Ever since the IoT MCU RP2040 was announced by Raspberry, excitement was high. Finally, the first Pico breakout boards with the RP2040 MCU arrived and of course the first thing we did at RAK was to connect it to a LoRa® transceiver and add long range communication capabilities to the Pico.
SX1261, SX1262 and SX1268 sub-GHz radio transceivers are ideal for long range wireless applications. Both devices are designed for long battery life with just 4.2 mA of active receive current consumption. https://www.semtech.com/products/wireless-rf/lora-transceivers/sx1262
A large portion of the IoT network technology (LoRaWAN in particular) focuses on a centralized model, where there are end nodes and gateways.
There are many LoRa modules available out there on the market. And we can surely say that RAK4270 module is one of the most competitive ones.
While the WisBlock Core RAK4631 is built on the low power Nordic nRF52840 MCU and the low power LoRa® transceiver Semtech SX1262, having both of them active all the time is not ideal for battery-supplied solutions.
