## Description

The Feather 32u4 RFM69HCW Packet Radio (433 MHz) combines an ATmega32u4 microcontroller with an SX1231-based packet radio transceiver operating at 433 MHz, USB connectivity, and LiPo battery charging. It offers longer range than 2.4 GHz protocols (Bluetooth, Wi-Fi, ZigBee) with more flexibility than BLE, making it ideal for wireless sensor networks and remote control applications. The 433 MHz band is available as a license-free ISM band in many regions (ITU Region 1) and as an amateur radio band in others. Check your local regulations for permitted use. Key Features ATmega32u4 @ 8 MHz – 3.3V logic, 32KB flash, 2KB RAM Native USB – Built-in USB bootloader, serial debugging, and HID device support RFM69HCW Radio (SX1231) – 433 MHz packet radio with SPI interface +13 to +20 dBm Output – Up to 100 mW selectable in software AES-128 Encryption – Built-in encrypted packet engine ~350 m Range – Depending on obstructions, frequency, antenna, and power output Multipoint Networking – Individual node addressing for creating networks 20 GPIO Pins – Including 10 analogue inputs and 8 PWM outputs Hardware Serial, I2C & SPI – Full peripheral support Built-in LiPo Charger – 100 mA charging with status indicator LED Battery Monitoring – Battery voltage routed to an analogue pin via divider 3.3V Regulator – 500 mA peak current output Specifications Dimensions – 51 × 23 × 8 mm (without headers) Weight – 5.5 g Frequency – 433 MHz Mounting – 4 mounting holes Also Available Feather 32u4 RFM69HCW Packet Radio (868/915 MHz) Feather 32u4 RFM96 LoRa Radio (433 MHz) – Much longer range with LoRa modulation Feather 32u4 RFM95 LoRa Radio (868/915 MHz) Feather 32u4 Bluefruit LE – With Bluetooth Low Energy Feather 32u4 Adalogger – With MicroSD card holder Ideal For Wireless sensor networks with sub-GHz radio Remote control and telemetry systems Point-to-point and multipoint packet radio links Encrypted wireless communication at 433 MHz Package Contents 1× Assembled and tested Feather 32u4 RFM69HCW (433 MHz) 1× Header set Note: A wire antenna must be soldered on (any solid or stranded core wire is fine).
