+- add bus switch instead of common power rail for pull-up resistors
+- replace MAX232 RS-232 transceiver with 3.3V capable and enable pin alternative
+- add diodes on xV voltage regulator output to prevent voltage regulator to sink current
+- add transistor to disable completely 12V voltages regulator, allowing it to got to 0V instead of 5V)
