The Spresense is one of the most important building blocks for BCB's edge devices, it is small enough to build powerful things in small packages. The open source designs can help you to create your own custom and smaller board if you are planning to produce huge amounts of devices. After reading all the related material you will realize that I really like this board because it is almost what I ever wanted, but be aware that this market is evolving rapidly.

The Microchip RN2903 Module
  • LoRaWAN Compliant, Full Stack firmware

  • Type A and C compliant

  • LoRa and FSK modulation (255/64 bytes)

  • Easy to integrate with MCUs (UART)

  • Easy to configure (text commands, radio and mac)

  • Configurable output power

  • Secure Encryption

  • Low power consumption by inherited LoRa nature

  • Long Range, 10Km (tested) even more by specs

  • Environment friendly.

Intelligence and power without communication worth nothing, that's why LoRa is so important for Big Cat Brother. I've been working with these modules (I was supposed to be testing things from Semtech but the pandemic forced me to stop some collaborations for precaution) and they delivered the LoRa promises, all of them, from range to battery durability. The good thing about this module is the freedom you have in terms of configuration. You can easily choose to use the LoRaWAN standard or use the module just as a LoRa radio, BCB uses both schemes, so it is perfect for my needs. I tested these modules in the real environment and they performed superbly. Always keep in mind that Battery life will depend on your needs to communicate things, if you need to send or receive messages all the time you cannot expect this device running for years on a single battery charge.
