FireBeetle is a product series of small development boards developed by DFRobot. It contains various chipboards and expansion boards that can be used alone or in combination. The same as Arduino M0, FireBeetle 2 M0 also adopts the high-performance low-power chip ATSAMD21G18 ARM Cortex M0+. With up to 48MHz frequency, it offers 32kb RAM and 256kb Flash, which is 8 times and 16 times of Atmega328 respectively. Designed with 16MB SPI Flash and a built-in 12MB flash drive, FireBeetle 2 M0 simplifies the data interaction between the user's desktop system and the board and supports SPI Flash-based easy flash database. Besides, the built-in SPI Flash-based word model allows users to directly display multi-language words, such as Chinese, British, Japanese, and Korean. Firebeetle 2 Board-M0 (V1.0) adopts a convenient Type-C port and a more comfortable horizontal switch. The onboard WS2812 RGB indicator and FPC make the display much easier to use. Note: FireBeetle 2 and FireBeetle pins and sizes are not compatible, and neither are the expansion boards.
