LoRa with the Raspberry Pi Pico Fun with MicroPython

摘要

The Raspberry Pi Pico (Figure 1) is a new microcontroller board, featuring the RP2040. This chip is designed and developed in-house by the Raspberry Pi Foundation and therefore it is their first silicon, After seeing all the news around it-and after hearing about some of the doubts and fascination with it- I figured it was time to get some projects started, The board offers no Wi-Fi but can be run on a set of batteries for portable applications, so why not combine the Raspberry Pi Pico with a LoRa modem? The HOPERF RFM95 (Figure 2) is a well-priced and widely supported module that has been used in former Elektor projects, like My First LoRaWAN [1], While in this article an STM32 BluePill module was used, this time we will go with the Raspberry Pi Pico.
