The Beetle RP2350 is a coin-sized development board designed for space-constrained embedded projects. Despite its compact 25 × 20.5 mm footprint, it offers a wide range of hardware features and low power consumption, enabling its use in portable devices such as retro computers, game consoles, lighting controllers, and electronic badges.
The RA0E1 Feather SoM is designed for ultra-low-power use cases. It features an Arm Cortex-M23 CPU core operating at up to 32 MHz with 64 KB of Flash memory. Its minimal power draw makes it suitable for battery-powered systems that require extended uptime. Standard Feather features are included, such as analog/digital GPIOs, I2C, SPI, UART, a LiPo battery connector, and USB Type-C for both power and programming.
