The PG22 Dev Kit is a low cost, small form factor prototype and development platform for the EFM32PG22 microcontroller. The board is a small and cost-effective, feature-rich, prototype and development platform based on the EFM32™ microcontroller. The PG22 Dev Kit is an ideal platform for developing energy-friendly electronic devices. A built-in SEGGER J-Link debugger ensures easy debugging through the USB Micro-B connector. Most of the EFM32PG22 I/Os are routed to breakout pads on the sides of the board making it easy to expand on the board and evaluate the EFM32PG22's features with custom hardware.
