+To add a speaker, you can use the [ReSpeaker 2-Mics Pi Hat](https://www.seeedstudio.com/ReSpeaker-2-Mics-Pi-HAT.html). This is an external board that contains 2 MEMS microphones, as well as a speaker connector and headphone socket.
+

+
+You will need to add either headphones, a speaker with a 3.5mm jack, or a speaker with a JST connection such as the [Mono Enclosed Speaker - 2W 6 Ohm](https://www.seeedstudio.com/Mono-Enclosed-Speaker-2W-6-Ohm-p-2832.html).
+
+To connect the ReSpeaker 2-Mics Pi Hat you will need 40 pin-to-pin (also referred to as male-to-male) jumper cables.
+
+> 💁 If you are comfortable soldering, then you can use the [40 Pin Raspberry Pi Hat Adapter Board For Wio Terminal](https://www.seeedstudio.com/40-Pin-Raspberry-Pi-Hat-Adapter-Board-For-Wio-Terminal-p-4730.html) to connect the ReSpeaker.
+
+### Task - connect the ReSpeaker Pi Hat
+
+1. With the Wio Terminal powered off, connect the ReSpeaker 2-Mics Pi Hat to the Wio Terminal using the jumper leads and the GPIO sockets on the back of the Wio Terminal:
+
+    The pins need to be connected in this way:
+
+    ![A pin diagram](../../../images/wio-respeaker-wiring-0.png)
+
+1. Position the ReSpeaker and Wio Terminal with the GPIO sockets facing up, and on the left-hand side.
+
+1. Start from the socket on the top left of the GPIO socket on the ReSpeaker. Connect a pin-to-pin jumper cable from the top left socket of the ReSpeaker to the top left socket of the Wio Terminal.
+
+1. Repeat this all the way down the GPIO sockets on the left hand side. Make sure the pins are in firmly.

+
+    > 💁 If your jumper cables are connected into ribbons, keep them all together - it makes it easier to ensure you have connected all the cables in order.
+
+1. Repeat the process using the right hand GPIO sockets on the ReSpeaker and Wio Terminal. These cables need to go around the cables that are already in place.

+
+    > 💁 If your jumper cables are connected into ribbons, split them into two ribbons. Pass one each side of the existing cables.
+
+    > 💁 You can use sticky tape to hold the pins into a block to help stop any coming out as you are connecting them all.

+1. You will need to add a speaker.
+
+    * If you are using a speaker with a JST cable, connect it to the JST port on the ReSpeaker.
+
+      ![A speaker connected to the ReSpeaker with a JST cable](../../../images/respeaker-jst-speaker.png)
+
+    * If you are using a speaker with a 3.5mm jack, or headphones, insert them into the 3.5mm jack socket.
