Assembly

NOTE
This guide from the wiki starts with the minimal configuration for usage with 5V power supply and 5V Addressable LEDs. The additional options are added manually.

1. Solder jumpers¶

• Jumpers have to be soldered first according to chosen configuration:
• IO1-IO3 - Let you choose D2 output, GPIO1 or GPIO3 (Feature added in shield v2.1);
• IO15 (ESP32 only)- Let you choose if your output 15 is shifted or not (soldered left not shifted);
• IO15-1 (ESP32 only) - Must be soldered if output 15 is shifted;
• IO14 (ESP32 only) - Let you choose if your output 14 is shifted or not (soldered right not shifted);
• IO14-1 (ESP32 only) - Must be soldered if output 14 is shifted;
• J-R2 - If soldered bypassing resistor R2;
• J-R1 - Soldered if resistor R1 must be used;

2. Level shifter and passive low profile elements¶

• First solder components with low profile.
• Level shifter (LV1)
• Check correct orientation (notch of the level shifter must be alined with silk screen on board)
• Solder resistors R3
• Diodes D1 and D2 (Check diodes orientation with markings on PCB).

3. Headers¶

• Two headers H1 and H2
• Mosfet Q1 (Q1)
• Capacitor C1 (C1)

4. Fuse holder, Resettable fuse, Relay¶

• Resettable fuse F2
• Solder fuse holder F1
• Last relay K1
• Solder wire jumper on place of power selector.

5. Terminal connector¶

• Terminal connector X1, X2

6. Electrolytic capacitors¶

• And now the capacitors C6 and C2 (pay attention to polarity)

7. Add solder to traces¶

Add good amount of solder to traces shown in red. For more Amps to flow through.

8. Clean your board with 99% isopropyl alcohol¶

And check if you don’t have a solder bridges between soldering pads¶

Fuse and power selector¶

Now put a fuse into the fuse holder. Before you put the jumper on the power selector, do the next step of the wiki first.
