- Install all components as indicated on the parts placement diagram.
- LCD - Do NOT install the 10 ohm resistor, trim pot, or 2x8 pin header just above the LCD unless you are using a parallel LCD interface instead of the I2C bus interface.
- OLED - When installing the 1.3" OLED display, note that there are many versions available with different pin assignments. There are two rows of solder pads that can be used for various types of displays. The upper row of 4 solder pads are for displays with pin assignments: GND, VCC, SCL, SDA. The second row of pins are for displays with pin assignments: VCC, GND, SCL, SDA. Make sure you pick the proper solder pads to match your display.
- OLED - When wiring the OLED display, you can use a header socket on the top row or hookup wire between the display and the circuit board.
- OLED - Use 4-40 screws in the two top holes to mount the OLED to 1/2" standoffs. The holes on the bottom edge are too close to the glass of the display and some 4-40 screw heads will crack the glass. Use small diameter screw heads or just leave them off. The upper holes will support the display just fine.

Protoboard Rev 1
- This board directly supports only +5v processors and peripherals. Works great with the Ardunio Mega and PIC but not the Raspberry Pi Zero. You can make it work if you add a 3.3v regulator and cut the +5v traces going to the protoboard area.
- Make sure you ONLY install the four 8 pin SIP female headers on the bottom of the board on the inner most solder pads. Do not install dual row female headers because they will short out signals on the motherboard.
