GatePi is a low-power data transmission board with an onboard CH340 USB TO UART converter, 74HC125V Voltage-Level Translator.

LoRa is a new wireless technology that has only been in use for a few years. Its combination of long-range transmission capabilities and low-energy requirements makes it appealing for projects that need to be kept in a position where access to power or regular battery changes isn't possible (theoretically, up to several miles). The disadvantage of LoRa is that its data capacity is limited; it's best suited for brief, periodic broadcasts rather than real-time frequency. Receiving temperature updates from a distant sensor every few minutes, for example, would be possible with LoRa; but, streaming a video feed would be impossible.

LoRa now works on three distinct frequencies. 433MHz has been set aside for Asia. The allotted frequencies for Europe and the United States are 868MHz and 915MHz, respectively. The most common LoRa Modules are SX1268 and others. SX1262/68 Chips are used in the majority of the IoT LoRa projects mentioned here.

• Based on SEMTECH's SX1268 RF chip, the E22-400T22S1B is a wireless serial port module (UART).
• Based on SEMTECH's SX1262 RF chip, the E22-900T22S is a wireless serial port module (UART)

LoRa initiatives continue to spring up as the technology's appeal spreads beyond Europe to other continents. Here is a handful that struck our notice and demonstrates GatePi's possibilities.

SB Components has released a number of LoRa devices, including the Pico LoRa extension, the LoRa HAT for Raspberry Pi, the RangePi (Range-Pi "Plug and Play LoRaTM Dongle" based on Raspberry Pi RP2040), and now the GatePi 4-Channel Relay with LoRa Module based on RP2040.

GatePi Introduction 

 GatePi is a low-power data transmission board with an onboard CH340 USB TO UART converter, 74HC125V Voltage Level Translator, E22-400T22S/E22-900T22S SMA antenna connector that covers the 433/868/915 MHz frequency band, 4-Ch Relays, IPEX antenna connector, and LoRaTM Spread Spectrum Modulation technology with auto multi-level repeating. GatePi is a serial port data transmission device that can send data up to 5 kilometers.

GatePi is a smart LoRa Relay Board that may be used to operate industrial and household equipment from afar. The Remote Power Switch allows you to regulate the power of external devices or appliances from a distance. Controlling general gadgets, lights, irrigation systems, pumps, remote servers, towers, activating and disabling security systems, and access management of gates and doors are all examples of appliances.

The inbuilt LoRa module is used to communicate with the Remote Power Switch. Simply use a Micro-USB connection to upload the code, connect to your LoRa network, plug the Remote Power Switch into a power outlet, and plug your appliances into the Remote Power Switch.
