We have discovered that XJT mini modules are using a pin that we did not anticipate for use in our module bay. It appears that the XJT mini module is the only module on the market that uses this pin.
Due to a hardware incompatibility between the XJT mini module and the Tango 2 (V2 and up) boards, the Tango 2 will NOT be able to support the XJT mini module.
After-market mod to add a module bay to your Tango 2. Sticks to the back of your Tango 2 and plugs into the receptacle board of your Tango 2.
Warning: The batch 1 of Tango 2 shipped without module bay capability. Please verify that there is a connector (in pictures above) before purchasing this add-on. Upgrade PCB's are available!
Also, whenever opening up your Tango 2 in future, you will need to open the module bay and release the flex PCB from the socket.
