Notes
- Some provided resistor values could differ slightly, as could their band colors; this has no effect on the working of the board.
- Use a pair of tweezers to solder the two SMD parts. Apply a blob of solder on one pad, then seat the SMD part with the tweezers while heating the already applied solder blob. When the part is seating correctly, solder the remaining pad(s).
- When preferred, other LED colors can be used. Make sure to check if the values of the resistor R1 and resistor network RN1 are correct for the LEDs used (see Schematics).
- Put the LED spacer between the legs of the red LED (D1) before soldering.
Important Information
If a finished 8-bit Workbench is available: on a flat table, mount the standoffs and insert the unsoldered pin headers (J1, J3) into the female busses of the Workbench to have them perfectly aligned before soldering them.
Check the LED (D1-D3) polarity. The long leg is the anode (+) and the short leg the cathode (-). The short leg should go through the square pad and the long leg through the round pad.
Before applying power, check J1-J5 for shorts between all side to side pins using a multimeter in continuity mode. Do the same for the voltage regulator (U1) on the backside.
