Mesh Node 5262M is a module based on the nRF52840 and SX1262, supporting both Bluetooth and LoRa communication modes. It offers a rich set of pins and interfaces, featuring a 1.27mm pitch stamp hole design, making it compact and easy to integrate into your PCB. Having powerful long-distance communication capabilities, scalability, and low power design, which make it excellent in a wide range of application scenarios such as smart cities, agricultural monitoring, logistics tracking, etc. It can be programmed via the Arduino IDE, PlatformIO, or MicroPython. You can directly use it for LoRa/LoRaWAN development with Heltec nRF52 framework and libraries , as well as to run some open source projects like Meshtastic.

FAQ
About SPI, I2C, UART, QPSI, I2S, PDM, QDEC: Each IO pin is preconfigured with IO_MUX functionality, which means you can use any GPIO as peripheral pins. You just need to define these pins in your SDK. However, it’s important to note that once a pin is used, it may affect other functions associated with that pin.
