Hardware

We currently support devices that use the ESP32 and the nRF52 microcontrollers. Both of these offer low power consumption and long battery life, but each come with their own advantages:

ESP32

The following ESP32 devices are supported:

caution

Supported but not encouraged:

  • Lilygo TTGO T-Beam - version 0.7 -- Very old, no power management chip, difficulty with GPS module and is frequently confused with other devices.

Advantages:

  • Strong hardware/software support, as these devices have been on the market for a longer period of time
  • Wi-Fi capable, with full web interface support
  • Numerous 3D printed case designs are available
  • Range Test module is supported

Disadvantages:

  • Devices do not use Bluetooth 5.0 (BLE), as such may may draw more power

nRF52

The following nRF52 devices are currently supported:

Advantages:

  • Smaller, more compact designs are available
  • Draws 90-95% less power compared to ESP32
  • Very low Bluetooth power usage due to Bluetooth 5.0 (BLE)
  • Strong manufacturer documentation for RAK Wireless products

Disadvantages:

  • No Wi-Fi without additional hardware, the Web interface can only be used via the Serial connection option.
  • Newer hardware, as such less software-side support.
  • Currently, cannot be used with the Range Test module.
  • Fewer 3D printed case options.
