| - | under construction | + | |{{wavebubble:1.jpg|}}|Place the PCB in your vise. For this assembly diagram I will use the lithium ion board, the AAA board is easier.| |
| + | |{{wavebubble:2.jpg|}}|Solder in the DC jack and the FTDI chip. Solderpaste is suggested here.| | ||
| + | |{{wavebubble:3.jpg|}}|Solder in the USB jack. You can now test whether this works by plugging it into a computer.| | ||
| + | |{{wavebubble:4.jpg|}}|Solder in the rest of the components, the low power charging circuitry is not necessary. | | ||
| + | |--|If you are using a battery without protection circuitry, attach it. Solder in the battery. The left pad is + and the right pad is -. | | ||
