-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:
-
-- [Lilygo TTGO T-Beam](/docs/hardware/supported/tbeam) - 1.1 (including M8N GPS and SX1262 LoRa variants)
-- [Lilygo TTGO Lora](/docs/hardware/supported/lora) - versions 1, 1.3, 2.0, 2.1-1.6
-- [Heltec LoRa 32 (V2)](/docs/hardware/supported/heltec)
-
-:::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](/docs/software/web) 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:
-
-- [Wisblock RAK4631](/docs/hardware/supported/wisBlock) (Modular system, requires wisBlock Base)
-- [Lilygo TTGO T-Echo](/docs/hardware/supported/techo)
-
-
-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.
