## Description

The Feather M0 RFM69HCW Packet Radio (433 MHz) combines the ATSAMD21G18 ARM Cortex M0+ processor with an SX1231-based RFM69HCW radio transceiver for wireless data communication at 433 MHz. It includes built-in USB, LiPo battery charging, and the full Feather M0 pin set in a compact, portable form factor. The RFM69HCW radio is ideal for small data packet transmission where you need greater range than 2.4 GHz technologies like Bluetooth, Wi-Fi, or ZigBee. With up to 100 mW output power, AES-128 encryption, and multipoint networking support, it suits a wide range of wireless sensor and control applications. Key Features ATSAMD21G18 Processor – ARM Cortex M0+ running at 48 MHz, 3.3V logic 256 KB Flash + 32 KB RAM – 8× more flash and 16× more RAM than ATmega328/32u4 RFM69HCW 433 MHz Radio – SX1231-based packet radio with SPI interface +13 to +20 dBm Output – Up to 100 mW transmit power, selectable in software ~350 m Range – Depending on obstructions, antenna, and power settings AES-128 Encryption – Hardware-accelerated encrypted packet engine Multipoint Networking – Individual node addresses for creating wireless networks Native USB – Built-in USB-to-Serial for programming and debugging, no FTDI chip needed 20 GPIO Pins – Hardware Serial, I2C, and SPI; 8× PWM, 10× analogue inputs, 1× analogue output LiPo Battery Support – JST connector with built-in 100 mA charger, battery voltage monitoring via analogue pin Compact Design – 51 mm × 23 mm × 8 mm, weighing 5.8 g Also Available Feather M0 RFM69HCW 868/915 MHz – Same radio at 868/915 MHz Feather M0 RFM95 LoRa 900 MHz – Long-range LoRa radio Feather M0 RFM96 LoRa 433 MHz – Long-range LoRa at 433 MHz Feather M0 Express – CircuitPython with 2 MB flash Feather M0 Basic Proto – Prototyping area Feather M0 Adalogger – MicroSD data logging Feather M0 Bluefruit LE – Bluetooth Low Energy Feather M0 WiFi – ATWINC1500 Wi-Fi Ideal For Wireless sensor networks and remote monitoring Battery-powered radio telemetry Point-to-point and multipoint data links IoT projects requiring sub-GHz range Package Contents 1× Feather M0 RFM69HCW 433 MHz 1× Header pin set Note: A wire antenna must be soldered to the board (any solid or stranded core wire will work).
