  Receives from software serial, sends to hardware serial.
 
  The circuit:
- * RX is digital pin 2 (connect to TX of other device)
- * TX is digital pin 6 (connect to RX of other device)
+ * RX is digital pin 2 (P0_10) (connect to TX of other device)
+ * TX is digital pin 6 (P0_2) (connect to RX of other device)
 
  Note:
- Not all pins on the Elbear Ace-Uno support interrupts,
- so only the following can be used for RX:
- 2, 3, 4, 5, 8, 9
+ Not all pins on the Elbear Ace-Uno/Ace-Nano support interrupts,
+ so only the following can be used for RX: 2, 3, 4, 5, 8, 9
+ Elsomik board pins with interrupts: P0_8, P1_4, P1_5, P1_6, P1_9, P1_10, P1_15, P2_7
