NEW PRODUCTS: Radio Transceiver Breakouts – RFM69HCW 900 MHz or 433 MHz / LoRa RFM95W – 900 MHz or 433MHz

“You see, wire telegraph is a kind of a very, very long cat. You pull his tail in New York and his head is meowing in Los Angeles. Do you understand this? And radio operates exactly the same way: you send signals here, they receive them there. The only difference is that there is no cat.”

Sending data over long distances is like magic, and now you can be a magician with this range of powerful and easy-to-use radio modules. Sure, sometimes you want to talk to a computer (a good time to use WiFi) or perhaps communicate with a Phone (choose Bluetooth Low Energy!) but what if you want to send data very far? Most WiFi, Bluetooth, Zigbee and other wireless chipsets use 2.4GHz, which is great for high speed transfers. If you aren’t so concerned about streaming a video, you can use a lower license-free frequency such as 433 or 900 MHz. You can’t send data as fast but you can send data a lot farther.’

RFM69HCW Transceiver Radio Breakouts –

These are +20dBm FSK packet radios that have a lot of nice extras in them such as encryption and auto-retransmit. They can go at least 500 meters line of sight using simple wire antennas, probably up to 5Km with directional antennas and settings tweakings

• SX1231 based module with SPI interface
• +13 to +20 dBm up to 100 mW Power Output Capability (power output selectable in software)
• 50mA (+13 dBm) to 150mA (+20dBm) current draw for transmissions, ~30mA during active radio listening.
• Range of approx. 500 meters, depending on obstructions, frequency, antenna and power output
• Create multipoint networks with individual node addresses
• Encrypted packet engine with AES-128
• Packet radio with ready-to-go Arduino libraries
• Uses the amateur or license-free ISM band (ITU “Europe” license-free ISM or ITU “American” amateur with limitations)
• Use a simple wire antenna or spot for uFL or SMA radio connector

Available in both 900MHz  & 433 MHz

RFM95W LoRa Radio Transceiver Breakouts –

These are +20dBm LoRa packet radios that have a special radio modulation that is not compatible with the RFM69s but can go much much farther. They can easily go 2 Km line of sight using simple wire antennas, or up to 20Km with directional antennas and settings tweakings

• Packet radio with ready-to-go Arduino libraries
• Uses the license-free ISM band: “European ISM” @ 868MHz or “American ISM” @ 915MHz
• Use a simple wire antenna or spot for uFL or SMA radio connector
• SX1276 LoRa® based module with SPI interface
• +5 to +20 dBm up to 100 mW Power Output Capability (power output selectable in software)
• ~100mA peak during +20dBm transmit, ~30mA during active radio listening.
• Range of approx. 2Km, depending on obstructions, frequency, antenna and power output

Available in both 900 MHz & 433 MHz
