The FreeSK8 NRF52 BLE Module is an NRF52840 Bluetooth & NRF Receiver, designed to be a drop-in upgrade for existing NRF51 based dongles.

This module functions as a Bluetooth connection + NRF remote receiver, compatible with remotes such as the FreeSK8 Remote or Trampa Wand. 

The NRF52 BLE Module does not have any integrated logging features, look to the Robogotchi for such witchcraft. 

There are three variants available:

  • NRF52-S (Standard Trace Antenna - BT840 Module)
  • NRF52-XR (Extended Range Trace Antenna - BT840F Module)
  • NRF52-EXT (Extended Range External Patch Antenna - BT840E Module)

The S model uses a standard antenna configuration. In most enclosures & environments, this variant should be sufficient. It is not recommended for use inside closed CF/Metal enclosures. 

The XR & EXT variants provide additional options for interference heavy environments or more RF-resistant mounting solutions. The NRF52-EXT variant includes an external directional patch antenna. 

All modules come with an 7-pin UART Cable. 8-pin PH JST connector included. 

This is an initial hardware revision release, while based on well-proven technologies, should be considered a beta release and tested/used with appropriate respect & caution. If you have any questions, please do not hesitate to reach out to support.
