 ## RAK815
 
 TODO:
-This board has a TCXO, which is uncommon. For better RF performance it should be enabled P0.05 (RF95_TCXO) high. And then tell the RF95 to use it.
+* P0.23 is for PABOOST? see page 2 in RAK813 sechematic  P0.22 is for HF_RF_CPS?  Look up datasheet for PE4259  Until this is fixed I bet the range is quite poor.  DIO2 is not 
+controlling PABOOST on this board!
+* i2c gps
+* BLE link
+* measure power draw
