Adafruit Feather M0 RFM69HCW Packet Radio - 433MHz
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
