Dragino LoRa/GPS HAT Board for Raspberry Pi Sells for $32

There are several ways to play with LoRaWAN protocol on the Raspberry Pi including RisingHF Discovery kit or Cooking Hacks LoRa Shield for Raspberry Pi, but the latter requires you to spend close to $100 just for the shield, the complete Lora discovery kit costs close to $400. Dragino Tech LoRa/GPS HAT board should be a more cost effective way to get started with LoRa on Raspberry Pi, as it sells for $32 + shipping on Tindie. Dragino LoRa/GPS HAT specifications: Connectivity LoRa Semtech SX1276/SX1278 transceiver @ 433/868, or 915 MHz (Country dependent, pre-configured in the factory) 168 dB maximum link budget. +20 dBm – 100 mW constant RF output vs. +14 dBm high efficiency PA.

RisingHF IoT Discovery is a LoRaWAN Evaluation Kit for Raspberry Pi

There are many current and upcoming long range low power wireless protocols for the IoT, but this morning I learned that South Korea launched a LoRa network (aka LoRaWAN), after another launch in the Netherlands earlier this year. While there are also some LoRa hobbyist kits such as LoraONE and LoPy being worked on, I decided to look on Aliexpress, but only got two products were listed: a LoRaWAN temperature and humidity sensor, and a LoraWAN USB modem. Both of them are made by a company called RisingHF. Among the products offered by the company, there’s a potentially interesting development kit called RisingHF IoT Discovery with the following components: 1x Raspberry Pi board 1x RHF0M301 LoRa Gateway based on Semtech SX1301 1x RHF4T002 adapter for Raspberry Pi and RHF0M301 1x RHF3M076 LoRaWAN USB AT Modem End point to connect to computer. It operates at 434MHz, 470MHz,868MHz, and 915MHz 3x RHF76-052 […]
