Adafruit HUZZAH32 Developement Board – ESP32 Feather
This is the Adafruit Feather 32u4 LoRa Radio (RFM9x). We call these RadioFruits, our take on an microcontroller with a "Long Range (LoRa)" packet radio transceiver with built in USB and battery charging.
This is the Adafruit Feather M0 RFM96 LoRa Radio (433 MHz). We call these RadioFruits, our take on an microcontroller with a "Long Range (LoRa)" packet radio transceiver with built in USB and battery charging.
Adafruit Feather M0 Basic Proto - ATSAMD21 Cortex M0 has a free prototyping space on the board. Feather is a new development board series from Adafruit. As the name suggests, Feather boards are thin and light. Feather is designed to be a new standard for open source development platforms.
The product is an Adafruit Feather 32u4 Basic Proto development board, based on the Atmel ATmega32u4 microcontroller, as its name implies. It has high performance and is easy to program, and can operate up to 8MHz.
Adafruit Feather WICED is based on the Broadcom WICED (Wireless Internet Connectivity for Embedded Devices) platform and is equipped with the 120MHz ARM Cortex M2 processor STM32F205 processor. Maybe the best plaque for TCP / IP-based projects.
