Note: Not tested!
This tiny board is again a clone from the original Xeno-GC.
This one not uses the Caps on the Voltage line to reduce size. Don’t know if it cause any problem. As well it doesn’t feature the Status LED’s. Without an ISP header, so programming should happen before installation on the PCB.
Part list:
MCU: ATMEGA8L-8AU
1K: 1KΩ 0201 resistor.
2 layer board of 0.60 x 0.45 inches (15.3 x 11.5 mm).

64 channel I/O board.
This board is designed for custom OpenLCB firmware supporting up to 256 channels of i2c auto detected hardware. Chain 2 boards together for 128 channels of I/O per node. (Board address is handled automatically)
Use in conjunction with PCA96685 pwm drivers for up to 128 turnouts with feedback and frog juice control using 4x 16 servo driver boards on ebay. (Split 40 pin IDC to two 20 pin IDC)
Provides onboard EEPROM for configuration, status and CDI template data. 40 pin headers map to 16x RJ45 plugs providing 4 channels each plus power and ground.
2 layer board of 2.91 x 5.66 inches (73.8 x 143.7 mm).

An AVR programmer/tool based on the ATmega32u4. It includes many breakouts for many different functions, including ISP and UART, as well as selectable target power voltage.
BOM:
R2,R3: 22 ohm 0805
R4,R5,R6,R7,R8: 2.2K ohm 0805
C4: 10uF 0805
C2: 0.1uF 0805
C3: 1uF 0805
D1,D5: Red LED 0805 (Marked “Error” and “!” on the board)
D2: Blue LED 0805 (Marked “Power”)
D3: Yellow LED 0805 (Marked “Prog”)
D4: Green LED 0805 (Marked “Ready”)
U1: ATMEGA32U4-AU (TQFP)
Y1: 16 Mhz Murata resonator
SW4: EVQQ2 switch
J1: USB_A Molex 48037-0001
All other connectors are 2.54 pitch male pin headers. Jumpers J7, J8, J9 and J10 require pin jumpers like: http://a.co/bSmXWlI to bridge at least two pins for operation.
