The new STM32F405 Feather that we designed runs CircuitPython at a blistering 168MHz – our fastest CircuitPython board ever! We put a STEMMA QT \/ Qwiic port on the end, so you can really easily plug and play I2C sensors.\u003c\/p\u003e\n\u003cp\u003eThis Feather has lots of goodies:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSTM32F405 Cortex M4 with FPU and 1MB Flash, 168MHz speed\u003c\/li\u003e\n\u003cli\u003e192KB RAM total - 128 KB RAM for general usage + 64 KB program-only\/cache RAM\u003c\/li\u003e\n\u003cli\u003e3.3V logic, but almost all pins are 5V compliant!\u003c\/li\u003e\n\u003cli\u003eUSB C power and data - our first USB C Feather!\u003c\/li\u003e\n\u003cli\u003eLiPo connector and charger\u003c\/li\u003e\n\u003cli\u003eSD socket on the bottom, connected to SDIO port\u003c\/li\u003e\n\u003cli\u003e2 MB SPI Flash chip\u003c\/li\u003e\n\u003cli\u003eBuilt in NeoPixel indicator\u003c\/li\u003e\n\u003cli\u003eI2C, UART, GPIO, ADCs, DACs\u003c\/li\u003e\n\u003cli\u003eQwiic\/STEMMA-QT connector for fast I2C connectivity\u003c\/li\u003e\n\u003cli\u003eWe use the built-in USB DFU bootloader to load firmware.

There's no auto-reset bootloader support yet so you have to pull the BOOT0 pin high and manually reset before uploading. That said, STM32 support is really good, and we were able to run just about every sketch we tried.\u003c\/li\u003e\n\u003cli\u003eMicroPython support is very solid but Adafruit does not provide MicroPython libraries for sensors!\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWe tested this in Arduino STM32duino with all our FeatherWings and only the RFM69\/RFM9x libraries did not work (they are very platform specific).
