The RP2350 Feather is a powerful, battery-powered dev board in the Feather format, compatible with FeatherWings. It features 8MB of flash, a 22-pin HSTX output, Stemma QT, debug SWD, and an optional PSRAM spot. Powered by the RP2350 chip with dual M33 cores running at 150 MHz, it offers faster performance, hardware floating point, and 520KB of SRAM for more memory. It includes three PIO blocks, TrustZone secure boot, and the HSTX port for high-speed data transmission. Ideal for IoT, CircuitPython, and MicroPython projects.
Features:
- Dual ARM Cortex-M33 @ 150MHz with floating point unit
- 520KB SRAM and 8KB OTP memory
- Supports up to 16MB external Flash via QSPI
