis of the BGM220P module on the BGM220 Bluetooth 5 Explorer Kit, and features an Arm Cortex-M33, radio subsystem controlled by an Arm Cortex-M0+, and a host of other peripherals.

The BGM220P is also certified worldwide (Figure 2).

Figure 2. The BGM220P builds on the  EFR32BG22 BLE 5.2 system on chip with an optimized set of peripherals in a package ready for volume integration and deployment.

All in all, this is a great, flexible way to get going with advanced Bluetooth tech, and here’s why. If you want a BGM220 Explorer Kit, you’re in luck because Silicon Labs sells them for just $9.99.
