these are my pin mappings (with lots of useful info from johnrb):
OrangeRx Stabilizer RX3S V2
PB0 8 AIL_IN PC0 14/A0 DELTA_SW PD0 0 AUX_SW (RXD)
PB1 9 ELE_IN (PWM) PC1 15/A1 AIL_GAIN PD1 1 AIL_SW (TXD)
PB2 10 RUD_IN (PWM) PC2 16/A2 ELE_GAIN PD2 2 ELE_SW
PB3 11 AUX_IN (MOSI/PWM) PC3 17/A3 RUD_GAIN PD3 3 RUD_SW (PWM)
PB4 12 VTAIL_SW (MISO) PC4 18/A4 (SDA) PD4 4 AILL_OUT
PB5 13 LED (SCK) PC5 19/A5 (SCL) PD5 5 ELE_OUT (PWM)
PB6 14 (XTAL1) PC6 (RESET) PD6 6 RUD_OUT (PWM)
PB7 15 (XTAL2) PD7 7 AILR_OUT
there are 6 dip switches.
the serial port is exposed, which is nice, but the chip probably does not have a bootloader. in any case, it's running at 3.3v so remember to reconfigure your usb-serial board for 3.3 operation if you want use the serial port..

Internally there are soldering pads for the programmer connector. There is a DTR, RX, TX, GND connector place, which reminds me of a arduino type serial programming interface.
My pin config estimate:
Ail-L - PD4
Elev - PD5
Rud - PD6
Ail-R - PD7
Ail - PB0
Ele - PB1
Rud - PB2
Aux - PB3
Pitch - ADC6
Yaw - ADC3
Roll - ADC1
Processor runs from 3.3V onboard regulator.
