Parts
| Qty | Part | Value | In layout |
|---|---|---|---|
| 1 | Arduino Nano The USB socket points to the mark in the layout; the module plugs into two female headers. | U1 | |
| 1 | Screw terminal 2-pin, 5.08 mm pitch | X1 | |
| 2 | Female header 15-pin, 2.54 mm pitch |
You also need: soldering iron (about 30 W, fine tip), 0.5 to 1 mm solder with flux, side cutters and a multimeter.
Assembly
- Mill the board: isolate the copper first, then drill, and finally mill out the holes and the outline. The order is shown in the Milling panel.
- Cut through the holding tabs, deburr the edges and rub the copper bright with a scouring pad. After that, do not touch the copper side with your fingers.
- Use a magnifier and a continuity tester to look for leftover copper between neighbouring traces; cut any bridges with a craft knife.
- Insert the parts from the side without copper and solder them on the copper side. Fit low parts first: resistors and diodes, then sockets and transistors, and finally capacitors, terminals and large parts.
- Solder each lead for about two seconds at around 330 °C: tip on pad and lead, feed solder until it flows all round. Then clip the leads just above the joint.
- Solder the two female headers. To keep them straight, leave the Nano plugged in while soldering and tack only the outer pins first.
- Fit the outer rows and the rows for 5 V and GND with male or female headers as needed, and the terminal X1 last.
- Visual check: no solder bridges, no dull, balled-up joints. Remove flux residue with isopropyl alcohol and an old toothbrush.
Test and power up
- Before switching on for the first time, check with the meter that there is no short between plus and minus of the supply. Power up the first time on a bench supply with current limiting if possible.
- Plug in the Nano with the USB socket towards the mark and connect it via USB: the Nano's power LED lights up.
- There are 5 V between the 5V and GND rows. Without USB, X1 powers the Nano with 7 to 12 V via VIN.
- Finally protect the copper side against oxidation with solder lacquer or plastic spray.
