Adafruit WICED WiFi Feather – STM32F205 with Cypress WICED WiFi

Discontinued – you can grab Adafruit HUZZAH32 ESP32 Feather Board instead!

Say “Hi!” to the WICED Feather, perfect for your next Internet connected project, combining a powerful STM32F205 ARM Cortex M3 processor running at 120MHz and Cypress BCM43362 802.11b/g/n WiFi radio.

Feather is a new development board standard from Adafruit: thin, light, and designed for portability. The WICED Feather is our most powerful Feather yet, supporting secure TLS 1.2 connections, multiple GPIO, SPI, UART, I2C interfaces, and built-in hardware features like a real-time clock and LiPo battery charging.

• Compact size: 2.0″ x 0.9″ x 0.28″ (51mm x 23mm x 8mm)
• Lightweight: 5.7 grams
• STM32F205RG 120MHz ARM Cortex M3 MCU
• BCM43362 WiFi 802.11b/g/n radio
• 128KB SRAM and 1024KB flash memory total, with 16KB SRAM and 128KB flash for user code
• 16MBit (2MB) SPI flash for additional storage
• Built-in RTC with optional external battery
• Hardware SPI, I2C, UART (up to 3), PWM outputs (7 standard)
• Up to eight 12-bit ADC inputs and two 12-bit DAC outputs
• TLS 1.2 support for secure HTTPS and TCP servers
• Onboard LiPo battery charging and monitoring
• USB bootloader for easy programming via Arduino IDE

Comes fully assembled and tested, with included header pins suitable for solderless breadboards. LiPo battery and MicroUSB cable are not included.

Note: This developer edition board may have firmware updates. It requires STM32 compatible libraries, and many AVR-specific Arduino libraries won’t work.
