The next pictures shows how to add L1, R1, L2 and R2 to the 2nd revisions of the Bittboy. Thanks to WenTao for this.

1) Placing the buttons

2) Identify the connectors

Circuit pins (no resistor boost is required for all keys, use the internal resistor boost):

L1 to SPI IC pin 1\ R1 to SPI IC pin 2\ L2 to SPI IC pin 6\ R2 to SPI IC pin 5\ l-r-2

3) Trim the case

4) Final product
